TOPIC:

27mhz v 29mhz is one better than the other? Can you use a 27mhz crystal set in a 29mhz labelled tx+rx? and vice versa? If you use a 27mhz crystal set in a 29mhz labelled set what issues would you get?

All what I know is that
26 can be with 27 receiver and vis versa
and 40 and 41 mhz are ok.

No idea ... 72Mhz & 75Mhz are not licenced for RC use in the UK, although you do see them occasionally (eBay purchases from the USA I guess), 29MHz & 36MHz are also illegal in the UK but you just don't see them here (no one buying cars from Australia?).

I suspect it might work - but I'm pretty sure you'd also be throwing out all sorts of spurious signals, which might not endear you to other RC users in the area

Out of 27MHz & 29MHz, which is more popular in Oz? In the UK, before 2.4GHz, turning up with 27mhz equipment meant finding out what band everyone else was using, but if you had 40mhz gear, you might be the only one - in that case I guess there was some advantage to having 40MHz radios...

In France we had 26mhz, 41 mhz and rarelly 72mhz.
I think that the important is the tenth. class 20 class 40 and class 70.

Looks like you could switch the receivers but it wouldn't work great.
Something with filters and antenna length...

I got a 40MHz transmitter from Japan. The frequency in itself is legal here...
But the range is different (overlapping into unregulated at the lower end) and they are 0.05 MHz off.



Don't really care about that though...

Just thought I would share my source for replacement receiver aerial wire These days everyone would have a spare Ethernet cable lying around These cables are made up of 4 pairs of (normally) stranded wire and with the diameter of each wire being almost exactly the same as the originals they work perfectly

Andy, it remind me the work...
What is diameter you need?

no no this was just an idea for others to use

very interesting for use
