Chris ,
I have the welz 220 swr bridge , its good down to much less than 1
watt and the calibration is quite close , never pushed more than 20
watts through it , always take it out of cct once the system is tuned ..
The Bird meter has a coaxial dynamics 250 watt HF element , which reads
about 50 watts shy FSD , 250 indicated = 300 actual , its linear ,
I made a cal chart , reads down to watts at the low end .. I keep that
by the Tx

Hi Steve,
I found a lack of sensitivity with my 1.8 - 160MHz Welz SWR/PWR meter on
630m, so not much good for a few watts, probably OK with high power. I
found the best solution was to build one.
Chris, G4AYT.

Has anyone here had experience using (or attempting to use) an HF SWR
bridge on 630m and if so, what did you find out?
Thanks,
Steve
