Craig, What you suggest is perfectly possible, but it has nothing whatsoever to do with diversity reception. It is simply dual receive. You can use dual receive either on two separate frequencies, as you suggest (listening to the DX on one receiver and the pileup on the other), or on the same

Craig, What you need is *not* diversity mode. Diversity mode will not allow you to fine tune one receiver differently from the other one. What you need is plain vanilla dual receive. You can either do it in SPLIT mode the way you describe, or reversed (with the transmitter on VFO A, the main

Chuck, When the radio is in CW mode, it is keyed via on-off key closures at its CW key input. It does not accept audio input when it is in CW mode. As far as I am aware, this remark applies to all amateur transceivers, certainly not just the K3. However, unlike most other CW software, fldigi

If the P3 gets its signal from the IF out connector on the KXV3 (or KXV3A), then it will not work with the subRX; the IF out connection from the KXV3 is from the main receiver only. I seem to recall reading posts from someone who had done some surgery on his KRX3 in order to create a similar

LS, With respect to power in PSK, I'd be just as concerned about signal quality (IMD, splatter) as about the power handling capability of the finals. PSK is extremely sensitive to IMD. Instantaneous peak power in PSK can be twice the average power. Even if the amplifier is within its thermal

Brett, Regarding the timing problems you had with CW from a serial port: In this situation the timing is not done by the UART, it is done directly by the CPU toggling the control line (usually DTR) on and off, and is therefore subject to non-RTOS timing problems. If you are using a UART to do

Re: [Elecraft] RTTY via FSK-D

2010-03-04 Thread Richard Ferch
The Invert logic option in MMTTY only applies to PTT. The UART's FSK output cannot be inverted. If you are using EXTFSK, there is an option to invert the FSK logic in EXTFSK. This is immaterial with a K3, though; all you have to do is adjust CONFIG:FSK POL (set it = 1 for normal polarity).

Dick, I believe that both the cause and the solution to your problems lies in MMTTY, not in the K3. Did you have NET on in MMTTY? I suspect that if you turn NET on, that will solve your problem. NET forces MMTTY to use the same frequency on transmit as on receive. If you don't have NET on,

You do *not* have to push the ATU button every time you change bands. See the firmware release notes for MCU 3.03. The ATU remembers the last setting used on each band/antenna input; in fact, it remembers the setting for every 20 kHz segment (every 10 kHz segment on 160m, every 50 kHz segment
