Designed for the 27 Mhz CB band, these 100W Power/SWR/Field Strength Meters can be used on HF and maybe up to 50 Mhz with less accuracy.  Might be good for QRP.  Probably not useful on VHF and above. Asking $ 10 each. The top one in the photo has been sold. To see my other listings please follow this link: To see my other listings please follow this link: https://hamshack.ca/author/ve6tc/
