[MRCA] Today's Moose & Squirrel Radio

[Al Klase]

RF Communications (later Harris) RF-301P



This is the "Portable" version of the better known RF-301. Covers 2-15 
MHz.  Does either sideband.  Weighs 23 pounds without battery, so you 
wouldn't want to hump it too far.

Like the RF-301, it's a hybrid set, transistors with tubes in the 
output.  It uses a 4604 driven by a 7906, for 50 Watts PEP or 20 Watts 
CW.  Both tube have rapid-heat filaments, so you have to suck an extra 
breath after PPT until you have output.

This thing uses  onobtanium Deutch audio connectors.  I managed to beg 
one form K4CHE, and built a breakout box to use more common accessories.



12 volts is available on the connector, so I installed a Plessy SL6270 
in the box to ensure adequate audio drive.  The is the IC used in the 
Transworld TW-100 radios.  It's described as a VOGAD, voice-operate 
gain-adjusting device.  I'd used these in another project, and found 
them quite effective.  You heard it on the air, so I guess it works.

Just so you know,
Al
