Title: RC frequencies
Post by: Neil on July 16, 2018, 09:32:22 pm

can someone tell me please...……..76mhz and 80/85mhz frequencies, I believe, and marked as surface craft only on the boxes, are of USA origin, and this would tie in with the previous owners profession as a ships captain woring out of the US.


My question is are these set legal for use in the UK, as the 4 sets that I would be listing are brand new, but no good for sale if not legal over here.

thanks for that, but it doesn't tell me [unless I missed it somewhere] whether US sets of 76 and 85 MHz sets specifically for surface craft from the US  Can be used legally in the UK

The detail re legal frequencies - the button/link  "What frequencies are available"  (https://www.ofcom.org.uk/spectrum/radio-spectrum-and-the-law/licence-exempt-radio-use/licence-exempt-devices/Radio-controlled-models#accordion__target-85478)at the bottom of the page needs to be clicked to reveal detail listing

But the answer is they cannot be used in the UK legally

hi C-3PO...….Yes, many thanks......just been talking to Stan on the phone and sadly he has told me the same, and gawd knows where I got the 80/85 MHz from.....


I have 4 absolutely brand new never been out of their packaging sets, 3 x two channel sets at 76 MHz and even worse one spanking new 72mhz 4 channel [ for aircraft only] futaba attack...….these were to be sold to give the money to the RNLI in memory of my old friend Ken Gibson......he must have bought them when based in San Diego and San Francisco.


would the cost of conversion to 40meg be too costly and then sell on as I would feel criminal just dumping 4 brand new radio sets.
thanks for any advice guys.


cheers, neil.

I'm fairly certain that the 85 sets are used in countries such as Holland (Netherlands) and Germany. It might be that you could sell them there?

Just use them on Fleetwood boating lake. No one will know and I wont tell. Conversion would not be cost effective so its either use them or sell them on fleabay for what you can get for them.

72mhz is the North American Air Frequency for rc airplanes.75mhz is the North American ground frequency for rc cars and boats.
75mhz typically had channels numbered 60 - 90... so your transmitter may have been channel 80, or channel 85

Yes, please stick to the rules, they are quite reasonable.
It's safer for you and won't spoil it for the rest of us!   ok2

Apart from the legal issues, using a frequency not allocated for model use in this country runs the risk that a legal user in that band might interfere with your model.
MOD seem to have 72 and 75.

They might blat out a lot more power than our transmitters.
