« on: December 28, 2018, 0203 UTC »
Feel like a workout after Christmas? Weighing in at 46 kg (100 lbs), the Murphy B40 could be just the thing to get you fit…..or give you a coronary attack!  ;D

But look at all those knobs!

I saw one of these sitting on a table at a hamfest once. It was in rough shape. I thought it might have been a late 40's military transceiver? The wife of the guy who owned it was holding down the fort while he was off stuffing his face. All she could tell me was it was a military rig.

I asked Craig (the author of the article) if it was difficult to tune and what the sensitivity was like. His response:

Quite easy to tune, but you need to recalibrate the pointer to a reference frequency after band changes.

It’s not going to measure up to an NRD or Icom in the sensitivity stakes, but with a 10dB preamp ahead of it, It’s good enough for DX work.  Usual “warm” valve sound, and seems to ride over the noise OK.  I use it a lot, mainly for background listening.


Traveling Wave - Thanks for the YouTube link - most interesting!

LOL, yes, very nice, solid CLUNKING action on the band switch.  I like it.
