[Lowfer] Multiple ARGO runs

I'm passing along a comment from Paul, K5WMS that may be of interest to 
other Lowfer listeners. Paul notes that two copies of ARGO can be run 
simultaneously with the receiver tuned to a frequency whose audio output 
covers the frequencies of two different beacons. That way two beacons 
can be monitored simultaneously without the need of  SDR equipment.

For example, at my QTH beacons WMS (187.492 kHz) and WEB (189.95 kHz) 
are at approximately the same heading (this only matters if you use a 
directive antenna). Setting my IC-706MkIIG dial to 187.2 kHz USB allows 
both beacons to be copied after careful adjustment of the right-side 
frequency tab of each ARGO window (center at 292 Hz tone for WMS and 
2.75 kHz tone for WEB). The mode of each window need not be the same. I 
used QRSS-60 for WMS but QRSS-30 for WEB. Similarly, beacons WMS and CV 
(185.3 kHz) can be monitored by setting the radio dial to 185 kHz and 
adjusting the ARGO displayed frequency to center at 2.492 kHz and 300 
Hz, respectively. This was done last night and those three beacons came 
in fine.
