Hi,
have elecraft ever considered an adaper for the k2 to drive an
oszilloscope as bandscope? Could be a helpful aid at least for people
running the VHF-transverters.

Karsten, the answer may be even cheaper. There is on going development
in the ham radio circles with Software Defined Radios, or SDR. Look at
this web site for a $ 28.00 kit you can build:

These little boards give you a 40 or 20 meter receiver, with a moderate
bandwidth (depending on your sound card). I use an external M-Audio
"Transit", which has 96 kHz sampling, and plugs in via the USB.
My thought on this little unit is to get a crystal for 4.915 MHz, and
tap the IF of the K2, and then monitor the bandscope on the computer. I
just haven't gotten time to modify one of the two units I ordered.
I was rather stunned when my wife and I walked in the Holland, MI club
meeting last Tuesday night, and fellow K2'r Dave, WD8PUO had brought his
$ 28 SDR kit to the club for a show and tell.
Is any one else on the list experimenting with this SDR as a bandscope
for the K2?
