Those frequencies belong to WWV - a time station based in Colorado. Mike

Yup, WWV, Boulder, Colorado and WWVH, Hawaii. In the evening I get both signal on 5 and 10MHz, 20MHz has faded out, 2.5MHz just Hawaii fading in, 25MHz WWV during the day. Lots of useful propagation info and storm warnings....

Sometimes in the background on the same frequency is BPL in China and another in Argentina. The is also a Russian on 14.996kHz and CHU Canada on 2 other frequencies.

Yeah, 15-20 foot is not going to work all that well at 5 Mhz. You need to think a bit bigger - the 45 foot PAR that I mentioned in an earlier thread will work quite a bit better than a 15-20 foot wire vertical

hey i have a friend who just got an RTL SDR dongle and im trying to help him get the ofset tuned (so the freq diled in is the actual freq the dongel is tuned to. best to used a known narrow band signal for this he does not have the up convertor and the dongel only tunes down to about 25-30 mhz are there other time freqs like those in the 25-30 mhz and up?

No- this range is primarily used by CBers, hams and a few oddball utilities as well as some studio to transmitter links. WWV can be heard at times on 25 Mhz, when they have it on, and propagation allows it, but that's about it...

I think we have a 2 fold issue here - having a crummy antenna, and software issues. Some of these software packages have Yahoo groups for support - or you can try posting your software questions in our SDR forum...
