Re: Question about ultralight and loops for MW
As you probably know, because of the response delay in the RSSI and S/N readings on the PL-380 digital display, simply watching the readings in unlikely to be of much benefit in peaking the inductively-coupled external loops. For casual DXing I've had good results listening carefully for an audio signal peak while slowly tuning the external loops, and then fine-tuning the peak (using the display's S/N reading) as the loop's frequency is carefully adjusted from that point.
For urgent DXpedition situations like a sunrise TP opening on an ocean beach (which may be in total darkness) I simply use a modified ICF-2010 SSB spotting receiver to find TP targets, then tune the external loop to light up the ICF-2010's LED signal display on that frequency. The external loop is then perfectly peaked to boost reception on the PL-380, which only needs to be brought within inductive coupling range for a huge DXing boost. The entire procedure can be done in total darkness, and provides great results.
