QSK and the 2nd receiver

[GW0ETF]

Hi,

Hope this isn't a dumb question but I've never used a rig with a 2nd
receiver anyway.......

So was wondering if when using the K3 with 2nd rx on a single antenna,
will I be able to listen to the 2nd receiver while transmitting on the
first vfo when full qsk is invoked...? eg while calling cq contest on
one band will I be able to tune another band on the 2nd rx for mults etc..?
I've got a feeling I'm in for some new experiences when it finally
arrives..!

73,
Stewart Rolfe, GW0ETF

No Stewart, that is SO2R.

I use SO2V a lot here with the FT1kMP and that is what you will get with
the K3, but a lot better. With the MP you can only listen on the same
band because of the way the sub rx path is routed, although it is
possible on the higher bands The K3 has an independant sub rx so I
assuming you can listen on different bands.

Obviously when the radio goes into transmit the rx antennas are
disconnected. For SO2R here I have a WX0B Sixpak antenna switch at the
base of the tower, a pair of Topten band decoders and two Dunestar 600
bandpass filters in the shack, together with two separate 90m runs of
H100 coax and two 6 way screened cable runs. That's SO2R. It's ggod fun
Do a Google search on WX0B, Topten and SO2R for more info. I can't
actually do SO2R at present as I sold my K2, so egerly awaiting my K3
which I am sure will be Radio 1 in the system.

BTW, in the recent IARU SSB FD, we were using SR2O, otherwise known as
Big Knob Man and Little Knob Man. We used my GU8D-special (designed for
IOTA contest) SR2O unit for switching the mic, ie first one to hit the
footswitch grabs the tx. Good fun.
