HF radio weather info

I bought a kaito 1103 HF, SSB receiver and plan to use it with my laptop to get weather; fax, voice, and text info on a trip late this year to the Bahamas. I'm trying to get the bugs out at home (near Annapolis, Md.) and need some help. I'm using JVComm 32-1.4pre software, a PCMCIA card (not the earphone jack of the comp.) the external antenna that came with the receiver (about 25' of wire). I can get weather fax but not text or voice.
Frequencies I'm trying for voice are; 4426, 6195, 8764, 13089, and 17314 hz. I can't hear any voice on these freqs.
Text are; 8414, 12577, 16804, 22374 hz (these are adjusted for the 1.9khz shift and I understand are SSB) I get what I think is computer code but my software will not decode it.
I also tried Seatty software demo version which would give the same(similar?) computer code but this would not even produce a fax.

USCG frequencies for HF voice broadcasts are as you posted, except for the 6mHz's 6501, not 6195. These broadcasts eminate from NMN in Chesapeake VA. Pretty close to you, so you'll have best results on the 4 and 6mHz frequencies. All are USB. Note that these are scheduled broadcasts, not continuous ones like on VHF. You have to be listening at the right times. See the full schedule here: USCG HF Voice

Here's the schedule for the SITOR text broadcasts:
The Boston station, NMF, is your best bet. 6 & 8 mHz would be best. Again, these are scheduled broadcasts (4X per day).

Hope this helps.
