John, Good to hear you're thinking of reactivating lowfer TAG.

QRSS might be "old" but you don't even have to know Morse code to use 
it, just a lookup table to use at your leisure.

I especially enjoyed when TAG sent WOLF. That required very good 
receiver stability but had impressive sensitivity, Back when Loran-C was 
active you had a nice article on the internet explaining how to use its 
harmonics to accurately calibrate the frequency. More recently LOs 
locked to GPS have become commonplace.

Not sure if you could switch between QRSS at the watering hole and WOLF 
on a different frequency, but I've found such operation useful for the 
lowfer I've run now for a decade. It may not apply to you but in my case 
even though the beacon is 23 miles away it desenses my ability to copy 
other lowfers at the watering hole. So on a daily basis I move the 
lowfer away from the watering hole. I try to do something different each 
year. This year I'm sending wspr15, opera32, CW, and visual ID. Last 
year I initially sent EbNaut. That requires GPS stability on receive and 
soundcard sampling. Although not really that hard (see 
http://www.n1bug.com/lfmf/ebnaut/index.shtml) no one to my knowledge 
other than W1VD and K3RWR bothered to achieve that so I went back to 
wspr15 and opera32 , not that those modes have many fans either, hi. The 
new wsprx FST4W mode at T/R 1800 seconds will have impressive 
sensitivity and be trivial to use. I'll probably give it a try next year 
because of that.

Hope to copy TAG again soon.
