As far as 70cm is concerned you'd have the same issue discussed in an earlier thread about repeaters. The K3 can only tune 2MHz in an IF so you can only cover 432 to 434 MHz. If you were only interested in satellites you could presumably change the crystal in the transverter. You would also need full duplex operation. I don't know if the second receiver allows this. Perhaps someone who has one can confirm or deny this. - Julian, G4ILO.

Re: [Elecraft] K3 and satellite comms
Tom, Satellite comms usually require full duplex operation, and the K3 does not do that, nor can the transmit frequency be changed while transmitting at this time. The year the K3 was first shown at Dayton, I overheard Wayne addressing duplex operation, and he stated that it would *might* be possible when using the transverter outputs, but definitely not from the high power output. The might be possible was qualified by Wayne stating that it would require a lot of testing for interactions. 73, Don W3FPR tom kenville wrote: I am wondering if the K3 might be suitable for satellite comms.

Re: [Elecraft] K3 and satellite comms
Satellite comms usually require full duplex operation, Full duplex is certainly preferred, though by no means required. and the K3 does not do that, Correct, although it *may* become possible through the transverter port in combination with the KRX3 second receiver. nor can the transmit frequency be changed while transmitting at this time. Actually, the K3 transmitter *can* be tuned while transmitting. This was a design requirement from very early in the product design. 73, Lyle KK7P __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
