Heathkit
SB-104
104A HW-104
On the cutting edge of technology at the end of the 70's this Heathkit was one of the first all solid state full power HF transceiver. Many of these radios are still around in perfect to restorable condition. Except for the PA lots of boards and other parts are available.
Considering every 104 came with an extender board it is surprising the prices paid for extender boards.
This board is offered ready to use. Not a kit.
Satisfaction assured on all extender boards and kits offered. Any buyer can return the board within 30 days for a full refund of the purchase price. In fact even if the kit is built, and used for troubleshooting the set can be returned for a refund.
Price for the extender board is $60 plus $5 shipping and handling to the USA. $10 is the cost of shipping outside the USA.
SB-303
SB-313
Because of great sensitivity and stability the SB-303 ham and SB-313 SWL receivers are solid HF receivers that are still in demand.
I have been told original Heathkit extender boards are rare and difficult to find.

HR-1680
Many low power HF ham enthusiasts love the HR-1681/1680 transmitter/receiver pair. Good receiver to work full QSK with the matching transmitter.
Price for the extender board kit is $50 plus $5 shipping and handling to the USA. $10 is the cost of shipping outside the USA.

Cushman
CE-6 ect.
Cushman Service Monitors were what most all radio technicians wanted on their repair bench. All originally came with the necessary extender board but for folks that have a Cushman where the extender has become lost I offer a replacement here.
This extender has been tested in the model CE-6 service monitor. However the same extender has been part of other Cushman products.
Price for the extender board is $25 plus $4 shipping and handling to the USA. $8 is the cost of shipping outside the USA
