[ARC5] 4th Receiver Drift Test from KE6F Hallicrafters S38B

[D C _Mac_ Macdonald]

I never noticed any drift or instability on my Walter Ashe WAR-25 regen receiver. 
 
I still consider that it was a far better receiver on 80 and 40 than the S-38 
receiver I borrowed when the 6SN7GT tube died and I didn't have the money for 
a new tube! 
  
It had a potentiometer to control the regen level and when set correctly, it 
was definitely more selective than the S-38!

> To all on the S38B,  Since the S38 did stay withing a couple of KHz of the desired frequency for at least 15-30 minutes it had no problem staying with a typical AM BC or SW station to include WWV at 5 and 10 MHz, As noted, the short term stability was ok for CW as the IF bandwidth of the rascal is quite wide so the Wet Ware in my head was able to track the CW note as it danced around a bit.
