In using the Bird 43 outside the bandpass listed on the slug, I have found that the meter works very well for tuning an antenna for minimum SWR. The power readings on the meter are just not accurate when the frequency being measured is outside the slug bandwidth. I have not gone all the way down to HF to make a comparison, since I have some HF slugs, but the variety of VHF/UHF slugs I have work fine to tell me that something is wrong with an antenna or feedline, or even a Z Matcher adjustment when used out of band. You just can't record the power readings as actual. ===========
BTW I could use a 100W VHF and a 1000W 2-30MHz slug here in Brazil :) If someone has a spare willing to sell for a cheap price...Remember I'm a poor third worlder who lives with monkeys on street :oD Greetz :) Pu1BZZ Alexandre
