Hi Ron and others, As I very much like to do EME and MS on 144 MHz my RF-power there is higher than average to say the least hi! So as to reduce chances for LFD etc, I decided that I should use FSK CW. It had to be FSK without phasejumps, so SSB-FSK was found to be not suitable.
At the time I decided this, there was no commercial product on the market (and today there still is not) so I had to build something myself. That way my current 2m transceiver was conceived and it is still in use. It now uses a DDS and by manipulating the DDS databus, It makes realtime FSK, virtually without phase-jumps. The neighbours only hear a slight click when I switch the TX on/off. Also since the introduction of WSJT, a convector (developed by PA3BIY) was taken in use, that converts the tones of WSJT to data for the DDS. I have a K2 in use as a secondary transceiver on 144 with the DEM 144-28 ECK built in. I also use this rig as IF for microwave, very recommended I must say! So if the K2 could ever make real FSK, I would be very pleased! But it would probably take a significant hardware modification and software development for just a small group of people, so I guess that the developers at Elecraft will probably think they have something better to do hi! Or?!... 73, Dick PA2DW K2/DEM 144-28ECK KX1 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
