. Receiver is a Grundig YB 400PE. I'm very new to SW (4 days ?) ; I'm a
sailor needing weatherfax and voice weather at sea.
I used the list of USCG stations at the bottom of the page, and the
jvcomm32 weatherfax program and got nothing ( the program seems fine, and
communicated to the computer OK) I just ended up with junk pictures. I also
cant pick up voice weather on listed stations. I can get foreign stations in
the 49 meter band , so the Grundig seems to work -

Some questions - I read that I'm to "tune radio to 4608.1 kHz" for a
4610.0 kHz station, but I cant get the Grundig to go to a decimal frequency.
Am I right in assuming I'm to use the fine tuning made possible by the SSB
switch ?

Am I overly optimistic in assuming I should be able to get Boston easily
from Long Island New York ?

Any pointers greatly appreciated -

snip

I have used the YB400 to receive WEFAX with good results; use software that
provides a tuning adjustment with a graphical spectrum display -- I have used
WXSAT and MULTIPSK on Windows 2000. You may also need to tweak the clock
frequency by single Hertz increments in these programs to deskew the output
and synchronizing the start-of-scan can be a problem but you should get
useful charts regardless.

I suggest setting the SSB tuning pot on the YB400 to the center of its range
and tuning the receiver with its keypad while monitoring in the WEFAX software
until the signal is within range of the tuning display; then fine tune using
the program's controls.
