And this bullcrap coming from an AMA Leader-Admin, IP Instructor, Contest Director. NO IT DOESN'T HAVE TO BE UPGRADED to 2.4GHz. It's possible it has to be upgraded to 72MHz Narrow-band but that's a different story. 72MHz Narrow-band is still legal. Some clubs are trying to say it isn't so they don't have to keep around the frequency flags.
Kinda harsh response!
I still fly several old 72mhz systems. And have advised others in these forums about what it may take to get theirs back into service. Never said "
OMG, it must be 72MHz and has to be upgraded to 2.4GHz.". I did assume that a renovated TX probably has been updated to 2.4. That was a leap.
In this case, the OP apparently only has a receiver and is looking for a TX to run it with.
He'll have to buy the TX ($600, if from the other post). If he finds another much cheaper, he'll probably have to get it narrow banded. That means likely his RX will not work with it, so additional cost there. And as Cal Orr's site notes, there can be other issues - black wire disease, bad pots, etc. All of which would add to the renovation costs.
It can be done, and result in a very usable system. But it will be a labor of love finding the items and the service tech (if he's not into electronics) to get the work done. And all of that will be at a cost and lots of time. So in this case, it seems prudent to give it up, and consider a new system that "just works", so he can get on to flying....
