A refinement of that system would be to have the unit generate PCM / PWM synthesised speech, to be injected into the receiver audio path, so that it would audibly announce the current setting - similar to the way radios are often adapted for use by white-stick operators.

I don't think the average PIC has enough non-volatile / code memory to hold that much synth speech, through. The speech might have to be programmed into / held on a separate serial-access flash memory IC.

I'm regularly working over 100mi and last night copied F5ZSF beacon, a long way off.

I have tilted my beam up a bit to refract over the hills and it seems to have worked.

So, I call and call...get those rigs warm and let's hook up. I also call on CW but haven't yet had a CW QSO.

Good stuff. A real sense of achievement.

I wish the SSB activity around here was a bit more lively around these parts. Once I get my TR-9000 sorted I'm going to start looking at a better aerial. Current set up was really to get me back on air. Horizontal dipole in the loft. Actually works quite well.

I was thinking on stacked big wheel/cloverleaf to get round the rotator issue (trees in the way where that would go) and a bit of gain.
