Re: [Elecraft] [K3] clarification on VFO and 2nd Rx

2007-10-16 Thread Bob Cunnings
For years here at my place of employment we've offered UHF diversity receivers where, instead of switching between the two signals, we blend the audio outputs of the receivers in a ratio controlled by the RF level of the received signals in the two receiver sections. Once done using analog circuit

David, I think the real answer to those extensions will have to wait until after the KRX3 ships. I really don't know how RTI and XIT interact with the sub-receiver, nor have I though about how to best utilize it in situations like you have posed. 73, Don W3FPR David Ferrington, M0XDF wrote

Arrrhhh For RIT below, read XIT Thank you Don, I kinda thought that was how it was and in typing the mail, came to realise I need to think in terms as you stated. So then I just wanted clarification. I have on more question then - lets say I have the KRX3 (I will when it ships :-). I'm work

David, It may help if you mentally divorce the physical VFOs from the A and B designations and think of the DISPLAYED frequencies. The main receiver will receive on whatever frequency is displayed on the VFO A readout, the sub-receiver (if installed) will receive on whatever frequency is dis

You might have seen my post asking for clarification too. I'm pretty sure KRX3 will always use VFOb and can not be switched at present. My understanding is that with the sub on, its audio goes to the right channel of the stereo output and VFOa's audio goes to the left channel. That's regardless of

2007-10-16 Thread Barry N1EU
I'm unclear about VFOA/B functionality when using the main and subreceiver in diversity mode (i.e., tuned to same frequency) and the transmitter in split mode. It seems that the subrx needs to be assigned to VFOA in this case but I'm not sure if the K3 provides that flexibility (like the Orion).

I seem to be very confused about the way VFOa and b control transmit and want to get some clarification please. I started (in 2004) with an Yaesu FT-857 and am still using that, the way it works may well have coloured my understanding. If I may, let me describe what I understand based on that: Th
