I've been reading about SDR dongles and I'm a bit lost. Are these primarily receive-only? It seems pretty expensive to get into the SHF bands. A transverter is spendy and the base station rigs that can do it are spendier. I can get up to 440 on the ICOM 706. I saw that some guys hack a Asus or Linksys router, but I'm guessing the range is pretty short. I thought about hacking a r/c car transmitter just to get a signal out. Not sure if that is doable. Would definitely need an amplifier but I've actually seen some plans for that, just not plans how to hack the controller. So--looking for a budget friendly way to get on the SHF bands. I'll probably find out no one uses them here so not wanting to shell out $400+ just to find that out. Wish I could find a budget kit out there, but no luck there either.
