I have asked for advice and have gotten it, now I need a little more. I am semi-retired and farm a small irrigated acreage. So this is more a hobby than a full-time job.
I am trying to put together an RTK system that I can use for spraying and mowing and have been using WAAS which has been working fairly well. I have a couple of ez-guide 500's one is unlocked to RTK, the other isn't as well as a couple ez-steers. I also have an ez-boom going through a raven 440, all this works well with WAAS.

I have purchased a MS 750 with a zephyr antennae, and a Joey 900mhz radio. My issue is what to use for the MS-750 radio. I can find lots of Trimmcoms and Sitenet radios, but dont which to purchase. Trimble seems to have firmware to turn the Trimcoms into ag use. Here

Also I am having a hard time finding the correct cables, Trimble is showing a wiring diagram with a 38968-xx cable that looks like what I would need. but I can't find it. Found a few that look like it but seem very expensive. Also is there a good source for the firmware, I know the 750 is not supported anymore, but thought someone would know where I can find it. My local Trimble dealer is a Case-IH dealer, and I have been JD oriented most of my life so I havent tried them yet.

I know there are a lot of paid simpler options out there, but I really would like to put this together without spending a huge amoumt amd pay and annual fee.
