Have this issue with a Siro Gainmaster after an ice storm, 3 SWR. I also coated the fiberglass with a clear fluoropolymer with a silicone to make the surface slick. The trees are completely covered in ice, the antenna is only iced on what I guess is the leading edge, about a half inch wide...

Have you put one of these together? I was looking at the cheapo RTL-SDR dongles, only one that looks decent is the EL4000 board that is widebanded. Part I don't understand with those dongles is using a driver and RF sampler for HF. The Airspy products look like that is included. Thanks for...

I have been poking around trying to understand how to set something like this up. Would like to have a waterfall display like those fancy ham rigs! Plan is to mount a wideband antenna on top of the tv tower and use the 75 ohm coax that feeds into the house (don't watch TV, my mother in law who...

I bought an old 135 mainly for the mic that came with it (the Turner works great), smelled like it was a two pack a day smoker. The radio has a channel selector on top, I assume to change the crystal sets. Radio powers on, can receive on one channel, no transmit. Wondering if anyone has used...

@Handy Andy @nomadradio The converter was the culprit, works excellent on a 5 pin connector. Now to see what a 5 to 4 pin converter does...

I hear a ton of noise coming from solar powered bus stops, sounds like a heartbeat and is very loud, much worse than noise from the traffic signal lights. Only way to avoid is get out of there. The cheapo LED desk lamp at my house makes horrendous noise, while the 500 watt LED driver for my...

@Dereka5 I saw an Italian distributor when I was looking for the KL amps, I imagine you'll have better shipping rate/import fees. https://shop.es-radiotel.it/en/22-linear-amplifiers On a side note, it is rather ridiculous your country, an ally of the US, imposes harsh tariffs on goods coming...

Bought the pair of KL203s from 88 Radio not too long ago. Took about a week and a half to receive, shipped from DNJ.

That D-104 had never been wired to a connector, nor has it ever been used until very recently. Came from the Astatic factory to my work nearly 30 years ago, they apparently forgot how to do brass plating for their limited edition Diamond Eagle run. I figure the 4 pin soldering job I did is OK...

Thanks @Handy Andy I'm going to try the 5 pin connector first and see what happens, I'll be back to study your reply if the regulator continues to shut down. I'll also investigate the battery negative, a local a couple miles away says he hears a hum and that it goes away when I put my finger on...

D-104 lollipop wired for 4 pin, using a 5 pin converter into the 148. I have been trying to set up the mic listening to a SDR about five miles away. Can do a few test keys to adjust the mic before the radio shuts off, have to unplug the power supply to get it working again. The other radios...

Did you turn the power down with the RF power knob or did you go inside and turn it down? Wondering if a KL203 is going to cause problems with a Lincoln II+. My meter is showing just below a 2 watt carrier and 18 watts PEP with the knob turned lowest. I am assuming RM Italy is stating RMS...

Finally got around to setting up the base (still need to find a good desk, equipment is on chairs and the floor for now). I used an 20'9" EZ UP mast, painted it and a Sirio 5/8 gainmaster with brown acrylic enamel, topcoated using a two component fluoropolymer with a silicone additive to make...

@Handy Andy Thanks for your reply. I have read quite a bit here at this forum from you and others, however I find myself lost very quickly. My understanding of electronics is very limited, I barely remember a section on circuits in a physics class 30 years ago. I am trying to learn by reading...

Hello I picked up a Texas Star Skeleton 150 from a local guy with two Toshiba 2290s. Spec sheet on the 2290 says max input 4 watt PEP. I put the amp on the bench, 13.8 volts, running a Cobra 148 with 12 watt PEP. Meter is showing 250 watt PEP. Am I asking for trouble with this set up? I...

Thanks @fourstringburn I'd like to use the Sirio Gain Master, instructions say it should be 3 meters above the roof line. My plan is to use brackets in the brick and stay off the eave. I may have problems with the guy line set-up, I don't want to put holes in the roof. My idea of running...

I have been struggling with a suitable space for a 5/8 vertical. I had been looking at an old tv tripod on the house, others suggested that may lead to big problems. A friend of mine owns a roofing company, I am planning on redoing the roof in the next couple of years, he came out to give me...

Yah, I'm nervous that the existing tripod wouldn't be able to accommodate a 20+ foot antenna up there, strong wind may rip it off. When I get some $$$ I would put up a proper tripod, the existing TV coax goes straight into the house, I want to use less coax for the radio going into the house...

Greetings all, I have been trying to find more information on this subject, most searches point to this forum. I spent time going through old threads about this, couldn't find much on the topic, apologies if I missed this has been covered in the past. I bought a new house and am planning a...
