Hi, Josh,

I am not an RF expert, so take ANYTHING I say with a large grain of salt.   
I was waiting for the real experts to chime in, but haven't seen any  
answers from them, so here goes ;)

The site you found and listed in your email looks good.  Thanks!

If you have a preamp for the band you want to play with [lets say 144  
MHz], you could make something VERY simple with just the preamp as the  
front end, a Minicircuits TUF-1 mixer, and an LO at 116 MHz.  If the  
preamp had selectivity, you wouldn't have a problem with the image  
frequency.  If needed, you could put additional simple gain stages before  
or after the TUF-1, but trying it without those would get you started.

Hope that helps.  I can't wait for the SoftRocks to arrive here!

Don't forget to play with Rocky!  http://www.dxatlas.com/rocky/

73,
