I have just recently received my EzUHF (459MHz) system from Simon but have a few questions adn wonder if someone that has the system can help?
Using the RCImmersionTools application, I am able to make connection with the diversity receiver and wish to set channel 8 as my RSSI output, but am worried what effect the frequency band setting will have, as 459MHz is not in the list only the following:
431-433MHz
433-435MHz
435-537MHz
436-438MHz
Also, regarding the Tx, is 100mW its output on the Hi setting and a lower output on Lo?
Any thoughts?
I think I have found my answer in the depths of the Immersion RC website. Answer is to basically ignore those frequency settings.
Yes - ignore those settings (assuming you have put the 459MHz firmware on - all EzUHFs ship with 433MHz and you have to change it yourself).
High power is 100mW, low power is a little less - somewhere around 81mW from memory. Its best to fly on low power and then you can increase it in an emergency.
All the best
Simon
Many thanks Simon - I just assumed that they were pre-programmed. Shall give this a go now.
Cheers,
Tim
OK - cool. Here's the second bullet point from our website with the link to the firmware:
433MHz operation with standard firmware - UK customers can download the special UK firmware here: http://www.immersionrc.com/EzUHF.htm (http://www.immersionrc.com/EzUHF.htm) which changes the EzUHF to work on 459MHz at 100mW (459MHz is a licence free band reserved for model control)
The software will still list:
431-433MHz
433-435MHz
435-537MHz
436-438MHz
As you discovered before.
All the best
Simon
Another ezuhf question, can they be reflashed back to 433 and back to original 500mW

Yes it can 6lennn, just use the immersiontools software :)
J
cool beans, would be nice to have the option for that higher power if I get the chance to go somewhere its legal
might have to invest in some antennas ( just in case)
:whistle:
I'm thinking the same 6lennn, but will probably make my own after seeing how simple they are in design.

Yes flash them back and forth between 433MHz and 459MHz as many times as you like! Just swap the antennas at the same time for best performance.
Simon, I am looking at the two ezUHF systems you have and I have no idea what I need.
My TX is a Futaba 35MHz C7 and I will not be flying in the UK with it, so I want the maximum range it can give me and the necessary antennas.
This (http://www.firstpersonview.co.uk/index.php?main_page=product_bundle_info&cPath=60_61&products_id=401) one mark
Max range and all Antennas with a diversity rx
bob on!
Cheers!
How does the RMILEC compare to the ezUHF? If I see this correctly, thats a Foxtech UHF system, rigfht?

1 - 2 watt power settings ! No idea I've not heard of anyone using it. The only one other UHF that I have seen that is as trouble free as EZUHF is Thomas's TLRS. Dragonlink has sorted its issues out as well and Chainlink. But all of them including RCMILEC won't be UK legal.
I was only looking into using UHF outside of the UK. For my use, 35MHz is fine for the UK.

I noticed that the Foxtech site says "Hardware frequency Range 400MHz to 470MHz" but two channels: 415 and 433 MHz, shame they don't have a third channel at 459MHz.
I know this is a very old topic but, will the performance of the rmilec UHF be reduced due to the interference/other transmissions here in the UK?
James
When pu flash this to 459 does it also automatically reduce the output to 100mw also, keeping it legal in the uk, or could in theory you have it on 459 but still transmitting ata higherpower setting?
Cheers
Colt
It automatically sets the output power to 100mW.
Handy i guess
Im sure that I saw ssassen mention that on the UK firmware the power switch has no effect.
Can anyone confirm or deny this?

Anthony told me that it does have an effect. About 80mW in Low and 100mW in high from memory.

Hi Folks,
Hypothetically, what sort of line of sight range, would be expected from a 100mW ezUHF system operating on 459MHz? I'm looking into the possibility of going a bit further out than a 2.4GHz link (Jeti) can go at the moment.....
Andy
You should be getting past 8km without issues
Blimey, I didn't think it would go that far! Is that with the standard aerials, like those that Simon at firstpersonview sells as a bundle?
Yes that`s with 459mhz stock antennas
Question on the EZUHF 4ch Tx, I received mine this morning but cant find the firmware for the UK band, I've downloaded all the firmware from the immersion site and have done the tx and my 8ch rx to the UK firmware but there doesn't seem to be a 4ch firmware, anyone know where to get the 4ch firmware??
the firmware package has the 4ch.fw and 4ch_5-8.fw but no UK version all other firmwares for tx & rx's have UK specific ones with appropriate firmware with xxxUK.fw but nothing for 4ch??
Hi Rudeboy,
I'll bring this up with ImmersionRC immediately and come back to you.
All the best
Simon
Cheers simon, much appreciated.
Just a note its the Uk version of the 4ch_5-8.fw i need so i can use the rx in PPM to output the 8 channels!!
Spoke with sander and he says UK firmware for the 4ch isn't available yet!!! he's hoping to have it out by next week!! guess I'll be using the other firmware till then ;-)
Hi Folks,
I've just managed to pick up an EzUHF setup on Ebay, and I was wondering if there are any other Multiplex TX owners that have used their tx with this radio system?

Small world ;)
I posted it Special Delivery about 30 minutes ago so it 'should' be with you in the morning :)
Cheers Dave, I was going to ask if you were on here! Thanks for posting it out so quickly, if the weather plays ball, I may even get to try it out at the weekend!
Andy
Give me a shout on here if you get stuck with anything, but its ready to roll out of the box :)
Just pay extra special attention to attaching the servo/ubec leads as the pins are totall exposed and its possible to connect them around the wrong way or off by one pin (which would be very bad).
When you build your PPM lead double check everything you wouldnt want to put 12v up the PPM feed :D
Also never fire up the TX without the antenna fitted, it will slowly cook its self.
Fanstastic, thanks.
Speaking of wiring errors, I caught on on my TBS Discovery last night. For some reason I had randomly inserted one servo plug into a header (exposed like on the EzUHF rx) the opposite way around to the other 7. I have no idea why I missed it first time round, I guess my mind wandered!
I've just been reading the EzUHF manual off the website, and it mentions an Aux Ctrl port. I don't suppose you know what that is, the manual is a bit sketchy in that respect!
Andy
There is a USB port for Firmware/settings/diagnostics and a port for plugging into the EzOSD so you can read RSSI etc.
