You need to study the basic stuff in the ARRL Handbook, just like the rest of us did when we started out. Jim Duffer gave you a very good explanation. You don't need to measure the voltage in free sp

That's a really good question, Jason. I've made very careful (and fairly precise) spectrum measurements of my Omni V (just back from factory alignment) with exactly that set of TenTec filters , plus

There are gain settings that need to be set to match each filter. If they aren't right, you'll find poor level match between the filters. Call the phone number in the morning (west coast time) liste

Mine is shot, and I need to find a replacement. I ordered one from Ten Tec, but they're out of stock and expensive too. What are the sources for this relay? I have an early serial number, and it uses

Thanks to all for the quick and very detailed responses on this problem. My older S/N unit clearly uses the Jennings RJ1A, and I ordered two replacements from http://www.mgs4u.com/ for $35 each plus

I could be wrong, but I think the Jennings came first. That's definitely what's in my early vintage 425, and TenTec told me they needed to update the circuit board to accept the newer relay. I don't

This is caused by the cable to these loudspeakers acting as an antenna, and a pin 1 problem inside either the computer's sound card or an active amplifier in the external loudspeaker. Winding the cab

That might be true, but it also might not. First, passive loudspeakers do NOT detect RF. If the loudspeaker has an internal power amp, that power amp CAN detect the RF. Second, you may have not used

Why not just stick a radio and antenna in your car and listen to real QSO's? It doesn't take much listen on 40, 30, and 20 CW. The Lakeview "Hamstick" antennas are very easy to install, and you can g

DSP can be a double-edged sword. You can do all sorts of wild and wonderful things with it, but you can easily "outrun your headlights" if you aren't careful. The biggest issue is, indeed, latency --

A CW operator who isn't using QSK on nets, in contests, and chasing DX is a LID. When you don't have QSK, you are still transmitting when the station you are calling has already come back to someone

I own six radios that do very acceptable QSK. They are a K2/100, Omni A, Omni V, TS-850, FT100D, and IC-746. To say that Ten Tec radios are the only radios that do acceptable QSK (or even good QSK) i

Biased? If it's a bias, it's a bias based on experience. Since QSK is a MUST for me, I won't buy a rig that doesn't do acceptable QSK. But more to the point. When I started doing ham radio (in 1955),
