That used to be very true, and across the board with manufacturers -- but not in TX, because most pre-70's era ham transceivers were designed to be AM only in the first place. Even then, the radios that were capable of operating in SBB suffered on the receive sensitivity end of things anyhow...

Dittoes what Capt Kilowatt stated. Byrd meters have been around for eons and are kind of hard to beat for accuracy due to the slug system they use. Coaxial Dynamics' meters are just as accurate, and Telepost makes some good maters too. But it all boils down to reputation. I've sold all my Byrd...

LOL!! OK, let's just go with 60A to be safe. This cannot end well. So I'm out.

Yep, 20A should be adequate then (barely); P/E=I OR 250W / 12V = 20.8A So 30A supply would be perfect.

I thought it was capable of 400W pep. If all it can do is 120W, sure, a 20A should do finel. I'll have to check the specs on that amp again.

You'll need at least an additional 40A power supply. This is usually not a problem in a mobile installation, but you'll need a big power supply if not.

Congratulations! You're going to love all those new bands. It would amaze you just how many hams were CBer's, and how a lot of THOSE are still active on 11M to this day.

Looks like 60 uF @ 350VDC / 60uF @350VDC / 60uF @ 50VDC.. If you cannot find the exact can, order separate "radial" capacitors for each one. If you cannot even find individual caps at those values, go the next closest value in capacitance and voltage rating higher, (NEVER lower). Observe...

Sure, Bob. That should work ---- MAYBE.. But the film is cheaper (though, not by much) and you'll have enough film to do about 8 RCI-29xx displays from each sheet. Also, (the "maybe" part), I'd re-flow most of those solder joints before plugging that puppy in. They're deplorable! Who did they...

The short answer is maybe. And if so, it's risky. And it depends on the damage. Those displays use a Liquid Crystal "sandwich" with a polarized film on the front. Such displays are easily warped by heat in the vehicles they're installed in. The sandwich 'bread' is usually glass. It don't warp...

You're correct in your assumptions. It's an inline bandpass filter to prevent TVI at the source. It's obsolete today, as modern TVs can do the job to begin with. When that was made, that wasn't the case, and even some radios weren't that good at filtering-out harmonics. That is where your box...

I agree, the radiation pattern is 'whack', considering what is required on 11M. Even so, ANY antenna is scalable to ANY other frequency and perform the same as their design frequency. The only limiting factors are the sizes they become at lower freqs. A microwave dish might have 16Dbi gain...

If the thread is still open, it should be fair game. A firearm forum I go to every day (GlockTalk) never closes a thread, and about a year ago, they "upgraded" their software.. You should see the vampires it's built-in algorithm drags up as 'suggested reading" now! But yeah, 2009 is ancient. ;)...

Item found!! I actually found a complete "L chassis"in good condition amongst my junk amps.

Inspect the 811's (or 572 whatever yours is tubed with), and inspect the plates. See pics below.... Outside of the missing glass (removed to improve images), if they are not a solid blackish color, and have those shiny, deformed areas on them as seen in these two pics, the plate is likely...

I DJ'd, and 'roadied' for WLTC from 1987 through 1992. One of our favorite 'bumps' was "WLTC... Screw that. We play the music WE like!!"

Thanks a bunch! You cannot know how grateful I am for that info! I truly have looked high n low for it, and at every chance I had. I'll give that a try later on this evening or tomorrow. I'll need to study Rich's treatise on the topic you linked to also. I've never had to deal with this issue on...

NP, I live in Lehigh Acres. Florida. Where are you? By your user name, I'll guess Alaska? Yeah, I may just have to 'pull the trigger' on that amp. Cosmetically, it looks showroom. And I have a new MP of Chinesium "RF Parts" tubes to slap into it.

I'm rebuilding a neglected, 'monobanded' SB220. I love these old amps and have a nasty habit of adopting and restoring them. But right now, I am looking for a complete input network assembly.. Sometimes this assembly is called the "L-chassis". Band switch conditions aren't important, as I...
