Hi
Just a brief comment - you MAY still have a drift problem; or perhaps
I should say "hand capacity" problem - which is shifting the
frequency of the transmitter when you are touching the aerial.
You may need to try tuning receiver when you are NOT touching the
aerial.
If that doesn't help, you could use a "counterpoise" in place of an
earth - ie connect an 8 foot wire to the earth side of the circuit and
drape it along the floor (this will probably mean just connecting it
the the -ve side of the battery).
Something else that may help is to use the HIGH end of the band (near
1500 kHz) - the short aerial will be more efficient.
Otherwise simply use 20 feet of wire for an aerial as high around the
wall in the room as possible. (Very THIN wire will be fine).
It is also possible that the polarisation is incorrect. Try turning
the radio so that the rod aerial is vertical. It may be that when you
touch the aerial you are adding a horizontal component to the
transmission.
Well that's enough to try!
