Re: [IRCA] TP's 09-04-08 (1737 activity)

Hi Kevin,
1737 KUT doesn't wander. It's a standard NDB with its 1737.0 carrier along 
with its +400 Hz modulated sideband that you tune to (1737.40 nominal) in 
order to hear it, in CW mode. With a receiver with SSB mode, you would tune 
to 1737.0 and select USB. If you happen to have a very narrow external audio 
filter, you'd tune to 1737.373 in CW mode. (Strictly speaking, the sideband 
does wander a little; I'm currently hearing it on 1737.370 the past week.)
In North America, almost all Canadian beacons use this same mode--a carrier 
with a +400 Hz modulated ident. Almost all US beacons use a carrier with a + 
and - nominal 1020 Hz modulated sidebands--you'd simply tune up or down 1 
kHz from the listed carrier frequency to hear the ident, in CW mode (not 
using a very narrow audio filter, but the regular CW IF filter in the 
radio).
French countries use a format consisting of only a keyed carrier--in that 
case you'd tune to the listed carrier frequency. Various South Pacific 
beacons associated with France also use this format--I heard one this 
morning, from Tahiti.
If you have a radio that only has AM mode, then you just tune to the listed 
beacon frequency.
Hope I haven't thoroughly confused you by now!  :)
Regards,
Steve
