Rick, the K2 works ok for the wider modes, with the SSB module built in. I have used it e.g. for MT63 2k, and it worked fine.
You do need the modification which temperature-compensates the vfo. MFSK16 is no problem with the K2, I have used it succesfully with gMFSK. I bought the FT897D, which has a very precise VCXO later, because it has 6 and 2 meters and 70 cm, so I take only one rig in the camper (more space left for bottles to cool the operator). I can leave that on for month and it will stay within 10 Hz at any temp. 73, Rein EA/PA0R/P > -----Ursprüngliche Nachricht----- > Von: digitalradio@yahoogroups.com > Gesendet: 13.03.08 00:50:04 > An: digitalradio@yahoogroups.com > Betreff: [digitalradio] Does K2 work OK for wider digital modes? > > With some of the recent comments about filtering and the use of the > Elecraft K2, I was wondering if these rigs are OK for the wider digital > modes that can exceed 2000 Hz. > > Also, do you find that most rigs with no TCXO (such as the K2), will > work OK for the digital modes, including MFSK16 and similar modes that > require very close tolerance on frequency stability? > > This was one of the things that prompted me to buy the ICOM IC-7000 for > my wife, since the TCXO is built in and it has something around 0.5 ppm > frequency stability.
