I should be getting my MFJ-346 freq counter this Wednesday. I plan to use it in conjunction with my MFJ-207 swr analyzer to do a frequency sweep of the A99 with the Firestick FS99 and with the stock A99 top section and do a swr graph chart. I was surprised that with the Firestik I had to adjust the A99's tuning rings all the way to the top and the Firestik's adjusting screw all the way in it's tip.
