We are still on a quest for one ( anyone ) who has
performed the Modifications for a Motorola P200LB / MT1000LB
to work in the 50 ~ 54 Mhz Band.
What we already know
1. A 42-50 Mhz Stock P200LB/MT1000LB will work up to about 52 Mhz, then goes out of lock.
2. Have been informed ( but not varified ) that the only one Laser
Trim Cap needs to be replaced. We suspect its the one furthest from the PC board.
Its been reported to be about 8 ~ 9 pf,
I have included a Photo of one that does work @ 52.525 Mhz, but
who ever did the work, did a very good job, and did not leave any
tell tail signs of ( any ) componets being changed
We Could Not remove the Trim Caps off the [ Source Radio ]
since it did not belong to us.....But was able to get a close up
photo of both the Modified 42-50 Mhz => 54 and a 36-42 Mhz
version just for evaluation
Anyone out there willing to share the Exact proceedure ? or will
we be left up to doing our own Experimentation?
Will be more than willing to offer surplus from the warehouse
for the proper information
