[Sort of Off Topic] Non-Ham Satellites of Interest
This is more of a curious question to anyone with some knowledge of non-ham satellites (I know about the NOAA satellites though). Are there any satellites that would be worth tracking at taking a listen to with an Arrow handheld antenna and a Yeasu VX-8R (HT with AM/FM modes). This is simply my curiosity of what's up there.

Hello Bryce and everyone here,
Try "satellite frequency uhf" with your favorite search engine. There is a lot of websites wich offer frequency lists, sometimes outdated. Many are around 250 / 280 MHz, something like that. First try a very easy, strong one, FORTE, on 401.568 MHz (+- 10 kHz of Doppler shift) with the tle : 1 24920U 97047A 13226.13396630 .00000147 00000-0 85928-4 0 9728 2 24920 069.9555 142.7308 0022573 185.2601 174.8286 14.25669016830080
It sounds like the FSK modulation 4800 bps of the european radiosondes, and as the frequecy is inside the 401 - 406 MHz radiosounding band this often fooled the radioamateurs. These last times there is no modulation, only a carrier, and FORTE looks like in a stdby mode. I listened the modulated carrier on may 16th, but at the beginning of june till now only an unmodulated carrier.
Try this one first. ;-)

Hello all I had a nice western pass of FORTE, 16 August 13 starting at 22:54z here in San Jose, California. Indeed, there is no modulation anymore. Here is my Doppler plot: https://www.dropbox.com/s/wkxddml712q9x4f/forte.jpg

Thanks all, I'm definitely going to have to try this one soon.
