[Lowfer] TAG

[Garry Hess]

Andy's report of TAG reception spurred me to look last night too. 
Haven't done that for quite some time. Now I'm using an e-probe and 
SDR-IQ compared to a 10' loop and IC706MKIIG last year. The 66 MHz clock 
was calibrated by looking at a 10 MHz signal locked to GPS, then the PC 
sampling rate was set with the Wolf frequency measurement feature to 
give the exact, known audio frequency for a GPS-locked 100 kHz input. It 
wasn't nearly as easy as Andy's decode, but TAG was finally identified 
at 0541Z.

No New England NDBs were checked, but after the decode it was seen that 
FN42 stations WD2XSH/17 and /37 on 502.4 kHz WSPR were of their usual 
strength - the best being -16 dB SNR referenced to 2.5 kHz bandwidth 
from 2 W ERP (a legal lowfer is doing very well if it produces 1mW ERP). 
Don't usually see the QRSS30-rate transmissions of the WM lowfers here 
even under the best winter conditions so TAG provided another impressive 
indication of the sensitivity of the Wolf10 transmission mode.
