Hi ya,

How many of us still use 27 MHZs receivers and transmitters in our models?   With all the new 2.4 gear around?

I have just been going through transmitters checking batteries and charging them; and came across my old 27 MHZ transmitter and wondering if its worth keeping it and using it in a model?

Does anyone else use 27 MHZ still?

aye

A lot of us who build model subs still use 27mHz  radio...in fact, if I could find another Futaba M series radio, I'd go back to it.

Hi John
One of our racers still uses 27MHz.  Although very seldom, he does have the occasional break down (the radio, not him) although its usually a case of damp, broken connection or duff servo, rather than a fault with the radio itself.
Now that almost everyone has moved on to 40MHz or 2.4GHz, it has left loads of free "slots" on 27MHZ.  There is now little danger of anyone inadvertantly switching on, when on the same frequency.
Having said that, there are a huge number of "toys" on 27MHz, but these are usually so underpowered that they will not over-ride a decent r/c set. There is always a possibility though, as it depends on the respective distance of the transmitters from the model (model on other side of lake + small toy on other side of lake = problems).
The level of confidence in not having interference is a big factor in the move to 2.4GHz, plus the amount of computerised "adjustment" you can make electronically with the latest Tx's, making set-ups a doddle.
I would use the 27MHz set only if you have to!  There is a reason why no one is using it
Cheers
Danny

Stiil use 27MHZ in all our boats (me and boy) 
More people using 2.4 and 40MHZ, less chance for problems. Being a Luddite has its advantages 
Confess that my Fireboat uses 2.4 GHZ - only because I acquired it complete, and require the multi-channels.

Curiously, the only 'frequency' experiencing any issues at our Open Day last Sunday, was 2.4    No, I don't understand either.

Hi,
   One of the problems as I see it with both 27MHz and 2.4 Gig is the increasing use of wireless mice, keyboards and other gadgets on those frequencies. The channel seeking on 2.4 Ghz gear might not work very well if most of the channels are taken up with albeit weak signals from the above computer kit and the like. I do believe there is hope yet for the dedicated r/c bands 40MHz and 459MHz UHF (plus 35 MHz for aircraft of course).

computer peripherals like these have a max range of only about 10 feet not many lakes within 10 feet of houses

I still use my Ripmax / Futaba 2 channel "brick" in my tug built in the 1970's despite a sinking and major car accident that left parts of the tug way down the road!
A full set of crystals but very little need to change them now.

27mhz in stepsons white star and girls Robbe Katja
Mainly because they were lying around at the time

[davidjt]

i still use 27mh, taken me years to bye what i have, cant afford to keep up with  fashions. i say if it still works use it doing no harm

having seen the number of people who walk past me operating a model at a lake , then switch on their own model without first carrying out a frequency check , i only buy 2.4 ghz equipment now !

I believe bluetooth technology in mobile phones uses 2.4 ghz, I bet there were a lot of those in peoples pockets at your open day

Yep and all those smartphones with the wifi will be scanning for avaialble networks as well (unless they have switched it off)

It won't be long before boat show organisers will be asking spectators/visitors to switch off their mobiles just like they do at the snooker

have the CB radio users, gone the same way with differant frequency our are they still on 27mhz, as it sounds like this bluetooth is the same as cb radio caused interferance. only now mobile phone users cause problems with 2.4 ?

Now there's a blast from the past!.... Anyone still have one?

CB, being a passing fad for most, has largely died a natural death.  The attraction of being able to transmit at high cost almost as far as the horizon waned when yuppiephones and the cell network appeared.  
I don't get any problems trying 2.4GHz when testing at home, and the neighbourhood is pretty well packed with networks working in that band, so passing cellphones shouldn't be a problem, bluetooth, being very short range, even less so.  Some details at  http://en.wikipedia.org/wiki/ISM_band .  The difference is that cellphones and wifi networks work to a standard that is not user tweakable - with CB there was always the possibility and therefore temptation to add a burner to convert a low quality low power signal into a high power low quality signal.

[Circlip]

C/B were allocated 27 moggies FM sadly, this was done after the market had become saturated with illegal 27 A/M sets. Problems arose when some idiots discovered that they could disrupt our toys by transmitting while we played. Further agravated by some loonies who found "If you go to a model shop and buy some crystals and replace the one in the transmitter, a whole new range of "Free" channels are available".

  Still have a legal Uniden mobile that the kids bought me one distant birthday.

All the old 27mhz kit was 2-channel AM stuff, which I have little use for these days. My dad still uses a set or two in a couple of his boats. Moved over to 40mhz and adapted those to 2.4ghz dual use a couple of years ago.

I only bother with 40mhz because 2.4ghz doesn't work underwater.

There were an awful lot of really good quality, multi channel 27mHz radios available back then...like I said earlier, Futaba made the M series which were virtually bomb proof as regards interference, there were also some real good radios made by Multiplex and Grundig. I remember having a six channel Grundig radio in one of my subs (my first X craft, I think it was). Graupner made the Varioprop series, more or less the top of the range back then.

I don't think it matters which frequency you use...27mHz, 40mHz, 2.4gHz...AM or FM, whatever you use, you will get interference at some time or other. There are just too many radio controlled 'things' out there nowadays.

Subculture..... Futaba also did 27meg M series in Fm I know cos i still have two sets

nice TX they did a boat /car version just converted one two 2.4ghz also two older Jr FM two channel sets being converted now
