NEQRP ColorBurst Transmitter
Submitted by WQ1RP on August 19, 2006 - 20:40.
A number of club members have expressed interest in the original NE QRP colorburst transmitter (so named because of its use of the color burst crystal at 3.579 MHz), and in the "Colorburst Sprints" which were a common event back in the early '90s. The schematic, parts list, and layout are presented here. We have no plans (at this time) to offer a kit; however, parts for the transmitter should be easy to come by, and the transmitter is easy to construct. Perhaps another series of Colorburst Sprints are in our future!

79er Modifications?
I am about to get started on a 79er and wonder if anyone has recommended modifications to the schematic included here. A quick review of the 72 archive gave me a tx/rx switching scheme, but that's the only thing I've seen.
Anyone have a built unit that can be photographed for the NEQRP Gallery?
