a Fifth reason is only a WISH, at this time: Duplex receive on another band (e.g. receive 435-MHz downlink of a satellite while transmitting 145-MHz on the uplink).
I am wondering if it might be possible to do by extracting the sub-Rx IF to a HF receiver (or P3 or other SDR with IQ to a computer running sw that can perform the demod). I suspect the 15-KHz SDR inside the K3 shares ckts between Tx and Rx preventing full-duplex. But if the sub-Rx 1st conversion could function using the Rx antenna while the main radio is in Tx using Ant1 (or 2), this could be done (I think). Two transverters would be used: one to receive and the other to transmit. 73, Ed - KL7UW ------------------------------ Message: 12 Date: Fri, 4 Mar 2011 10:16:22 -0800 From: Wayne Burdick <[email protected]> Subject: Re: [Elecraft] 2nd RX To: Lee Buller <[email protected]> Cc: Elecraft Reflector <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Actually there's a fourth reason. If you use QRQ CW mode (ultra-fast break-in), you can't normally use split or RIT. But if you have the sub receiver installed, you can transmit on VFO A and receive on VFO B, which will achieve the same goal in many situations. 73, Wayne N6KR On Mar 4, 2011, at 10:10 AM, Wayne Burdick wrote: > Hi Lee, > > There are three reasons you might want the sub-RX: (1) diversity; (2) > listening to both your RX and TX frequencies when operating split; (3) > monitoring one band while you operate on the other. > > The K3's sub RX has identical performance to the main RX, so it excels > at all of these applications. > > 73, > Wayne > N6KR 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?
