Your answer to my email just like we are in ICQ or MSN chat.
Thanks for your very very good service.

Just to inform all who use Futaba T9CHP , my trainer cable for Futaba T9CHP arrived in hand of Thomas. I do hope we can use his system with Futaba.

just updated post #1 with more prices on each item I sell,
due to many people ask about this.
Now I drive and visit some Futaba owners to make more compatible tests :-)

How much is the 30 Watt amplifier ? Has anyone ever used the system with JR radios ?

just came back, can repport no problems with Futaba all tested versions
are listed on the web:
http://www.webx.dk/rc/uhf-link3/uhf-link3.htm

I also added a section about the PPM signal requrements I have,
please measure your JR radios and inform me if you think it should work,
all JR radios use same trainer plug ?
all with same pinout ? and all with same hardware behind the plug ?
and please try to give me a few type numbers so I can ask my club members for another test and measure night meeting if any one own such a JR radio :-)

About the 30W: it not for sale at the moment, too darn expensive !
but ok, if 7W will not take you where you want to go, then I think you should use a better antenna too, you see from 7W to 30W is only +7dB more power,
you need +10dB to get x 3 range improvement, so ok with 7W to 30W is possible to feel the range improvement, but a 10dB directional antenna is small and much cheaper.

I have some 30W power modules on stock too, so I can make a few boosters for sale,
they will NOT have isolator !! so it will most likely be fried if you opperate it with no antenna or really bad SWR, the modules cost a bit ! but I need a much larger heatsink, heawy = expensive postage too.

10KM record just broken

Using UHF 500mW system with 7W PA and Yagi antenna for video.

Have used the UHF 500mW system for some time new, works perfect - just remember to keep video receiver and 7W UHF transmitter LONG away from eith other > 10meter, or you will get into trouble!

btw.
The Futaba works fine with the UHF system,
but on mine Futaba FF7 there is a small SMD diode thats get VERY hot - when taking power from the Futaba trainer connector to the UHF system.
It will probaly die after some time..so you have to either put a much larger scotty diode in OR put a wire before the diode up to the + connector.
(remember to disconnect the + connector from the other circuit).

Looking forward to get the UHF receiver Thomas

Best Regards

Thomas,do you have any plans of building a (automatic) directional antenna that points continu towards the plane?

YES, many plans and also tried a few experiments,
but so far not much time assigned to this at the moment. so it is on hold right now.

>Has this been tested with the Futaba 10c ?
no not yet, but if this is the only thing that keep you from ordering ?
Then I am sure I can find a way to check it fr you :-)

Other people keep asking if this or that is compatible or not,
I have explained all about what is required to be compatible,
please measure a little bit your self and check, much easier.
again I will say: if you will order if I first check and prove compatible ?
then say it to me, and then explain me exactly what brand and type I need to get access to.
I can not go out and check 100 different systems just for your entertaintment,
please understand I try to spend as much time as possible, delivering systems to paying customers at the moment :-)

If you can link directly to the list where you have all the systems you Have tested it with, that will be enough. if it fits a 9c its going to work on a 10c, but i couldnt find the list that you reffered to

the list is on this page:
http://www.webx.dk/rc/uhf-link3/uhf-link3.htm

find this section:

The UHF RC TX unit is tested so far to work fine using:
Multiplex Royal Evo series 7/9/12 (5 pin DIN)
Futaba T7CAP (6 pin square)
Futaba FF7 (6 pin square)
Futaba T9CP (6 pin square) same as T9CHP

if you know the PPM system is hardware and software compatible 9C and 10C
then I see no reason why it should not work.
what contry are you from ?
The distance and location thing dont really work with your data ? :-)

OK just saw the full video clip loopforever made, wow 21 minutes of cool entertaintment.
10.5km flight away and back.
nice nice ! flight approved ! you have now won your self a free receiver !
it wil be posted asap !
the video text state you used yagi antenna, but that was only on the video link right ?
the RC uplink you used the short whip antenna and 7w booster right ?
please also inform us how did you place the booster, how hight and how far away from video receivers.
if you plan to go for the 15km record and win one more receiver ??
I suggest add your OSD and please use the 1/10 height rule of thumb,
so at 15km distance you should be 1500m up to achive optimal range like free line of sight, this apply both to RC range and Video range.

Yep I am one of the other people who have already asked if it is compatible with the Futaba 9ZAP, with no answer yet.

Ok, I did some poking around with a volt meter and with the transmitter turned on. Please reference the picture I attached as it represents the plug on the 9ZAP.
The shield is ground.
Pin 1 has 11.5v
Pin 2 has 2.15v
Pin 3 has no measureable voltage
Pin 4 has 11.8v
Pin 5 has no measureable voltage.

I have a trainer/dsc cable which reverses pin 2 and 3, I guess that follows the logic of out of one transmiter and into another.
I also have a plug used to check receiver battery voltage. This plug shorts pin 4 and 5 which causes the transmitter to turn on but remain off-air even when the on switch is off.

I am in the USA and I am not going to send you my only trainer cord half way round the globe. However, you should be able to find this plug locally very easily as it is common.

This is all the measuring I can do on my own, unless you know of something else I can do with a voltmeter. Not everyone owns or has access to a nice spectrum analyzer or oscilloscope let alone know how to use or read graphs produced by one. I certainly don't.

Fair enough, but besides compatibility with a 9Z is it going to work in real life with a 900mhz video transmitter of 500mw output?

So I will take you up on your offer, if you will actually test your system on a 9Z to see that it works and test it with 900mhz video to see that it does not cause video interference or rc interference then I will promise to buy the starter kit and 7w booster.

BTW I live in the USA and am also a HAM operator.

too bad in Italy (my country) 433 & 444Mhz are reserved for the Ministry of Defense... better not to use it ... Is this system available also in other frequencies?
