Dr. Gerald N. Johnson writes... I'm hoping that doing so will address an audio quality issue that I have on my V. When I turn the AF knob past about 8 or 9 o'clock, the audio amplifier clips, as we'v
Paul writes... Let me try and explain this in audio terms to make sure I have it right. I will be experimenting with PSK31 soon. When setting up an audio public address system, there will be at least
I spent the evening with the covers off the Omni V to try and address my audio clipping problem. For those who don't recall, the symptoms were clipping at fairly low listening levels by the time the
Tony Berg writes... Tony, those IF/AF mods were documented by Rick, VE7TK. I own his former Omni V.9. An owner between us had removed those mods, but I restored them last night. Rick had left that do
Tony Berg writes... Closer inspection of the Wiki modification revealed why I missed it. It was added a little over a month ago--after I gathered up information from that source. I should have checke
john.brewer@us.schneider-electric.com writes... All of the Ten Tec amps have the keying loop for QSK, it seems to me. My understanding of this operation is that the exciter won't excite until the amp
I'm having a persistent problem with an AL-811 and now I'm wondering if the way my Omni V is keying it might be part of the problem. Synopsis: When working Ducie Island, I tried to tune on 10 meters
Ed writes... Ed, thanks for the response. That's what I'm thinking, but I've already checked it all. The AL-811 is simple--there is the T/R relay, the input tank switched with the input bandswitch, a
Ed writes... I will do that. I did test it for DC continuity, and I suppose for there to be anything else wrong there would need to be some signs of heat damage, which I don't. If you think I should,
Bob McGraw - K4TAX writes... The band switches all look good and test good, with both DC and RF (at low levels from my MFJ-259) continuity through all bands. The problem behavior is the same no matte
Stuart Rohre writes... If the power supply is reasonably stable under 20 amps of load, what about using a forward-biased rectifier to drop the voltage? For example, I see a Fairchild FFH50US60S diode
Dr. Gerald N. Johnson writes... It depends on how long they do so. At 15 volts, a battery will eventually get warm and the electrolyte will start to gas off and even boil. That's bad. But proper alte
Bob McGraw - K4TAX writes... Note that I started with the (stated) assumption that the supply put out a stable 20 amps of current. For me, "stable" means "clean" as well as "consistent". If it can't
A while back I posted a question about audio distortion in my Heil headphones when connected to my Omni V. I received several responses but haven't had much of a chance to dig into it further. And in

Last night and today I had a chance to finally spend some time chasing VP6DX. I worked them on 40 meters last night, and used the RX-320 to receive them while listening to the pileup on their listeni
