PAPA vMeeting, December 4 @ 10am

Email Rob at email@example.com for the PDF
The year 1974 saw the beginning of Sherwood Engineering, offering roofing filters and upgrade kits for the Drake R-4C.
In 1976, Rob started measuring receiver performance on dozens of radios, since reviews in QST did not correlate with actual on-air observations at crunch time in CW contests.
Receiver test data is now web based with 150 transceiver and receiver listings.
