The old argument or idea you never need an amplifier is just as silly as saying you always do need an amplifier. I would guess the "rule" we never need -140dBm sensitivity is based on a suburban loc

First I have a question. How does a voice keyer send CW?? Or does it have a CW key output? To correct some misinformation about the MFJ432, it has been ground isolated since I was given the job of re

I wouldn't. But all that aside, I just wanted to clarify the redesigned unit has isolated audio grounds, and an isolation transformer. I think I caught all of the problems in the rework, including "

With no RF amp, it is possible to get into the -130dB or better range on sensitivity. But the biggest problems are actually poor filtering, poor gain distribution, and simple design errors. Narrow f

Using a noise blanker is a bad idea, but you know with a simple design change we COULD use our blankers with overload problems....but that is for another day. After some more thought, I revisited th

The pin spacing and size is very close, but a tiny bit different than all the other DIN plugs in the world. I spent about 30 hours looking for a replacement, and the only source I found is Yaesu. Yo

I don't really understand people who feel obligated to insult OO's, or make light of their efforts. This seems to be a trend that has spilled over from the rest of society that anything we do is OK.

it doesn't matter at all, not one tiny bit, if we like to use different receive tones. As long as the transmitter is properly netted to the receiver in EACH station, they will be on the same frequen

I disagree with Tadek on several points, but most important are: 1.) I work much more than 160. I find I need 80dB or more of close-spaced IM3 and blocking on 80 meters and higher. 2.) In a noisy loc
