Hue, Different Mike on the hamfest reports.

On the ER65, I appreciate the reports that are coming in on it, both on and off list.

One other interesting thing about this radio is that the ECH21 tubes each contain a triode and a pentagrid converter in the same envelope, so it is really a 4-tube radio: Untuned RF amp followed by the regenerative detector, and then 2 stages of audio amp.

Mike, W6MAB

  RF,  THANK YOU for your hamfest reports, I love reading your reports!
  I will probably never attend a hamfest that size, so they're very 
  interesting to me.
  Say, how did the show's ARR-15 and BC-342 prices get reversed?

  Now re the ER65 receiver, that voltage is a new one to me.  It's not
  12, 32, or 120 DC.  Maybe you could contact Bengt Falkenberg,
  whose ER65 is on the RadioMuseum pages?
  I guessed the date about the same, judging by the one "Made
  in Germany" capacitor I saw.

  Looking thru old marine radio manuals, I have seen plenty of examples
  of simple circuit, but this is the most elementary marine product,
  overall, I have ever seen, I mean, considering the circuit and the 
  mechanics together.
