Your best option to make it on budget might be to use cell phone data: NTRIP.
A RaspberryPi 3 or 4 can be used as a NTRIP caster at base. Free android Lefebure NRIP client and BT-serial dongle hooked to TMX in tractor (=rover).
Google: eringerli NTRIP....
Or use a Windows PC running UseSnip Lite (free version with limited functionality) caster at base. Very easy! Very good!
For Trimble to do RTK you have add the antenna descriptor message RTCM 1008 the the correction stream. (A little bit tricky for first timers.)
The Eringerli RasperryPi way has it solved internally as a configuration option. No GUI - but it just makes you good to learn some basic linux command line stuff.. I mainly used copy - paste...
On SNIP -caster to get the RTCM 1008 message to the stream you have to:
A) buy licence for Basic version (some § 800) to use all the fine extra features...
B) solve it with software (RtkLib strsvr the latest release might be OK) or
C) by hardware + software (adruino uno running "inject 1008") in serial line between the receiver and PC (could maybe be placed between rover BT-serial and TMX serial ports as well?).
Or maybe use the Rtk2Go.com free caster also might has the option to get this add 1008 done. I'm not sure as I don't use it. Go find out!
But - anyways - it i a very popular free public "cloud" caster.
And for sure there are many other ways of getting NTRIP done. These are just the ones I use or have played around with.
Also note: Is your TMX unlocked to RTK? If it is not I do not recommend showing the unlock invoice to your Mrs unless you are on row crops or high value vegetables.
The reasonably priced Range Point RTX is not all that bad for small grain and grassland operations...
But then again: Comparing the more expensive Center Point RTX to owning a RTK base gives a more reasonable pay back time for all the additional one time extra costs...
