MTX9000 VCO Modification
Posted: Mon Sep 26, 2016 1:08 am
Good morning!
I have an MTX9000 M3 in 900mhz (935~950) that I have pushed down in to the ham band with hex edited RSS. I am having problems getting the VCO to lock below about 904mhz (the band ends at 902mhz). This is important to me because of simplex and repeater inputs in that area. Is there a hardware modification that would allow me to re-tune the VCO to operate in this area? I'm looking for something similar to the Spectra mod for the 440 R2 radios that allows them to transmit in the R1 ham band.
Thanks!
