A friend recently posed this question to me.

Since there are builders here who know far more about tank coils than me, I,
yield to the experts.

Subject: determining frequency of a transmitter?



recently I purchased a transmitter--home brew.  There is no designation of
what frequency band it operates.  It is a plate modulated 807, crystal
control (oscillator tube missing).  The output tank has some rather small
tuning capacitors and a air wound coil about an inch in diameter and maybe
eight turns at about half inch spacing with a tap a couple turns from one
end.

Any ideas?  Thanks
