The TUNER program - TUNER.COM

-----------------------------

1. This is a tuning aid to help get a received tone exactly on 800.0 Hz.

It should accept COM2, COM3, COM4 command line parameters (default is COM1)

and report CLIPPING (audio signaltoo strong for the sigma-delta circuit).

2. Unfortunately it takes too many computing cycles to incorporate this

in COHERENT, so run TUNER first if necessary, using an 800 Hz sinewave

with no modulation on it (a steady carrier in other words).

It may be slightly useful on a carrier that is phase-modulated, but

the indicator will jump around trying to follow the modulation, and in

any event the useful frequency range would be limited.

3. The idea is to get the little yellow line centered between the 2 green

lines, and staying within the green lines at all times. The nominal

frequency is 800.0 Hz.

4. The range of this tuning indicator is 800 Hz plus or minus 20 Hz.

If your signal is not ALREADY tuned to within better than 20 Hz, this

indicator will be useless and quite likely confusing as hell!

5. There will be some rejection of other signals outside this range, but

if the signal you want is weak and the interfering signals are strong there

will no doubt be problems.

6. If you can hear the tone, there is no substitute for zero-beating it

with a good crystal-derived 800 Hz sinewave sidetone.

7. TUNERC.COM is for anyone who still uses CGA graphics - I slowed down

the update rate to accommodate sluggish LCD displays.
