Hello everyone,

I have a Grundig YB 400 Shortwave radio. It's now about 4 years old. I am
in New Hampshire in Northeast USA and in a reasonably flat valley. I live
in an Apartment building.

I get almost no stations on short wave..

I like the design (electronic) of the YB400 and recommend it for a variety
of uses; it should be a good performer for you. Have you taken it outside
and away from steel structures and noise sources (power lines, etc.) to
test its reception? Try tuning WWV on 10 Mhz during the day and 2.5 and
5 Mhz at night in an outdoor location (using the whip and/or the external
wire antenna); you should get solid copy from your QTH at this time of year.
If not, the radio likely needs repair.

Also, keep in mind that during this solar minimum, propagation is not
optimal on many bands and there are often few stations to hear, especially
if you have a high noise-floor in your location. Consult this N.G. and
shortwave interest mailing lists (e.g. Yahoo groups) for interesting
signal reports and try tuning those for additional tests.
