| Subject: | Re: Radio replacement |
I know of two Yak 52s where the installation of the TRIG TY91 was
problematic.
A lot of noise and several avionics specialists tried to figure out why
but were unsuccessful until now.
And yes, the installation was done by professionals.
All the precautions were taken, measurements done (SWR etc ).
The noise comes from the engine, thru the antenna, that has been
established with certainty.
But finding a solution is something else. Filters were applied on the
engine, no cure.
Only my 2 cents,
Jan

Had a dual head TY91 radio fitted in my -52 nine months back, replacing SPU-9 intercom
panels in each cockpit, and TS21 transponder replacing the Baklan.
Reused existing YAK antenna with new RF cable ... don't use the ADF so I believe
the splitter was removed.
Worked closely with my UK avionics guy (Andy Stevens - 40+ years experience) and
Trig on wiring loom design.
That integrates YAK audio alerts (G & Stall) to aux audio & brings all the data
connections to one D connector (front cockpit by starboard side external access
panel) to make it easier to add new kit comms in the future.
Took care in using recommended gauge power/data cabling and attention to manufacturer's
earthing / install guidelines - no engine noise issues at any stage.
I also designed some 3D printed mounts (Selective Laser Sintering) to optimise
the display viewing angle (up and left towards pilot) that enables the TY91/TS21
head units to directly mount in the panel without any alteration, just bolts
straight in.
At which point I'll declare an interest ... I'll be launching a web site in the
next few weeks where the mounting plates and other designs / services will become
available.
Bottom line - careful design and install has not caused any engine noise issues
in my -52 with Trig kit.

For a start, myself being NO electronics wizard I installed the Trig in the 18
T myself for 8.33 requirement in EU. We had a LOT of noise in the headsets when
NOT doing radio calls. The calls were clear all the time. All shielding of wires
and HT leads were saved as standard. In the end it was my mistake to hook
up the stall warning wire onto the mic input to the Trig that is very sensitive.
Now when I found out somehow and cut that joint and used the aux for the warnings
finally all is perfect and super clear radio comms and intercom via Trig.

Just to update my "losing air after start" problem, eventually, we found th
e problem to be a hole in my right brake expander tube. That was the last p
lace I would have guessed to be the problem because I have not heard of one
leaking. =C2-I replaced the whole brake assembly because of =C2-inter-
granular corrosion in one of the metal disc's. Thanks to Dennis , Doug, Cra

Thats what makes it so difficult.
Some have good experiences with Becker, others dont. Same with TRIG.
My point is only: even after having it installed according to the books,
works done by professionals using the correct cables and following the
manual in every nitty gritty detail, you can still have (a lot of)
problems.
Rob, you probably have a 52 that is less noisy than some others.

Guys,
I was supposed to share a air condition room at the college with Craig
Payne. Unfortunately because of engine problems (my bad) I did not think my
airplane would be ready in time for the show. I therefore went and
scheduled my self along with my two grandsons, to fly the B-24 for the Collings
folks. Can't back out of that now.
I had one guy who was going to take my place but he had to bail out because
of a medical problem. So far I have been unable to find someone to take
up my share of the room ($437.50 for the week) which is paid for. Soooo.
Looking for some one to take up all or part of.
It has taken a good many years to get to the point to get an AIRCONDITION
room at the school. Cheap transportation to and from the field. And
always good bunch of people around the beer joint. I am going to miss this ;-(

With a pre-war electrical system and unsuppressed relays everywhere I've yet to
find an electrically 'quiet' YAK-52 and the only concession to modernity in mine
is the automotive plug conversion :-)
Problems will primarily stem from one or other of an oversight in installation
and materials or a faulty (noisy) aircraft system.
I can certainly agree that any of these can be difficult to isolate but if they
were fundamental shortcomings in the kit (Trig, Becker etc) then everyone would
have similar problems, which is not the case.

My Flightline 760 works perfect in my 18T. No noise at all. I do have the auto
