Need to replace a bad relay in your HW-7 or HW-8?
Tired of the clank-clank-clank sound throwing off your sending?
Want to go QSK to hear between the characters?
Need a general purpose QRP T/R switch?
The HW-8-TR board may be the cure! This solid state replacement board was designed to drop right in place of the HW-7 & HW-8 relay.
Included on the board are transmit and receive LED’s which can be remotely mounted.
With this board and a few simple modifications (parts included) your HW rig can perform quiet operation with QSK.
