More than that - you can't QSY whilst transmitting. Pretty sure that most of the digital control side of the K2 goes into sleep mode whilst transmitting, to make sure you don't transmit any digital noise. -- "Nosey" Nick Waterman, Senior Sysadmin. #include [EMAIL PROTECTED] Joining nudist colony!

The K2 cannot do this. More than that - you can't QSY whilst transmitting. After years of using a satellite rig that didn't track, one that did was a massive improvement. But one that will not move at all really makes manually keeping up with doppler a challenge, tracking or no tracking. 73, VR2BrettGraham ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] 432 transverter with 2m transverter and satellites
Then for satellites you are sadly stuffed. But I guess this is a firmware issue which could be 'resolved'. I understand why this may be so, anyway I suggest you band on the door of Eric ever so politely :-) Simon Brown, HB9DRV --- www.hb9drv.ch, www.laax.ch - Original Message - From: "Brian Mury" <[EMAIL PROTECTED]> On Tue, 2005-10-18 at 13:45 +0100, Simon Brown wrote: Regarding software: solutions exist, the big thing to check with the K2 is whether you can change the frequency using the FA; and FB; commands while transmitting - this is essential.

Re: [Elecraft] 432 transverter with 2m transverter and satellites
There are quite a few considerations when working with satellites, here's my opinion which is a bit terse as my back hurts and I want to get on with some new code. Ideally you will have two K2's or a K2 and a good second receiver. Myself I have the IC-7800 and IC-703 and will never own the K2 as I have too many toys as it is (I will buy the KX1 as soon as I get home on Friday). I have been waiting for transverters from Elecraft as I want Elecraft's design quailty - the best thought-out hardware there is. The downside to having one K2 is that you can't accurately align your transmit signal to be on the same frequency as the receive, hence the need for second receiver (or transceiver). You may be perfect but the satellite may not :-) Regarding software: solutions exist, the big thing to check with the K2 is whether you can change the frequency using the FA; and FB; commands while transmitting - this is essential. Not all radios allow changing frequency via computer control while you are transmitting. If you can change transmit frequency while transmitting then you are in business with the provisos above. For the future I am waiting for P3E (a high earth orbit satellite) to be launched in spring of 2006, then I will sort out a 23cms and 13cms solution, at the moment I have ideas for this (sadly not Elecraft-based). Then there's the 47 GHz solution to be sorted out (and financed). What I have to do is sort out how I will do the transverter switching betweem IC-7800/IC-703 and the two transverters with cables and things and stuff but to be honest this really just requires a free evening with a few beers. Simon Brown, HB9DRV --- www.hb9drv.ch, www.laax.ch - Original Message - From: "Rick Tilton" <[EMAIL PROTECTED]> I guess this question is too early but will there be any type of software or hardware interface to put between two K2's or between a 432 and 2m transverter with ONE K2 so that you maybe able to perform inverting and non inverting on the satellites to allow proper tracking of two frequencies? Also will there be software to allow Nova to interface to allow tracking for Doppler. Can this be done with one or two K2's? I guess a little early but something to thing about. I've always dreamed of the possibility of this possibility! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
