I think the US is getting some MW bands below 160 meters that would be interesting, but unless one has a few acres in the country, I don't see it happening.

I assume you mean the new allocations (in the US) of the 630 and 2200 meter bands?  There are power and antenna restrictions on those bands, and the EIRP on 630 meters will be either 5 or 1 Watt (depending on your location) and 1 Watt on 2200 meters.  This means few will be attempting to build big, full size, efficient antennas, and most will use some kind of physically small loaded antenna for transmit and very likely some kind of loop for receive.  In other words, a regular city lot size piece of land may be perfectly adequate…although I would not like to try those bands in a city style QRM environment.

Do you have a reference to the part I put in bold?
It was in the late 80s or 90s, qst, popcom, or 73 or similar.

I kinda remember it was the son who found the German radio comms and pointed it out to his dad and they apparently understood at least some German and broke in on the ongoing comms, whether this was allowed by the fedz or not at the time. They reported this to US officials and the officials moved quickly to begin monitoring for themselves in a nearby location. The east coast is where it all started but there were other places in the US that reported similar events.

Yes, I have read similar magazine articles going back to the 50’s.  The receive side of the story is pretty well documented, however when it comes to the “transmit back” part of the story it is always fuzzy or word of mouth and as far as I know there is no documentation to support it actually happened.

It makes for a good story, but it is questionable, at best.

The German and Italian aliens and their families in the US had to disable their sets that could rx shortwave, there was a regulation for this and the US gov paid radio repairmen to do this and keep records of the work. The Japanese in the internment camps were likewise allowed ambc radios but not sw sets, the FCC even monitored the camps for transmitters, wich were verboten.

Yes, resident aliens were not allowed SW receivers, that was part of orders 2525, 2526, and 2527.  But this did not apply to US citizens of enemy nation descent.

The man who got me into radio in the 1960’s was an Italian born great uncle, he came over on the same ship as my great grandmothers family in 1908 (that part of our family was Ukrainian) and eventually married my great grandmothers sister.  He became a US citizen (I think by virtue of military service) however his father never did.  He got his ham license in 1935.  He often told me stories of radio operations before, during, and after WW II (he did not serve in WW II, he was too old by then, his service was in WW I and after).  One of the things he told me about was the fact that his father (a radio listener, but not a ham) could NOT have an SW receiver during the war, but he himself, as a US citizen, could.  Within the Italian community where they lived the same thing happened, some folks (not US citizens) were prohibited, while their brothers, sisters, sons, daughters, etc, that were US citizens were not as long as they had separate residences.

There were so many German and Italian descendants in the US as you stated, with many of them being drafted to fight their relatives, it was decided that it would take too many camps to hold them all.

I think there is quite a bit more to this than just it would have taken too many camps.

Less than 2,000 Italians or Italian-Americans ended up in WRA camps during the war, less than 12,000 Germans or German-Americans.  In both cases the vast majority of the internees were foreign nationals, not US citizens by naturalization or by birth.  Under 14,000 total interned, but between the two nationalities there were over 7 million immigrants or first generation US born Americans in the US.

Over 110,000 Japanese or Japanese-Americans were in the camps, with over 60% of them being US citizens, either naturalized or by birth in the US.  And there were only about 127,000 total Japanese or US born Japanese-Americans in the continental US at the time.  Why were so many of them US citizens?  Because essentially no Japanese were allowed to immigrate to the US from 1924 on (Immigration Act of 1924) and few were allowed to enter the country after 1908.  So on the eve of WW II every person of Japanese lineage in the US under the age of 17, and most under the age of 33, were US born US citizens.

All of the interned Italians or Germans would have fit in a single camp used to hold Japanese (the Tule Lake camp held over 18,000 Japanese), and there were 10 camps of Japanese.

The fact is the US public would not have put up with mass internment of Italian and German Americans, it would have been extremely unpopular.  Everyone knew someone of those backgrounds.  These were your neighbors, your friends, popular actors, sports figures, etc.  Not so the Japanese, they were few in number and almost all located in a few areas along the west coast.  Relatively few Americans interacted with people of Japanese descent on a regular basis.

back on topic; I want legal digital dx modes for my cb radio!

With only 40 channelized frequency selections that might be fun, but not a great idea unless specific channels were set aside by regulation for those kinds of modes.

I read in a HAM mag about US HAMs hearing panzer crews in North Africa on their often home-made gear and alerting the US gov to the fact, and how the US rushed to build listening posts (FCC RID) in various US locations where these comms could be received. The US HAMs talked with some of the crews, and each side was amazed to be able to communicate so far, but as each side were experienced radio ops they understood how it was possible. When the North African Wehrmacht radio traffic was first noted in the US, the US was still neutral and HAM radio was in full swing.

Do you have a reference to the part I put in bold?

The North Africa campaign started in mid June, 1940, however German tanks, and their universal use of radio equipment (and the source of most of the receptions I have read about), were not active there until after the Italians requested help, in late 1940.  Most of the Italian M 11/39 and M 13/40 tanks did not carry transceiver gear, the ones that did (often only the command tanks) used the Magneti Marelli RF1CA and later 2CA.  The 1CA did cover the right frequency range.

By late 1940, or even mid June of 1940 (at the start of hostilities in Africa), despite the US being officially neutral, the restrictions on hams were in place to NOT communicate with anyone outside the US.  Anyone admitting to talking with these tank crews would be in violation.  I have heard claims that this happened, but always it has been a case of "this guy told me that some of them did it" with no documented or contemporary sourced references.

Most of the accounts of hearing Africa Corps communications in the US that I have read were stated as being in 1942 and on the US east coast.  By that time the "no ham transmission" restrictions were in place.

And yes, the Germans did allow some ham radio operations during WW II inside Germany.  Operation inside occupied countries was not allowed.  Inside Germany all ham operations were ordered halted, and licenses rescinded, with the invasion of Poland in September of 1939.

In early 1940, possibly as part of a "sustainment of normalcy" effort, Germany started relicensing a limited number of stations.  By mid year 1940 about a dozen ham stations were licensed in Germany.  It appears that at no time during the war did the number of legal ham stations in Germany exceed 200, and for the majority of the conflict the number was under 100.  I suspect the people allowed operation were deemed dependable to the administration, however little can be found on the selection process.  Also it is possible that everyone, hams and "legal" SWLs, may have been required to keep 2 logs, and send one of them to authorities periodically for analysis.  I have seen indications of this requirement, but no one has been able to show me what German regulation stated it.

It is worth noting that the Brits allowed some hams to be active during the later stages of the conflict, and there are reported (but not well documented) cases of British hams in QSO with German hams.

Oddly enough, the US and allies only restricted citizens descended of enemy nationals from using short wave receivers, not the population at large and many US citizens actively sought out enemy broadcasts to gather info on captured US service members who were often mentioned in such broadcasts for propaganda purposes. Then the listener would write a letter to the family of that service member and relate the enemy broadcast details.

I do not think the US restricted citizens descended of enemy nationals from using short wave receivers.  The US restricted foreign nationals (not citizens of the US) in country from such use (via Presidential Proclamation 2525, ss Regulations, 5(f), 2526, and 2527), but not US cits descended of those nations.  2525 addressed Japanese, 2526 addressed Germans, and 2527 addressed Italians.  Lets keep in mind how many millions of first generations Americans in 1940 were descended of German and Italian stock or even naturalized US citizens from those countries.

Because of the bias of the time, both caused by the attack on Pearl Harbor and existing racial issues, these regulations were also applied to some US citizens of Japanese descent, however this was a overstepping of authority (the proclamations were specific to aliens, not US cits).

This is not to be confused with Executive Orders 9066 and 9102, these orders did not restrict radio use, but did allow for the internment of US citizens of Japanese, German, or Italian descent.  Only a very small fraction of German and Italian descended US citizens were impacted by these events, while a large percentage of US citizens of Japanese descent were affected.

As I recall, one rationale for the anti-skip rule was that the phone companies did not want CB radio competing with their profitable long-distance calling services. Of course, that makes no sense nowadays.

CB was not originally conceived as a "hobby" radio service.  It was more or less intended as a less formal or less regulated  alternative to business band radio.  In fact the original rules restricted most channels to communications only with units operating under the same license, with only 7 of the 23 channels available for communications with other licensees.

I think there have been at least three different maximum range regulations for CB over the years.


Propagation, and how history played into the understanding of it :

Frequencies above 20 MHz were in use before WW II, but not very much.  Hams had 10 meters (and 5, 2.5, and 1.25 meters), however there were relatively few hams using that band, this was more the realm of experimentation rather than communications.  The use of these freqs was just starting to take off when the War started to put the brakes on civilian use of them.  The war caused rapid expansion in these freqs, but generally for specific and intentionally short ranged operations.  In 1940 ham use of HF freqs, including 10 meters, was tightly curtailed, no contacts outside the US allowed, and in Dec 1941 all ham operations became illegal (except W1AW transmissions).

Lets keep in mind what a surprise it was that people in the US heard the German tank crews of WW II talking with each other at great distances.  The Fu 5 (the primary tank-to-tank radio used by German forces) worked 22.0 to 33.3 MHz.  These communications were often reported as heard in the US during North African operations, and less often during European operations...with less than complete understanding of why that was.

It is interesting that the German comms were heard more often than the American comms, since the Americans used a similar freq range (the American SCR-508 covered 20.0 to 27.9 MHz), and the US stuff ran more than twice the power of the German radios.  It might be because the Germans used AM and CW, while the US stuff was only FM.  But timing was important also.

The African campaign tank battles occurred between mid 1940 and mid 1943, by June of 1943 it was all over.  US tank operations really peaked after D-Day, or after mid 1944 and until mid 1945.  Solar cycle 17 ended in 1944.  This means that the African campaign happened while Cycle 17 was active, but coming off its peak, and the European campaign started and ended while Cycle 18 was just starting.

When the war ended in late 1945 hams were allowed operations again.  Hams lost 5 and 2.5 meters, but gained 6 and 2 meters.

Solar Cycle 18 (edit, I typo-ed this as 17 in my original post) peaked in 1947.  11 meters was added to the Ham allocation in 1948, but remained under used for many years.  11 meters was taken from hams and given to CB in late 1958, just as Cycle 19 peaked.

What all that comes down to is that 2 Solar Cycle peaks, 17 and 18, happened between the time people started using the area around 10 meters and before 11 meters went to CB.  Hams did have 10 meters during Cycle 16, but only for part of the Cycle, and 16 was a very poor Cycle.  And for one of those Cycles by wartime restriction there was almost no operations other than intentionally short ranged military comms.

When 11 meters went to CB for most of the observed operations history that band was most adequate for short range communications with occasional, and uncommon, long range openings.  11 meters made sense for a short / limited range service and the specified range limit was there to keep the use as originally intended.  The same with the antenna limitations.

Thanks Teotwaki, topped it off with another surprise at 1742z yesterday morning with "L" St Petersburg on 8.495.2MHz CW quite strong 529 report. Strange propagation the last three mornings.

8495.2 kHz should have been F, not L.

Also keep in mind that mag loops work well low to the ground.  So even in an HOA situation if you have a fenced back yard a one meter mag loop can often go outside and do quite well.  I know one individual who disguised a loop as art in his back patio area, so it, and its rotor, ended up in plain sight to everyone, but since it did not look like an antenna there was no issue.

Utility / Re: 8MHz CW, mystery signals...
« on: April 30, 2017, 1253 UTC »
Here is my guess for 8.348 Mhz...The first installation for the Australian Coastal Ocean Radar Network is in the southern section of the Great Barrier Reef (GBR) on the north-east coast. The GBR radar is a phased-array WERA system operating at 8.348 MHz and a 33 KHz bandwidth. It transmits 28 W of power in a CW chirp on a broad-beam antenna and receives on 12 short whip antennas at half-wavelength spacing along the bank at the back of the beach in a sweeping arc of a circle with a large radius of curvature. This configuration produces surface current measurements on a 4.5 km grid scale over ranges of up to 150 km. The two radar stations operate alternately for 5 minutes, giving a map of surface currents every 10 minutes.

WERA, like CODAR, is a coastal surveillance radar as you point out, however, it does not send CW.  The "V ORTN" and then high speed numbers and letters (ass described by Looking-Glass on that frequency) would not be part of a WERA transmission.

and for 8.345 MHZ callsign is similar ....http://qrg.globaltuners.com/?q=Russian+Navy%2C+Baltic+Fleet

Yes, 8345 kHz is a long time Russian naval freq.  I have it in my logs going back more than 10 years on that freq, with similar format callsigns.  RMP is the most common callsign I have on that freq, but I have seen RMR also.

I am moving this thread to the "Utility" forum.  These CW transmissions may be from unidentified sources (particularly the 8348 kHz "ORTN" signal, the others are known sources) however this "HF Mystery Signals" forum is more aimed at unidentified transmission modes, not unidentified sources.

And in some of the AM threads, there seems to be confusion as to where to operate AM on the 2M band. My $0.02 worth here? 144.250MHz - 144.270MHz. Below that is SSB'ers, while above that is propagational beacons. Enjoy and Happy AM mode DX'ing!

The "traditional" AM calling freq is 144.4 MHz, although some areas used 144.45 and 144.425.  However APRS moved in right next to 144.4 and can mess with that freq, and there is the whole OSCAR subband thing.  Locally we still use 144.4 occasionally, however you might find us on 2 meter AM from 144.25 up to 144.45, and even 144.5 or 146.500.  Convention is nice, but remember AM is legal anyplace FM is, and if you apply the same rules as FM simplex, make sure you are not stomping on anyone / thing, there is no reason you can't use AM anywhere you want.

And yeah, we work 2 AM often.  We have a "vintage" night at least once a month, old gear for the most part and odd bands / modes, but anyone is invited to join in, even on a rice burner if it supports the mode.

Second, you need the hot sauce, Frank's Red Hot is the traditional sauce to use. There are others on the market, years ago I used the Crystal brand when I couldn't get Frank's. Make sure you are getting just a cayenne pepper based hot sauce. You do not want to buy a ready made wing sauce. Really, you don't. Don't even think about it.

Franks was the first wings sauce used, and still, in my opinion, the best.  For a while you could not find "Frank's", but it was still around.  In the late 1970's Franks was purchased by Durkee's and the sauce name changed to Durkee's.  It was the same sauce, just renamed.  Eventually they changed back to the Frank's name, although Durkee's still owned it.

Frank's Redhot sauce, I really do put that **** on everything...
