How does one leave the HV off the tubes ? Do you mean to go in and disconnect an HV lead or leads ? Or do you mean to turn on the power and not apply any drive for a long time ? It would seem awkward
Stuart, Yes, I've seen those switches. But neither of my two amps are so equipped. But I understand that what is meant is truly disconnecting the HV. That's the point I guess. Gary -- Original Messag
It's sort of the perfect example of "your mileage may vary. I like the narrowest filter. Even moreso, I use an outboard DSP filter that also has bandpass capability and I like to crank that down also
Yes indeed on the fishing around ! I have seen that often. In fact, no doubt I am one of the guilty ! <grin> With both IF and DSP filters cranked way way down, I won't hear stations calling even slig
I think not using ALC is fine, if and only if, you know how to manually set the drive level to a point that is appropriate to your amp, and if you do this all the time. If your amp will accept the fu
in not drive splatter Both make good points. Obviously many hams have no idea these days how to use an amp. Many amps need drive levels different from what the exciter can put out. An amp is not an a
Don't forget WHAM....clear channel 50k watts for many many years....and they ran water cooled tubes....I've been there and seen em :) Capital for draggers. junk but
I would not say that all Ten Tec radios are insensitive on 10 meters. Certainly mine are not. Or, did you mean to say that they are quiet on 10 meters in the absence of signals ? 73 de Gary, AA2IZ al
This seems to be a very clear explanation of how it is done, based on actual analysis of the circuit. Thus it seems reasonable to accept that this is how it works. That being so, I wonder why Ten Tec
I like to see a response like this as I can see that Ten Tec is listening, and it gives me some useful information. Thanks Scott ! 73 de Gary, AA2IZ the
Hi Kevin, No, I'm not confusing it. I know what 180 degrees out of phase means, vs. any other phase angle. And I know what a vector sum means. My only mistake was in using the vernacular instead of s
When I want to decide on wire size where voltage drop matters, I simply look up the resistivity of the wire I am specifically using, calculate the voltage drop for the length I contemplate using and
As John has said below, much depends on one's operating preferences. Computer control is a must-have for me. I operate almost all digital modes these days, plus an occasional burst of SSB, and nothin
Rick also makes a great point - the display. My taste is for a huge, 25 inch computer monitor to be my display. Run of course by my computer, which is controlling the Rig. This was nice back when I h
I once had a meter that drifted in exact step with the signal it was measuring, leading me to believe I had a no drift system. Other than that mistake, I've never seen one either. Maybe we can amend
That's right. A zero beat means that the two tones are identical and so their vector sum is zero. Hence no output. Unless of course one does something odd with the phase of the two signals. Is that b
That's what I said Jerry....or at least tried to say. Normally, in applications I have experience with the signals are out of phase and thus cancel. This, in my personal view, is the most useful conf
Here is one possible answer. There are dozens of others. I wanted considerable run time, including a couple lights and stuff. I do NOT operate it portable. So - I have 3 deep discharge batteries of t
