Receavers

[rchambers]

hi
i need some education on receavers. first what is a narrow band single conversion receaver? i purchased a hitec HFS-03MT FM RECEAVER. i put my crystals in and won't work do i need different crystals? next question if i accidently cross the power lead to the receaver will it burn out?
Try to educate me on receavers because i'm having the worst luck with them, and buying them.
thanks

i have a futaba 3 pm with hi tech receaver, i'll have to get my book to be more precise.
i'll get more info tommorrow for you. thanks

ok heres the information the receaver is a futaba R133F 75mhz i sent it in and got a reply today said the ant wire was damaged and they tuned and adjusted want to charge $40.38 to repair. The radio is a 3PM FM magnum
T3PM digital proportional Futaba.

I can't find a R133F i suppose they don't make them anymore.

i purchased this one hitec HFS-03MT FM RECEAVER to replace it but won't work do i need narrow band crystals?

You may need to use HiTec crystals in the receiver module.

what do they mean single and double conversion crystals?

 

[hamz9561]

The single conversion, if I remember correctly, uses a single frequency multiple in the receiver. The double conversion uses two different frequency multiples. It's been quite a few years since I last talked this technical about radio stuff. So if I miss the mark, someone please let me know.

new question how do you test a crystal to see if bad? there should be a ohm's tolerence number i would think.
thanks

 

[hamz9561]

There is no reliable way to test for a bad crystal with the crystal itself. If you have another set of crystals, I would try those in place of the suspect crystals.

well first off... receiver has no a's in it....

 

[rchambers]

well thanks for the spelling test, so i suppose you know nothing about crystals just spelling.
