Hello Ron,
My 53.41Mhz repeater here in Connecticut has been on the air for years
using a MASTRII conversion. I have had very few problems over the years
with this equipment. The Hamtronics that I have belongs to a club and I
was trying to help them get it up and operational. I think I will
Joe,
Would you be willing to send me the exciter for experimental modification?

I think I am coming to the realization that this transmitter strip might
end up on the shelf too. I've been trying to fix this for a local club
and I think I have finally given
It is more than possible you have a crystal cut on the wrong
mode. It's not hard to order replacement crystals although you
run into the min order or higher costs depending on where the
new rocks are ordered.
You might order and try both the oven and non-oven operation.
I run a TA51 6 Meter
Well...
The crystal could easily be the problem. Group member Sal
sent me a Uniden ARU-251 Repeater to re-crystal and align.
The crystal was cut on the wrong mode and a real
cluster $#* to the problem sort out.
The transmitter would partially align but not remain stable.
The sanity check

How?
I don't think he was having any trouble tuning it up, getting expected
power output, or having stability issues; he is only complaining about
proper modulation capability.

Sorry, but it does not belong to me or I would. This belongs to the
local club that I am helping out.

When you talk to them Joe, see if they would be willing to send the
exciter to me. I'd be willing to do some experimenting on it to see if
it could be FM'd satisfactorily.

I'm thinking that I might just have a bad crystal, but have no way to
prove it. The crystal does have the Hamtronics crystal oven on it, but
I don't think that should be the problem.
My opinion right now is that the TA51 6 meter version is just not a good
design and probably should be pulled
Good choice. I almost suggested it. Or an MVP/Exec II.

Joe, I bought 4 GE Mastr II 48 mHz exciters off Ebay
back during the summer for $1.25 each and they all
tuned up on the only xtal I had in the six meter band
- 53.4 mHz. They can be a bear to tune, so just be
patient if you come up with one of them to move into
the band.
It took me quite a

Hello to All,
I am presently working on a Hamtronics 6 meter repeater and am
finding it quite disappointing.
Sorry to read the above comment ... I've always had good luck
and a lot of great learning experiences with Hamtronics gear.
