MX800
« on: April 25, 2019, 05:52:52 PM »

I have a modified Spectra Engineering MX800 repeater(OY6REA) , it's fitted with P2* modules for 450-485, the modification brings it to 432MHz.
Problem is that the front end keeps dying.
I have a bunch of these repeaters for 450-485MHz (and 1 modified and now non working for 432MHz).

Spectra Eng, could supply a repeater but it was some AUD$5000+, that's many many times the annual member fee income for my club.

Anyone know where i might find N2* (400-435MHz) modules for said repeater ?
a trade could maybe also be possible.

 
Best regards
Regin, OY1R.

After the modification did you retune the RX VCO to accomodate the change to 432Mhz ?
If not that would probably be why the front end keeps dying.
