What if element one is 90 degrees out of phase?

:):D

Now that is something new to me! Circular Polarization!

Thanks guys I appreciate the input, it sure is a heavy antenna! (More than likely this is going be yet another long-term project!)

Pic of the bias circuit after refresh.

I understand your run down, the final is not "volted". This radio has seen a tortured past, many things have been found failed/misadjusted. I'm doing my best to repair it and return it close to "stock", I've been removing mods as I find them. My issue is a steady 13.7 volts on the collectors...

Small update! The orange wire feeding TP7, TP8 from the mode select switch provides 13.78 Volts regardless of mode selected, I believe I have a faulty mode switch, what do you say? [I should review the schematic thoroughly before asking..]

Thanks! I'm glad i'm here as well, I appreciate it!

What do you guys think about this antenna? I don't read much into the "specs" ("audio gain") and some values seem off. Besides the marketing and fake or wrong gain figures, what do you think? http://www.gizmotchy.com/Extremegizmotchy.html It almost looks like an 8 element Gizmotchy, an...

In that regard the program is a success! Yeah that Johnny Cash tune is pretty depressing, I only listen to it when I'm in a really depressed kind of mood. But yeah I don't know if everybody's heard it so I figured I would share. Working on staying positive though, today is a new day! :)

Nothing quite like government-sanctioned heroin to keep the populace sedated. Those clinics are supposed to get people off of drugs, but they basically just replace what they used to use on the streets with methadone. Those clinics and the way they run them are not set up to get people...

The beauty of youth is fleeting, our innocence was gone before we knew what we had. This empire of dirt... Damn I'm depressed, LOL. The internet did it to me... (pass the blame around)

All of society has become accustomed to rapid consumption, we would not know how to survive without TV dinners and plastic silverware.. :/ We produce goods not for quality, but quantity, we design and sell devices that SHOULD fail in a set amount of time, because "they" make more money selling...

You got it! :) Thank you.

VR10 high leg 8.xx volts wiper something like 6 volts. It seems the buffer and the AM regulator have the correct voltages present. C154 is not present, not sure if it should be. (don't see it silk screened on 148/Grant) The 12 volts going to the collectors disappears when I pull TP7 & TP8...

MV1Y and MV13YH? (they test ok) Or D76? Thanks guys! The radio can now be operated in single sideband modes without any excessive current draw. I am measuring 12.4 volts on the collectors of the driver and final at idle on A.M. which seems off if I recall correctly. Just rebuilt the PA and...

Okay with the bias and RF PA circuits removed the radio is consuming 220 mA through the fuse holder while off, and approx. 750 mA while in RX mode, this changes by about 20 mA between modes. (I'll have to look at the Sam's) So if it was drawing over 2 amps in RX before, and only 750 mA now...

Before Cleaning Attempt: After Cleaning Attempt: I'd say it got a little bit warm down in there! More to follow later in the week..

OKay.. as the title says the radio wants to smoke (it won't blow a 4 amp fuse) itself when switched into SSB mode, I measured the voltage at the collectors of driver and final, and when I switch the radio to SSB the voltage shunts to ground and the current draw increase, a lot. This is in RX...

If it doesn't look good on the 'scope, it's not a good mod.
