Thanks Curt. I was just reading some other posts where someone mentioned that the harmonica on the other frequencies will be seen as a high swr on the meter. Sounds good to me, I¡¯ll wait for the filters. The transformers were put together nicely. Wires not shorted to tube or anything. I made a PTT from the uBitx buy using a octocoupler and wired it to the T/R on the raduino. ?

Hi Joe, I would wait until you get the filters and then see what your SWR is. ?It's been a while since I've had mine on the Bird 43 looking at forward and reflected power. ?It was OK from what I remember. ?Be sure that you solder those tubes for the transformers into the supports and thatcher's the tubes are not loose. ?That make help you also if you did not already do that.

I tested the filter set on the analyzer and it looked pretty good in it's respective bands. ?I've see better and I've definitely seen worse but they are more than usable. ?I use them with the Bitx40 and uBitx without the amp.
