Well yeah exactly right. I only monitor reflected power mobile but I'm also capable of the KW's range. In an emergency of course! But very high energy harmonic output is going to reveal itself to the base level operator as a antenna they can't "seem to tune" If you're running half a kw mobile...

Another simple way to know your harmonic output is just socially unacceptable is you will see reflected power (swr) that you just can't seem to tune out seeing how your antenna isn't resonant at double the intended frequency

"Good question. Here's the way it was explained to me by one of the moderators: Look at the data sheet for the transistor in the amp, they have a voltage requirement, input power requirement, and an output spec, as well as other bits of info. It states that they are spec'd to run at 12.5v; all...

These are generally pretty capable little 2 bangers. But they all have floating chassis grounds and the chassis is capacitively coupled to electrical ground. This is where many of their problems arise from. At all 4 corners of the PCB replace the disc caps that are for "grounding" with...

Hey Rogerbird do you plan on replacing the finals and repairing it? If not I'd be interested in it as it is. Adam

Well as an OEM who started small I have to say your conjecture about builders generally not caring, to sum rhem up. Would only come from someone who has never designed, built and attached their name or 'Brand' to it. There's far easier ways to make money then successfully selling electronics...

I'm always a day late to show. Congrats Ranch

Hey fellas I wanted to take a moment to let you know Retro is a stand up guy. He stuck with me through problem after problem. All of which were not the fault of either of us. But he put in the time because I had expressed that I really wanted the bloody rig and it was fortunate that I included...

I've found a rig folks. Thanks Retro

Okay well tell me more when you can

Looking for a complete Siltronix SSB-23 for nostalgic reasons. If it doesn't work but is complete that is fine. Not being butchered is my goal. Just got hosed on ebay and it was missing the parts you can't source.. Easily in the 150-200$ range for a complete and pretty one Thanks!

Funny. I got here looking for info on the Siltronix SLM-100 but all I found was a bunch of posers whining about not being able to talk smack on YouTube comments. Fellas. You really have no idea how obvious you are to those of us that "Do" If you were feeding your family with your own brand...

Oh man this is so true. I started with a 5 channel Johnson Measenger and a magmount in the gutter, in 7 grade. By the Dayton fest of 1999 in 9th grade I think, in passed and got my ticket. Well radio spawned my entire unrelated electronics career. I easily stepped away from radio for 10...

Yeah this was case when it first became available, you're right. Dudes running ungrounded antennas would be the ones to see a difference at that if there was any to be had

I've run both the 2000 and the maco v58 and while the macro had slightly better performance for my installation I have to say the average radio guy anymore really isn't a hard-core engineer/scientist so with that said the imax 2000 is a hell of allot easier to install and tune. The 2000 has a...

Is the antenna mast properly grounded? Like lightning strike level grounded. Solid copper ground wire and a 8ft copper ground rod in the ground? The A99 would work well without, though for safety reasons it's foolish to not properly ground it. But I've helped guys solve this very issue with...

I read the entire thread. I'm impressed. You accomplished allot in very little time while knowing little to begin with. Those with 20+ years experience in their specialty are able to chase the last 5% as I call it, easily. And all too easily forget their 95% cost 20 years. In the end you...

Man this is reading like a vintage aircraft restoration. 138xlr huh. Kinda feel like I need to buy one now, seeing all the determination here. Mind you I only design/build tube guitar amps to feed myself and wipe my ass... Recap the bloody rig. There is never a reason to be this obstinate...

This comes up allot. Sd1446s being 70 watt finals at 12.5Vdc. The sheet does say that. But that's also at 70mhz. Or is it 50? Anyhow 27/28 is allot lower then both as far as a transistor is concerned. When you operate a sd1446 at a more realistic 14Vdc and at 27/28mhz they put out allot more...

Wow some of these are phenomenal. Late 90s in high school, the night before Thanksgiving up till 5am jabbering. I worked southern Australia and Hawaii on 27.225 AM with a Ranger 2970 driving an Ameritron AL-811h.. with RCA's in it! And I wasn't on the 3 element beam. I was on the Maco 5/8...
