ZL8X - K3 firmware
Locked

There is K3 subrx IF output - if you do the N2QT et al mod. It is just adding a Clifton Labs U-10000 preamp under the subrx enclosure and running a pigtail coax to the currently unsued REF IN hole in the back of the K3. In using SKIMMER on the subrx results in the following nice options when in the normal split mode: 1) Clicking on the last station worked in SKIMMER sends VFO B (xmit VFO) to that frequency. 2) Clicking on the spot sent by SKIMMER to the logging program sends VFO A there. Great for S&P. The mod isn't hard to do and is well worth the effort. 73 de Brian/K3KO ----- No virus found in this message.

How about changing the subject line for this thread.

Brian that mod isn't necessary to work split pileups using Skimmer. Using VFO B on the DX frequency and A on the pileup frequency (and TX) is very simple. The mod is nice if you want to use Sub while running on the Main in contests but that's not the question that was asked. 73, Bill |

Looks like about 85% of the advice I've received is in favor of adding the
KRX3 first, and I agree with that. But I'm surprised nobody has mentioned this benefit as well: The other good reason (IMO) for adding the KRX3 first -- and setting it up as VFO B to listen to the DX station, while listening to the pileup with the main receiver on VFO A -- is because if you do it that way, you can use the new super-fast QSK option, which is AWESOME, except that you can't work a split pileup with it on a single receiver. This makes it kinda useless for DXing. And if you want to send at the same reasonable speed that the DX station is sending (usually 25-35 WPM), the existing QSK modes that do work with split VFOs on a single receiver don't really let you hear the DX station between code elements at those speeds, only between characters or sometimes just between words, depending on a number of variables. So, I really do want to be able to use the new super-fast QSK mode, and that requires the KRX3. That pretty much tips the scales for me. It also means I can easily hook up CW SKIMMER on the main receiver's IF output port and monitor the pileup, with the K3 transmitter following automatically. Sounds like the way to go. Thanks to all, but feel free to continue the thread. I've changed the subject line as somebody else suggested.
