[Elecraft] K3, full duplex satellite operation, XV-144/432 packaging
Hi all, I'm been mulling this over (mostly while riding my bicycle). It looks to me as if the IF freguency for the XV144 or the XV432 can be changed pretty easily. If this is done, then full-duplex using the K3 would become a bit easier. If the firmware for the K3 would allow transverter operation on 28 through 32MHz and some other reasonable IF (22-24 MHz?(I have no idea what would really be right)), then we could use the K3 for full-duplex satellite operation. And if a repackaging job could be done to combine these two units in a single package, then a lot of external cabling might be disposed of, and it might be made to match the K3. 73, doug ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The firmware is the only mandatory thing from Elecraft, I think. I suspect that a tranverter can be modified by the users (preferably with test equipment to verify good performance). And the matching case is gravy, and probably could also be done by the users. 73, doug From: James C.

RE: [Elecraft] K3, full duplex satellite operation, XV-144/432 packaging
How about a K4 using modules for each VHF/UHF band, each plug in with their own antenna socket. If they plugged into a mainframe based on the dual receive of the K3, you could have a self contained satellite/contest rig. Up to 100 Watts would be useful on at least 2m, perhaps conceding less power on the higher bands. I already have an Icom IC-910HX, that is quite an old design and not a very exciting receive specification... Something to base the K4 on though! 73 Dave, G4AON K1, K2 and K3 on order ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Maybe even 1.2 Ghz for the satillites that have Microwave on them. -- W2CVZ, Michael K1#2343 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
