"When a radio is tuned for ONE Specific frequency, all the effort goes into that one frequency...


You said you tuned to 1000hz"

the radio was tune using a 1000hz tone


"So any sort of audio CLOSE to that freqoency of tone, will also pass thru easier than the LOWER tones or, in reality, any range of tones above and below that "tone tune" will not pass as well."


blah blah blah.


step #10 of the 148gtl transmitter alignment procedure.

148gtl, gtl/st and gtl nw/st, revision 1.111, 03/11/03 Burke


tx mode, channel 19 am mode dynamike maximum.


modulation meter to antenna input. insert 1KHZ., 50mV. signal to microphone input.


adjust VR501 AMC control for 90% modulation.



(adjust vr10 in am mode for 5.60vdc at the emitter of tr41)

switching out the 2SC1419 for a TIP41 is a waste of time.
