6.739.7 Phonetics Station
 

What sort of radio would one need to determine to the tenth of a kHz
what frequency a transmitter is on? I imagine one with a graphic
display... so you can pinpoint the highest point of the bell curve. Or
at least a functional S-meter like on the Kenwood R-1000?
(http://www.rigpix.com/kenwood/r1000.htm) It seems that with a standard
portable receiver (like my DE1103), it's nearly impossible to pinpoint
the frequency of most stations with any more precision than 2-3 kHz,
based only on the purity of the sound (the S meter on these is fairly
useless.)

What's the least-expensive receiver in this category? I'd love to get
deeper into monitoring of utility stations, though perhaps living in a
townhouse with nowhere to place an antenna will be a limiting factor.

I logged this about 3 weeks ago @ 08:15 UTC to about 08:30 UTC on USB.
Just a male voice transmitting a long series of phoenetics (alpha, bravo,
etc.) When signing off @ about 08:30 UTC, he said, "this concludes message
#69, end of transmission." Any ideas what this was?

EAM on 6739 (your radio is off frequency).

(Really should address to the shortwave newsgroup not the scanner one.)

Assuming the station is AM, you can put your radio in sideband and move
the VFO until no tone is heard (zero beat) Then your are tuned to the
center frequency, which can be read directly from the radio.

A Wellbrook loop works fine in a house, though it's expensive.

Thanks, will try that.
