How to identify Desktrac?

Post by spcamno »

I tried using the search function but can't seems to find the answer.

A friend of mine is shopping for a Desktrac to use as a repeater however afer some researching knowing that the Desktrac does make repeater and base station only.

I would like to know if someone knows how to identify them from the model number because since he will be shopping on the net and just want to make sure he find the right equipment not getting burned.

Thanks

I know there's a difference with the model number, I can't place it right now though, however... the repeater versions have two antenna jacks on the back, while the base stations have only one. Often the base station models don't have a fan in the back either.

So, model numbers aside, if you look for the antenna ports on the back, that'd be a good sign of a repeater.

Thanks Josh for your reply!

Yeah, that's what I was thinking too but since there isn't much info on the model number decode section I will like to know more because I have seen some with only one antenna port but with a fan at the back of the housing.

Not sure if someone tamper with the unit or not but if you ever have find those info on model number decoding please post.

Thanks again!

The rule of thumb on Motorola bandsplits is that you have to read
the unit to be certain of the bandsplit unless you are lucky enough
to have the original build sheet from the factory. (L = consolette,
first 4 is power level, second 4 is the UHF band.) You could also make
a pretty good guess if you found a unit that was set up on 453/458,
or 462/467. etc. for instance because you could be reasonably certain that its
full split was 438-470. A cheap frequency counter can be very useful
in situations such as this if you're not yet set up to program the unit.
