HI:
I looks like the VCO is not locking up at 909. Did the radio work when you got it?

Thanks for the response Walt
I was told by one of the local 900 people
that all the gtx ht's would do 902-928
tx works fine below 905 and above 915
rx works 896-941
I was wondering if edited the *mdf file wrong
I can program anywhere rx tx
but no tx between 905-915
Thanks Mark

Then it seems that the vco will not lock up. I know that I have never seen one not lock up in the 902 and 927 part of the band. I have never tried them at 909. A good reason to change to 25MHz split!!!!!

I believe there is a new repeter going up soon
927/902 and that should solve the problem

Thanks again Mark
