I do recommend adding a momentary switch for SPOT even if you only operate SSB, as holding it will put the rig
into Fine Tune mode on SSB using Allard¡¯s sketch. You might also consider adding a third switch for TUNE (wired in
parallel with the CW key jack).
BTW I had a recent CW sked with a friend and I used my BITX40. He made a digital recording and emailed a clip to me.
I am pleasantly surprised at how good the BITX40 sounds on CW. The keying is a little bit hard but not
objectionable. The tone is very good with no clicks or chirps and I am not hearing any clipping of the first code element
in the audio recording. It really sounds quite nice.
As I mentioned in a previous post, I integrated a SOTABEams Laserbeam DSP audio filter module (~$US30) into
my rig which gives me a 2.4 kHz WIDE setting and a 300 hz NARROW setting and it drastically improves CW
reception on a busy band, while only adding 30ma to the current draw.
