 |
|
Hi guys,
I’ve got a Yak 50, Russian registered with the original radio. This radio works fine but seems to have a very limited emission range (a few miles).Does anyone of you knows how it works ? There are two toggle buttons. The left one is for noise suppression, but I can’t figure out what the right one is for (it has the Russian word for “net” marked on it).
Since I’d liked to keep the plane as original as possible, I want to keep the radio and want to try boosting the emission power.
About the landings, it is indeed special. I only had some fifty hours on Pitts for tailwheel experience, but you certainly can’t land it like the Pitts. The Pitts is tailwheel-first. With the Yak 50 I always aim at doing threewheelers and indeed somewhat slower than 150 km/h : about 130, 135 but with a little bit of power as in a precautionary landing. I must admit that I avoid flying with a lot of crosswind. I keep doing touch and go’s in order to improve my landings (on a grass strip). Fortunately the Yak 50 won’t groundloop as easy as the Pitts (I think).
Before flying the 50, I performed some landings from the back seat of a 52 but the lessons on the 52 were particularly helpful to learn about the Russian technology, more than about the landings. So I agree with the others : try to get some tailwheel experience before flying the Yak 50, not because it ’s so difficult to land, but because you’re alone up there.

Mark,
Here’s a picture of the cockpit : everything in Russian as it came out of the Shakthy factory in 2002. The radio has five knobs : two radio buttons for the frequency (only 50 kHz separated); a volumeknob (bottom) and the two toggle buttons. My plane is in a hangar 100 miles from my home. I”ll try to have more data asap.
But thanks for your answer !

Jan's, I have two YAK-50's... one that is wrecked and is just used for parts, the other I flew. I am also an Avionics Rep for the Marine Corps and have done some repair on the Russian radios. Your description of the two toggle buttons confuses me. There are two adjustments on the front of the radio in a YAK-52, but not that I can remember on the YAK-50 radios. Can you describe the radio that you have? Is it all one piece? Is there a control head with a remote R/T ???
All of the radios I have dealt with have at least 5 watts of output power. That's unmodulated carrier power. Peak envelope power is of course about 4 times that. There are a few models that put out even more power than that! Regardless, with a good 5 watts, and a good antenna... I usually can achieve ranges over 80 miles. Before I would suspect the radio as being bad, I would pay particular attention to the coax line and the antenna. You need to borrow a good in-line wattmeter and make some checks on forward and reflected power, measured at the antenna AND at the back of the radio R/T itself. Anyway, try to tell me more about what you have if you can.
Best Regards,
Mark Bitterlich

OH BOY! I have never, EVER seen anything like THAT! You've sprung a new one on me! What year is your YAK-50? I have a 1974 Yak and a 1985 Yak, and NEITHER of them have anything that looks like that! Is the thing I am looking at in your cockpit the actual RADIO? Or is it just a control head with the actual radio being located someplace else? WOW... looks like something brand new that no one else has! I have seen all the YAK-52 models too, and again.. NOTHING like that.
I would not worry about replacing that radio with something else that is not "stock" because what you have in there now was never "stock" in a YAK-50 that I have ever seen or heard about.... and I have sat in about 10 or so YAK-50's.
I have some Russian friends... I will show the picture to them and see what they say.
Never-the-less, the recommendations I made about how to check the radio are still accurate.
Wow.... something NEW!
Take care, and good luck... I'll be glad to help if I can!
Mark

Where do I get one of them little Mag Compass on top of the dash of the Yak 50, like in the picture?
Anyone have one laying around?

Thanks for the recommendations, Mark!
I’ll check the antenna cable and the antenna. The antenna is quite oxidated. The Yak 50 is the 80-1807 used for 120 hours from september 1981 until september 1983 in St Petersburg. Then it was stored and in 2002 overhauled in the Shakthy factory. I am the second owner since. The former owner, a Swedish pilot, never changed a bit on the plane. In total the plane has 195 hours.

Ok Jan,
I have shown the picture to everyone I can think of and no one has seen one like it ... yet. I still have to ask Sergei Boriak and Vladimir Yastremski.
Mark
p.s. The rust on the antenna is no big deal.... but something wrong in the coax or a connector sure as heck would be. You really need to use an inline wattmeter.

Thanks to all of you for the info about the radio. This list really works !!!!
So it’s a standard Ziablik (thanks Richard). Since the radio is working fine but with a low output, I’ll follow Mark’s advise and check the power with a Wattmeter.
