Re: BJ stability



I can't even remember my first CW operations as a novice, without a sidetone (but I still have the QSLs).  My second setup used an HW16, which has a sidetone (as every rig I have built and used perhaps since then). 

If you called this op who said your frequency was a bit low -- keep this in mind: the receive passband on a BJ is very wide compared to most anyone's receiver.  your ability to put your transmitter and receiver on same pitch is how well you match them by ear. 

I suspect all is well with your BJ. 

I imagine someone will post how to homebrew a sidetone in the BJ.  the rival Para80Set has both sidetone and electronic TR switching - so its a bit modern in these features!  Its a smaller board and isn't set up to be a front panel -- so guess what I have some drilling to do to get this thing put into a box. 

note a sidetone circuit can operate in parallel if you don't insist it come through your headphones.  I am a bit surprised they did not leave space on the board for sidetone circuitry, but needless to say it should fit easily inside the hobby lobby box.

I did have one contact that said my frequency was a little low when I first called him but then was stable for the rest of the QSO.  He said my transmit frequency was right on, same as I had determined here at home.  I haven't had any other comments.

I do find the lack of a side tone to be very handicapping since my CW skill is poor.  I tried another small receiver near to the rig and that does help.
