Thanks for your thoughts. It is difficult to see whether the bent plate has sections or not. The possibility of damage is the main reason I haven't already tried straightening it to see if there was any improvement. This VFO works backwards. Zero on the dial is the high frequency end, and 250 is the low frequency end. I've gone through the alignment procedure so everything is right at the dial edges. Unfortunately the WARC bands occupy the central portion of the dial, so it would be easy to transmit outside the low end of each band. There is an article in an ARRL QRP handbook, that mentions the HW-9 having poor dial accuracy. I'm at the point where I'll probably go ahead and carefully straighten the capacitor plate to see if it makes an improvement. If not, I'll then take the approach you suggested to re-bend the plate. 73, Fred K4DII |
