Could some kind soul please post the frequencies for
digital operation.  The only one I know is for PSK31
on 28.120 MHz.  I would like to run a bit of MFSK and
Hellschreiber.  I would appreciate any help.  You can't
work 'em if you can't hear 'em!!  73 de Carl  K0BZV

Well,if you are using the IZ8BLY Stream program for MFSK, the suggested frequencies appear on the screen when you start the program. Suggested Hell frequencies are in the FAQ file for IZ8BLY Hellschreiber program. Suggested PSK31 frequencies are listed at the PSK31 web site http://www.kender.es/~edu/psk31.html.

Based on these (except for 40m - changed for Region 2), here are some suggestions (they are not cast in stone, try tuning around):

Band    PSK31   MFSK    HELL
160     1838    1838
80      3580    3580
40      7080    7080    7080
30      10142   10147   10137
20      14070   14080   14063
17      18100   18105
15      21070   21080   21063
12      24920   24929
10      28120   28080   28120

Oops - I copied those frequencies a bit too uncritically. 1.838 MHz is in the 160m DX window, and should therefore only be used for intercontinental QSOs. For "local" QSOs, you should stay below 1.830 MHz. Likewise, 30m activity is better below 10.140 MHz than above, so as not to interfere with packet ststions, and on 12m, MFSK will probably be found close to 24.920 MHz. In all cases, listen first!
