quote ]hi ! # i have an icom 706mgkii and a kenwood #at-300. #does any one know if it is possible to make them work together?
if it is, what is the interface or wiring to accomplish this?
thank you for your time reading this topic.

your icom 706mgkii radio uses a 4-pin molex conenctor to interface with the icom ah-4 automatic tuner. the kewnood at-300 tuner uses a 6-pin jst connector. #so the physical connectors are only one issue (they are different and will not mate) - see additional reasons below.
the kenwood (at-300) and icom (ah-4) automatic tuners use different control protocols (e.g. speak different languages). #kenwood at-300 uses a bi-directional hand-shaking protocol on the ts and tt lines.
aa4pb builds icom radio interface converters for different tuners.
http://www.ham-kits.com/mainframe.htmaa4pb statement regarding your specific configuration - icom radio to a kenwood tuner:
the kenwood interface (tuner) requirement is sufficiently different from icom (tuner) so as to require the design of a completely different circuit.
at this time, there does not appear to be enough interest (other amateurs) in the kenwood interface to warrant the development of a separate product.
no further work is being done by me (aa4pb) on the kenwood interface, at this time.
vk1od is working on an interface for kenwood radios to use icom ah-4 tuners (not completed) - opposite configuraiton from what you are requesting.

http://home.comcast.net/~hamlakemn/ah4/ah4.htmhttp://home.comcast.net/~hamlakemn/ah4/ah4-manual-5.pdfeasiest solution would be to trade or sell the kenwood at-300 tuner and use proceeds ($$) for an appropriate icom tuner (such as ah-4) to your icom 706mgkii.
