I was looking at new SWR meters I have a dosy meter Tc4001 and It's not working like it should. Should I buy a Bird 43P big dollar$ would like peak reading and be able to check 4 watts to 500 watts. I also see the Dosy TC3001P three meters nice but modulation on a meter ?? or a nice ham radio meter like the DAIWA CN-801HP HF/VHF Bench Meter. this is my choice and looks the best as far as price and reliable ...
