I have an FT-736R and have just purchased MacDoppler from AMSAT. It will be installed in a MacBook running OS 10.13.6.
I’m shopping for a CAT cable to go between the two units. The guy at HRO said the original Yaesu cable to go with Macs has part# FIF-65A but I don’t see anything yet on Google by that moniker. He also said the Yaesu CAT cable for PCs is FIF-232C - which I DO see around.
Then I see a caution that there are lots of cheap cables around that use terrible chips that are a nightmare to keep running. The only cable I’ve found so far (on eBay) is $35 and the vendor doesn’t seem to admit which chip set is used. Amazon in the UK has a cable for sale for 16 GBP, which could be one of the cheaper ones.
Immediate questions:
- What subset of the alleged plethora of available cables is MacDoppler compatible with CAT on the FT-736R?
- Who sells such cables nowadays? So far I’ve found only eBay and Amazon; it’s not even clear they’re selling the same cable - never mind the one I must use...
