I need the LC values for the elusive model 6 VFO. The factory documents do not have this info. L2 turns and C13, C14 and C15 (or whatever cap combination that was used). Thanks, SL

Gain is not the answer. NF is....

The 1st RF amp, should have the lowest noise figure in the chain. Everything after the 1st, amplifies the noise of that stage. Try to get your hands on 2SC1730 or MPSH10.

The major difference between germanium and schottky, is the forward voltage drop. The schottky tends to be slightly lower, than the germanium. When increasing the voltages to the AGC circuit, that is when things get nasty. Overshoot, overload and has absolutely nothing to contribute, in reducing...

It's snake oil. None of those parts will do any good, some may make things worse. When I see a shottky mod, I reverse it back to germanium. I have used MPSH10's in the RX amp stages and RX pre-amps in linyeeers with success.

Every RF circuit has it's limits. The radio is not designed for 21 MHz operation. 21 MHz is beyond the design limits. Be happy with what you have, it is nice when the upper bands are closed and 15m is open. I measure 49 Watts PEP on mine at 21 MHz.

Amtech USA, not China fake. Because it is the best!

I have one here like new. It is nothing spectacular, but typical NDI SSB chassis. Similar to several other name brand radios, EF Johnson, SBE Tram, etc

VCO's are also a problem in these radios.

MIght be a bad crystal filter

Had Cybernet not made it difficult to work on that radio, I wouldn't be bitching about it. I have a high regard for the radios they made. Not everyone agrees with me, but it's my opinion. The mobile version is the 3-5825B.

The most common fault with that radio, is cold solder joints. The sandwiched boards, make it a major PITA to work on. I have a mobile version here, that I own with this issue a very long time. I am obviously, not looking forward to the repair.

Transistors are pricey. Dow 340, is cheap by comparison.

True 5/8 with ring match, Also a high power version, a Starduster wannabe, and mobiles. Big coil base loaded, but built to last with high power handling capability. Available in UHF, NMO and straight mag. UHF 5" mag mount and NMO 5" mag. Also trunk lip NMO and UHF. All high build quality and...

I can't make an offer without seeing it, in at least some photos. I have been looking for one, that isn't thrashed. Thanks

SSB-50 was my first SSB CB radio, in 1975. I had a VFO 90 and Turner +3, SAMS CB-50. Sold it all in the early 80's I wish I still had it.

Not all Hy-Gain V's are the same.

Word to the wise...Dow 340 , there is no substitute.
