Spectra modification
Is it possible to modify a spectra to receive on 929 MHz ?
Assuming it's already a 900 MHz model (D27, D37, T27, T37), one resistor on the VCO, and hex-edit the programming software, program your frequencies, and you're all set.
There's info about this on http://www.repeater-builder.com in the Motorola area, Spectra section. Also http://www.batlabs.com in the model-specific area, Spectra section.

Yes I did check that website. It seems that the radio stops at 928 MHz. Do you think I can reach 929?
If you added a resistor to bring the VCO down to 927, try a different value to let it go to 929. The radio should normally receive 935-941, so perhaps it doesn't need the 220k resistor. Try a 330k or maybe a 470k, or try it with no resistor at all; it might go down there as-is once you've gotten the software to let you enter frequencies below 935.

I can program my 929 MHz freq with rss modification. However I got the fail 001 error (or something like that) but after resistor mod, everything works except for the audio control. I hear tones when pushing volume button but it does not affect the audio (very loud). I did not try this radio before modification so I don't know if it's due to the internal mod...
