Pretty close to QTH.com, but maybe you're thinking of a high-end concierge service, where they come to your house and do the swap with white gloves and maybe some psychological counseling? de aa6e
Right, but is there a do it yourself prescription, short of digging in with the probes and actually trying to *understand* things? (Awful thought!) I could/will ask TT, but I wonder if anyone has don
On Mon, Sep 21, 2009 at 12:16 PM, Dr. Gerald N. Johnson <geraldj@weather.net Thanks, Jerry, all good suggestions. There can't be that many PLL's in the synthesizer chain, so finding the circuit proba
Greg, I agree that the fan is too loud. I have lived with it for a long time, but now you're making me think that action may be required! You could take Tony's approach, but another way to do it woul
Rick - You're right that this shouldn't happen without the permission of the author. On the other hand, we all probably know that the Internet is not a great respecter of copyrights. Alas, hams often
Amazing video. The most interesting part was hearing what 20 meter phone was like in the "good old days". A real mess! Very positive about amateur radio. 73 Martin AA6E
Nice marketing buzz, though. The price is about right for a serious tuner IMO. I'm not giving up my Heath SA-2060A, which cost me a lot less back in the day. 73 Martin AA6E alas, not at Dayton
Doug, Thanks for the report. I can see how Stan could say they don't care about the reflector, but I'd be surprised if that's really true for everyone at TT. They certainly need to monitor things for
Ten-Tec has to sell the products they have. The Orion is right at the top on any list of performance specs. (Giving or taking a couple of dB.) It is a much more conventional package and probably easi
They are emphasizing voice quality -- for good reason. We know that TT is also the "CW company", but that doesn't sell radios so well these days. 73 Martin AA6E
Yes, but... It's still worth trying to establish a local RF "ground" -- ensuring that everything in your shack is bonded together. No antenna system is perfect, and many of us have some RF in our sha
If you're in a Faraday Cage, you are not sensitive to currents flowing on the outside, which is where any unbalanced antenna currents should go - assuming no "pin 1" issues. It doesn't help the anten
I've been around since the AM era, myself, but I don't see how DSB AM doesn't take at least twice the bandwidth of SSB for the same voice input. 73 Martin AA6E
X kHz SSB -> 2*X kHz AM DSB (more actually, since there is some SSB bass cutoff > 0 Hz) Choose your X. I wonder if anyone still does DSB suppressed carrier? That was a lot easier to generate and stil
Not quite right! You have to use the sub-receiver, which is general coverage. The sub-receiver can be controlled by either VFO A or B. But you have to be sure the main receiver is not also on the sam
I agree it would be nice if we had such an upgrade path, but I suspect there are changes beyond the CPU board. The local oscillator scheme has changed somewhat, along with the IF filter selection. Th
