Shortwave Broadcast / UNID: 15.555MHz USB, 20:25UTC

UNID station talking about preaches who want to start fights. Weak, peaked to S1. Pretty much faded out after 20:32UTC.

Shortwave Broadcast / RNZ, 06:40 - 07:00UTC, 11.725MHz AM.

Interesting to find this coming in at that hour where I am, peaking out at S2, but a nice quite noise floor. The program was about a New Zealand prospective on 50 years of the Woodstock festival, with various audio clips from the fest, and what it was like to see Woodstock: The Movie in NZ in the theatres in 1970.

Well, I really didn't mean to ruffle feathers on the digital format wars, albeit I did go on a tangent on what I did with my Zoom H2. (My bad...) And yeah, I agree... Although convenient, MP3 certainly isn't the best sound thing out there. It is the format requested for program distribution, thus why I used it. Now, as far as what to use to record shortwave broadcasts? Anything goes for personal use, really. WMA I feel is overkill for shortwave, but if that's what you have, and the storage space for it, let it fly. I've used WMA for OFF-AIR FM recording for years, and still have those +15 years later. I also have drawers of cassettes from the 70's, 80's, and 90's, to dub over to a digital format when time allows. (But, don't we all?) Anyway, my point is, what I did was just one example. Thus, if there's better, easier, ways to suggest a digital OFF-AIR recording methods, let it fly.

The RF Workbench / Re: Pirate radio wattage

Anyone remember the 5W - 10W  AM Grenade transmitters? When propagation was great, those did reach out. Most ricebox modern 100W transceivers MAX OUT the AM TX carrier at 25W, so only about 4dB more than a 10W Grenade.

Yeah, I'd go with the Zoom H2 as well. When a starting up LPFM station asked if I could do a metal show for them in 2015, I mostly did it old school, with CD DJ decks, MinDisc decks, prerecorded downloads, etc. The 21st Century thing that I used the computer for was Zara Radio automation software for my jingles and back ground music. Anyway, I fed all that through a mixer and the output of that went to the LINE IN of my Zoom H2, where I used the STUDIO LIMIT function. I used 128kbps MP3, where 1hr = 55MB file length. Then I'd USB transferred to a Linux base computer to do any post edits with Audacity. Then, when I like the final product and timings, uploaded to an FTP free site. (Which I'm having trouble finding today.) 5 years ago FTP sites were numerous, and anyone could hit a link in an e-mail, go to that FTP site, and download the show. When it comes to radio and program producing, I'm still old school in producing it, but the Zoom H2 let me marry the best of the old way of doing it, with a 21st Century tweak. Oh!!!! Here's a shortwave example for ya! When Art Bell did his very 1st Midnight In The Desert program, WBCQ aired it on 7490kHz AM, back in July 2015. What I did was set up a Kenwood TS-2000X to USB mode, (To reduce fading and phasing.), and used the radio's headphone output to the Zoom H2. I used 128kbps MP3 MONO mode, (Even though that's overkill with MAX audio going to 5kHz.). What I've later edited out was the drop outs between Art Bell to Keith Roland, and, or, between Keith's Dark Matter Digital Network and the stream that WBCQ use as the feed. (No satellite then, yet.) The results??? A shortwave recording of that very 1st show with somewhat propagational background sounds, but very natural sounding music and voice qualities. I could have recorded that in 48kbps MP3, the Zoom H2's minimum, but.... Anyway, get the Zoom H2, learn all its perks and jerks, and you will not go wrong, but you will want to do test experiments to set it up to have the audio come out as you want to have it, various bit rates, MONO / STEREO, AGC / LIMIT / COMP / none at all, etc. But, once you do, you'll love it.   

All this month, there's been a parade of dump trucks, cement trucks, and excavators, passing our house here to rebuild a bridge 3 miles from here. They all seem to be QSO'ing on CB channel 30, (27.305MHz AM.). Seeing that they pass by the house, it wasn't hard to find them.

For straight, out of the box, it's hard to beat most Kenwood transceivers. There are even modifications to open many of those up to 5kHz TX bandwidth, or better. Not just the the high-end, but the low end bass as well.

General Radio Discussion / Re: Are there no radio laws in Greece?
« on: October 07, 2019, 1709 UTC »
I actually bought one from Greece.  http://www.pll.gr/       I bought the 0 - 20W carrier AM mono TX, since I was always out bid on LPB and Radio Systems TX's. I use this as a Carrier-Current transmitter. Not a bad build, and uses a DDS for the FREQ agile oscillator. I had to educate them on what Carrier-Current coupling was, since they don't seem to use that method of broadcasting over in Europe.

Me too, 2 years ago. My review of the B-Tech UV-25X4,   https://www.eham.net/reviews/detail/13440   (Mine is The Perks And Jerks one.)    The 222MHz side is really the only thing useful to me, since the RX on VHF-high and UHF just suffers too much from out of band IMD. Not a problem on 222MHz, at least. Needless to say, I took that rig out of my truck, due to the IMD and put that TM-241A 2M rig back in. Go with what works. And, it's still true, ya get what ya pay for.

Did I miss somethin'??? Just what motorcycle flick ya talkin' 'bout? Never mind The Pinto, (The beans are better.), what about the Chevette, (Or as we called 'em Shove-Its.), made by:


Talk about a POS that was dumped on high schoolers and college students in the 80's! That Dodge Omni was maybe a slight step up.

Equipment / A possible 2.4GHz STL use from Retekess? Maybe...
« on: October 01, 2019, 1714 UTC »
Radio Jay was doing a review on another portable DSP radio, with so-so performance, but what caught my attention was the company name of the product he reviewed, Retekess. Well, I've never heard of them. A quick search of their product line show some interesting FM transmitters, (None of which are legal in the USA.), and this 2.4GHz audio TX / RX,   https://www.retekess.com/categories/Audio-Monitor-System
A potential STL??? What I don't like is it's yet another appliance on 2.4GHz that may have a potential to mess with wi-fi. Still, intriguing.

Yeah, I still do. It is a nice band, for sure. If you go to hamfest, and the group of friend that you have happen to have 222 MHz HT's, Y'all can have the band to yourselves without desense, walking over each other, lower noise from computers, near out of band interference, etc. It has very slightly less range than 2M, but better than 440MHz. I ran into 222MHz EME enthusiasts that loved the 222 band for EME work. Nice S/N ratio, and about the only interference was a close-by VHF TV CH13, but that's about it. Unfortunately, they could really only make contacts to North American stations. The 222 band is also more sensitive to Temperature Inversions as well, more so than 144MHz. During the VHF ARRL Sweepsteaks, it's another very necessary band, due to double points per contact. Even use to include 222 capabilities for Field Day.  And the National simplex FREQ of 223.500MHz FM? The few of us that have it can talk there all day long. Now, you'd think that with the up and coming DV (Digital Voice.), modes that 222MHz would be utilized more with that. In the 70's and 80's, 222 was used a lot for repeater linking, with better reliability than 430MHz. So, I'd certainly would like to use it more. Unfortunately, with mainly North America being the primary user of the band, overseas manufacturers pretty much ignore it, compared to the 1.2GHz band. Even 902MHz is starting to get more attention, which is good, but 902MHz, and especially 2.4GHz, is pretty much trashed with Part #15 phones, baby monitors, wi-fi, etc. 1.2GHz is gangbusters in Japan, thus the availability in gear there. I hope that 222MHz can be resurrected. I was hoping that the Icom IC-9700 would include it. My Kenwood TS-2000X receives 222MHz FM / AM modes, but doesn't TX there. For that the Kenwoods, TM-741A, TM-3035A, TM-631A, and TH-F6A, for my 222MHz FM needs. Albeit the TH-F6A does RX in SSB and CW modes there.  So, is there 222 hope? That's up to our use of it, or the lack of it.
