ACOMS crystals compatible with FUTABA?????

Recommended Posts

Hi there

I have a whole bunch of crystals for Tamiya ACOMS radio that I want to sell. I was wondering if they would fit on Futaba radio equipment. I remember the ACOMS radio were quite like the Futaba ones. Thanks for any help.

As long as they are 27Mhz AM you will be fine. 40am should be OK too, it only realy matters with FM channels, where the crystal needs to match the transmitter.

My experience with AM crystals is that your radio is a little bit more sentitive for disturbances, if you mix them from different suppliers.

As far as I know the most important is not to mix Rx with Tx crystals, AM with FM and different frequencies i.e. 40MHz with 75Mhz...

Confirm:- AM xtals are all interchageable, if they are of the same frequency.

TX & RX xtals of 1 pair are of DIFFERENT frequencies, so they cannot be swapped without detuning your set (ie you'll be transmitting on the RX's different frequency).

FM xtals are a whole different breed, as there's also Single & Double conversion to take into account... best to stick with same brand.

Haven't seen any Acoms FM sets, so dare say you'll be fine.
