To my understanding as its been explained before the KDVR records the
audio to the memory before the processing but when you play it it is
then injected into that same place in the chain and is thus sent
through the processing. Therefore you can make changes to the
processing settings and replay

Pete,
If you are using HyperTerminal (or most other terminal emulation programs),
you can turn local echo on or off. When doing the kind of testing you're
doing, I turn it OFF to avoid confusion.

The boards as designed by EA3BLQ did not provide a line out audio signal,
so using one of his boards would not provide the type audio you are seeking.
While Tom's (N0SS) board does provide a fixed audio, it also requires that
you make solder connections to the Control Board of your K2. If

Sure. It's called an End Fed Half Wave dipole. Oh, but to some, that's not an

Well if you double the frequency, then add a quarter wavelength of

I beg to differ. A dipole is an antenna with two elements fed at the same

Why don't you use the TS850 to listen to yourself transmitting on the K3

Sadly, doing this test with a brand new USB-to-serial cable, it works
fine. However, that cable to the K3 yields nothing, and there are some
funky voltages on U1 on the KIO3. I'm afraid I may have blown the

You are reading from the newer KPA100 manual and you have an older
