For these hamware tuners I can offer an alternative firmware:
- hamware AT-502 (only for those with maximum values for TRX=255, L=63 and ANT=255)
- hamware AT-515
- hamware AT-615B
- hamware AT-615U
The firmware supports the "current" version of the tuners / controllers. Please check with me before ordering, if you own a very old tuner / controller.
This new firmware supports CAT control of the tuner via a simple interface and a modified firmware. Currently these transceivers are supported:
- Kenwood Protokoll
- ELECRAFT K2/K3/KX2/KX3
- ICOM CI-V
- TenTec Orion
- YAESU FT-847, FT-991A, FT-890, FTDX-5000
The new firmware listens to the CAT output from the transceiver. Based on the received VFO-A data, the related memory is selected automatically in the controller. Manual operation is still supported as with the stock hamware firmware. Frequency sniffing via the BNC socket in the controller is no longer supported.
Some transceivers (K3, KX2, KX3, ICOM) have the option to transmit the VFO data on each change on the physical knobs other transeivers must be triggered by i.e. a log application running on a attached PC.
