Are they really back?  The last post to their blog was in 2012.

Equipment / Scanner beam
« on: September 26, 2020, 1252 UTC »
These might make good scanner antennas (mount for vertical polarization).  In bulk, they are $12 each and have a Type F connector.

They remind me of the scanner beam that Grove sold many years ago.

General Radio Discussion / SK: Dallas Lankford

I hadn’t known of Dr. Lankford’s passing.

Dallas wrote many great articles on antennas and receiver mods for DXing.  He will be missed.

Who are these guys?  They are associated with WIPE, the new HF station in Alpine, NJ, and seem to be connected with the station in Matavia, IL.

A google search on them pops up a lot of stuff.

Also look at the FCC page for items associated with them.  The latest posting includes the
following as operating frequencies:

9.650 MHz
11.850 MHz
13.720 MHz
15.450 MHz

Equipment / IC-7300 as a SWL receiver
« on: July 28, 2020, 1338 UTC »
Recently I was looking at a used Icom R75 receiver that was for sale at Universal Radio.   I realized that while the price was roughly about half the price of a brand new Icom 7300 transceiver, the 7300 had the water fall display and didn’t need any additional hard to find filters.  I have a 7300 I use for day to day ham activities and I am happy with it.

N9EWO recently posted a review of the 7300 as a SWL receiver here:
https://www.qsl.net/n9ewo/ic7300.html

The IC7300, even with its recent price increase, has to be one of the best values in ham/swl radios available.

General Radio Discussion / FCC action against pirates

Pirate radio operators continue to be a problem – particularly in major metropolitan areas. The week before last, the FCC resolved two long-pending cases against pirate operators through negotiated settlements. In one case, the FCC last year initially proposed a fine of $151,005 for the illegal operation. After examining the operator’s finances, the Bureau agreed to a $4,000 fine now, with a penalty of $75,000 should the operator violate the law again (see this decision against an operator called Radio Concorde). In the second case, the FCC had proposed a $453,015 fine last year, but agreed to take $5,000 now, with penalty of $225,000 if the operator violates the terms of the consent decree (see the decision dealing with operator Radio TeleBoston). Last year, we wrote here about the much larger fines initially proposed for these two operators.

In both cases, the FCC seemingly recognized reality in taking the small upfront payments now rather than trying to collect huge fines that likely were beyond the ability of the operators to pay. The FCC also required the surrender of the operator’s equipment and a commitment to stay away from pirate radio for 20 years or face much larger fines. The big fines initially imposed in these cases were set even before Congress enacted the PIRATE Act early this year. The new law allows for fines on illegal operators of $100,000 per day, up to a maximum total fine of $2,000,000. Even without the full effect of the PIRATE Act, these cases show the deterrent effect of these large fines. They get an illegal operator’s attention, which can lead to the shutdown of these unauthorized stations, as happened in these cases. With the pandemic, we worry about even more illegal uses of the broadcast spectrum – and we will write more about that issue here tomorrow.”

General Radio Discussion / Electronic surveillance of protesters
« on: June 12, 2020, 2055 UTC »
News organizations are waking up to apparent electronic surveillance of protesters, as evidenced by ADSB transmissions.

Even if protesters put their phones in “airplane” mode to thwart surveillance, it still helps things as it impedes protester (agitator) use of phones for coordination of their activities...

General Radio Discussion / Lightsquared returns...
« on: April 14, 2020, 1419 UTC »
About 10 years ago, a company called Lightsquared attempted to obtain approval to offer internet services in L band, using frequencies adjacent to those used for GPS.  There was a huge backlash to this because almost all GPS receivers were not designed to work with strong adjacent signals and would be overloaded.  The combined voices of industry, users, and the DOD managed to kill the proposal.

Lightsquared was renamed Ligado, and is back.  It appears they may get the permission they desired from this administration.
