  • 72/75 MHZ going out of business? Nah!

    There seems to be a lot of hoo-ha on various forums regarding these frequencies being phased out by the major radio manufacturers.

    I've had discussions with my supplier and it looks like there is a limitless supply of radios in our submarine frequencies.

    Now if you'd like to stock up with a bunch of radios, be my guest, but I don't see US having a problem for years to come.

    What about 40 MHZ 36 MHZ - used by UK and Australia?

        yeah I know you have got them - but the dope we have here from importers is that 40MHZ and 36MHZ will be a thing of the past soon. So what is your supplier saying about non US freqs?

            It's the big three companies in the R/C business who are phasing out the lower frequency equipment- Futaba, Hitec, JR.

            Walk into any model shop now, and try and purchase a 40 or 35mhz set- they're just not stocking them now. Understandable, 2.4ghz is a much better bet for any other type of machine other than a submarine- no crystals, compact aerial, high rejection of interference, use it on what you like- aeroplane, car, boat etc. etc.

            So will you be able to get this stuff in the future? Yes I think so, but it will have a different label on it, and you will have to go to specific suppliers.

              Yes, you will, and our door is open and the 75/40mhz shingle is hung outside!

                Mike, I am wondering can you get other Frequencies?
                For those in Australia (and perhaps Uk) 40/41mhz I note seems to be now the default option for Radios via Robbe Futaba's excellent F16C and Graupner Radios, problem being I can see 40 getting full fast - meanwhile 36Mhz here and in the UK is still legal and somewhat underutilised (in Australia) yet we can't buy sets anymore on 36mhz.

                  35/36 mhz?

                  No problem. How many do you need? :-)

                    Its not how many I need, its whether or not you can get them. (At the moment I am fine). Sounds like you can and if so if you can advertise their specs and prices and I can pass that on to the guys. Another key consideration will be can you get Sombra Labs type RXs with them? Also, are these computer radios and how many channels? How much?
                    Thanks

                      It is actually. I don't buy these individually, but by the dozen and if only one or two are needed, then it won't happen as I don't want the dead stock.

                      As for the specs, look at the 6 & 8 ch radios I already have, its the same specs except for the crystals etc. http://www.caswellplating.com/models/transmitter.html



                      Sombra Labs have --
                      SL-8 EURO Version (Spring 2008)

                      No crystals, no glitches!. A low cost synthesized ultra-light, ultra-small 8-channel receiver with advanced DSP signal detection, noise control and glitch suppression algorithms. This is a fully programmable Rx that will offer many advanced features will now be available on European frequencies 35/36/40/41 MHz.

                        Looks good Mike, I'll let the guys know.
                        How much apx?
                        Also are there any problems with these Crystal free radios? Are they use PPM?
                        Thanks

                          hold on - something I don't understand...

                          If the Sombra Labs is just a RX and this is Synthesised (that is no crystal), how does that work with the 8 Ch WFly that has a Crystal?

                          Sorry but I thought you needed a Synthesised TX to work with a Synthesised RX????


                          Also for the 8 Channel radio, for the non stick channels (5 through 8), what are the TX controls (dials, 3 pos switches 2 pos switches)?

                          Thanks

                            POI, I onced used a Novak Synthesized 5 channel receiver with a Hitec Laser 6 radio which is a crystal based radio, and found that particular receiver worked just fine, actually it eliminated some servo glitching I had been experiencing at the time using a different receiver. Unlike a brushless ESC needing to be matched to a brushless motor. :biggrin:

                              John, the synthesizer replaces the crystal, and allows you to "synthesize" what ever frequency/channel you want. It isn't anything "special" between the two devices. However, the sombra labs RX in this case would be limited to "synthesizing" whatever frequency the crystal for the TX is.
