General Radio Discussion / Find Your Modulation Sweet Spot?
« on: October 19, 2019, 1737 UTC »
This is always good AM info,  https://www.radioworld.com/tech-and-gear/find-your-modulation-sweet-spot

Boomer FWD that to me.

Equipment / Re: USB Pirate Station, audio bandwidth
« on: October 09, 2019, 1906 UTC »
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:

Cheap

Valve
Rattles
Oil

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.

Amateur Radio / Re: 220 Mhz
« on: September 30, 2019, 1837 UTC »
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.

That TPR1630 must be nearer to y'all, since y'all seemed to be the only ones hearing that. Boomer, near P-burgh, has tried jumping from on-line SDR to SDR to catch this. no can do, (As Hall & Oats would sing.) That KCJJ1630,  https://www.1630kcjj.com/   just walks in here too strong in WV. Interesting format that they have though, maybe the latest from Mary J Bly, then AC / DC - Shook Me All Night Long.

Propagation / HF sucks??? Try VHF / UHF this heat wave!
« on: September 27, 2019, 1725 UTC »
Today, starts a big Fall heatwave in the USA Northeast, and already I've noticed some nice VHF / UHF enhancement from Temperature Inversions late at night and early morning. Last night, about 2AM, the Athens, OH NOAA WX station on 162.550MHz was 1/2 scale on an HT I checked it on. (Normally, barely there at around 100 miles from me.) This morning, S9! That, and local FM Translators were getting covered over by out of area FM stations. So, when it reaches +90 degrees in the day, and night dips down to the lower 60's, that temperature swing could mean some nice propagation on the FM, TV, MURS, GMRS, Marine, EMS, Weather, Amateur Radio,  whatever's on the VHF / UHF bands. (Even 6M could be game.)  Don't forget to check for those propagational beacons on 2M, 222MHz, and 432MHz, in CW mode. So, while the lower HF bands are still too noisy, and the upper HF bands still suck, those VHF / UHF bands should be game! Will we see the conditions of late September 2004? That would be nice.

Huh??? To me, it looks like an inspiration from a toilet paper roll. i duh-know, but when I think of origami, I think of papered animals.

Equipment / Re: TECSUN PL-660 FM & SW Issue
« on: September 22, 2019, 0244 UTC »
Believe it, or leave it, I've actually solved problems by resolding with actual 60/40 solder on new gear. The reason??? That damned LoHS, (Lead Free.), solder just sucks! So, ya might try looking for what looks like a cold solder joint. (That maybe many, as well as those leftover solder hairs that are conductive.) Another thing to look for? Under voltage electrolytic capacitors. Last month, I bought a Uniden Bearcat 980SSB CB rig on sale. But, I did take care of one big issue that Uniden still has, under voltage electrolytic CAP's. Sure enough, I've found, and swapped out, three of them. At least, these could be places to start at.

Passing thought there, and it didn't hurt. Much...
