Scherrer system, mentioned above is NOT UK legal (Scherrer only 433 to 440 MHz).

My vote goes to EZUHF - can be UK legal, wide selection of plug & play cables / leads to cameras available.

wgt40w,

And there's me thinking that my FULL Amateur Radio License that I've held for many many years allows me to transmit digitally on the 433 and 440 bands...... I must be wrong  :)

PK

You're totally legal to do that on the ground.. Not so legal from the air ;)

You'll find your license even covers you to transmit video on 1.3ghz but again not from the air :D

What ever way you skin this FPV cat its pretty much ALWAYS illegal.

Nice debate  :D

So people are suggesting EzUHF.  Do people have range issues with this as have been reported over on FPVLab or are they just not doing things right?

Primarily my UHF will be for an FPV wing flying with 2.4 Video, my quad, it may get UHF but at present it's flying 2.4 control with 5.8 Video.

I use Dragon Link. Bought both my systems v1.0 second hand and I've never had the slightest glitch. Good bargains to be found on eBay and sometimes here, or splash out and get a new v2.0 from The States.
This is not a game anymore!

I've personally never had a problem :) I LURRRVEEE my EzUHF.

I had an original Dragon Link system and it was glitchy as f--k but that was only because I was using Spektrum and the early DL's don't have a pre-amp. The later ones have a pre-amp so us Spektrum touting low-lifes can use them :)

IMHO the support offered by Immersion is better too, when I had my DL there was no 'DIY' firmware option, I had to post it back to the states where as an Ez has a USB port, same as TSLRS too I believe.

As mentioned in a previous post the TSLRS is supposed to be 'the rollsroyce' of long range systems but the price does reflect that :)

PK,
I don't think you can use your Amateur Radio ticket for R/C control on 70cm (or any band for that matter).
70cm telemetry from the model to operator is allowed though  (?)

Digital transmission ok,  and remote control ok (of beacons only ?... doesn't actually say 'remote control of beacons only') up to 500mW pep erp ?

Today I broke my personal record for most consecutive days lived

You say you're on 35MHz - why not just extend the antenna and GO! :D

So how/when/where do you send your unencrypted callsign then Paul?
I think it's a very grey area and I wouldn't want to be the UK test case!

It's a shame some of the 'best' systems are 'closed source' and not on 459MHz, that's why I'm persevering with OLRS as it's open source and totally configurable.

Devonian - I may be completely on the wrong tack, but - one of the features of an EZosd is:-

   "Periodic Amateur radio callsign broadcast, to comply with FCC regulations"
You learn something new every day.

Devonian

EZosd or EZUHF ?

I'm not sure either way as I don't own any EZxxx equipment (and it too is 'closed source').

OK, but the thread subject is 'Which UHF'

My preference is for EzUHf as it seems to offer more for the FPV pilot out of the box. Its got good support and relatively easy to adapt for our needs.

I also have a TSLRS V4 (same as holds the out and return record 117km or something)

Regardless of which you choose 90% of the performance comes from the operators knowledge on how to use the system and recognise its limitations.

EzUHF latest firmware allows variable frequency radios to be used i.e 8fg/12fg etc
External power jack allows a separate power supply simply
easily swap TX Antenna's
Uk frequency support
Additional matching products to maximise your enjoyment. EzOSD, Antenna tracker, phone tracking.
Designer is in the 'current' trends loop
Built in Spectrum Analiser
User upgradeable Firmwares without a degree.
Power boost function
Prefer the Rx Antenna designs


TSLRS
No legal frequency
Running an external battery compromises its failsafe capability
designer has not adapted the system for the benefit of FPV'ers but its become more geared towards a Commercial system
No OSD/TRackers etc
Rx Antenna uses a ground plane making it awkward for Multirotor use. RX uses push in connecters that allow the Antenna to twist
RSSI is iffy
Stuck with TX's BNC Antenna.
Min output is high at 500Mw but has 1W & 2 W boost
V6 versions Looks awesome
