Not sure who should get this so I'm sending it to both of you. These prices are based on averages from eBay, Google shopping tab, or similar. They are also based on asking price as I didn't find any sold pricing, and some didn't have enough info (i.e. Micronta
SWR & Power Meter... VHF/UHF or VHF/UHF/HF, single meter reading or multi meter reading).
The "Home brew crystal controlled transmitter"... No idea how to place a value on that.
