Looking for Micro Receiver on 75 Mhz
I have a young friend working on a tiny battlebot with a question. He needs a JR compatible 4 ch receiver on FM 75 mhz, I need to find out the specific frequency, it might be ground channel '4' whatever that means. The question is do the small receivers like the Micro Joule or Penta or JMP have oscillator sections that are compatible with 75 Mhz? The boy is very enthusiastic, so I'd like to help him out, he also has made some small R/C planes that are very nice.
Any help would be appreciated.

there is a JR R-700 receiver on 75MHZ available at,
Don't know wether u are looking for a micro receiver, thought this might help.
I don't think the JMPs etc. will work on 75 by just changing the crystals The L-C components in the oscillator ckt will have to be adjusted/changed for 75MHZ operation.
If done so the JMPs will be good even till 200MHZ!

The local oscillator circuit of the JMP 72 MHz will work at 75 MHz.
It is the input LC tank circuit which will have to be retuned for best sensitivity.
I can send you the simple procedure to do that.
For your information, the 35/36 MHz receivers only differ in the adjustment of the input tank circuit, and they work from 35.0 to over 36.5 MHz, so 72 to 75 is no problem for the "72 MHz" version.
Hope this helps.
