Guys.
This is just to help keep people informed. I have had a glitch in
my microair transponder that had me baffled ( not to hard to do). I am in
the middle of doing an annual on N357CJ and the trandsponder was one of
the items on my to do list. The following is the response I got from the
factory today.
For the time being I will most likely avoid large airspaces. When
my coverage went out on the trip to Beakley WV the controller would
have only had my last position heading and speed to find me if something
went wrong and I was a long way from anything at the time.
Follow up on a thread from Larry Fleshner last fall about ELT
batteries. I replaced mine today and checked the voltage of the old vs.
the new. After exactly 1 year the old ones ranged from 1.52 v to 1.56 and
the new were all 1.6 v. Just shows that there is drainage and though
these were in good shape I would risk another year to save $5.

Hi Joseph,
you unfortunately have been caught in the middle of major changes in the
industry.
Apart from the fact that we are always "upgrading/improving" our units,
there has been a environmental change with respect to Mode S.
At the end of this email I have attached a statement that is found on our
website which helps explain the situation.
The end result is that you probably require the Service Bulletin upgrade.
We have not had the CASA approval come through yet - we are dependant on
this approval.
On receipt thereof Service Centres around the world will be able to
perform the upgrade (we do have to get the required parts to them also).
This information will educate a little but for the immediate there is not
a lot of assistance available. As soon as we have the SB approval we
will let everyone know via the website.

Over the past 6 months Microair has received reports of intermittent
operation of T2000SFL Transponder, and in particular poor Mode C
response.
Microair has analysed these reports and the operational issues seem to be
associated with areas in which radar sites capable of Mode S are
operating.
Microair has decided to publish a Service Bulletin which will require
operators of T2000SFLÂ’s to have their transponders upgraded if they are
operating in Mode S environment.
This Service Bulletin must receive the approval of CASA before it can be
released.
The Service Bulletin will require the replacement of an existing circuit
board and the installation of an additional digital filter. It should
be possible for your local Service Provider to embody this Service
Bulletin.
Please check regularly with this website for more details regarding this
pending Service Bulletin.
