Single Conversion RX with 9C/9Z
OK... So I thought I was getting a great deal @ $20 on flea-Bay and I got took. :-p LOL
I ended up with a "single conversion" x-channel Futaba RX with no crystal. I have a 9ZAP (primary TX/synthesized) and a 9CHP (backup TX with a Hitec Spectra). I figure I'm already stuck with this RX so I might as well use it on something; maybe a SPAD or summin'. Anyway; I've finally run across an auction for a SET of "single conversion" crystals on eBay BUT I'm curious whether the single-conversion RX with appropriate crystal (I learned the hard way that a "normal" crystal won't work! LOL) will fcn with my two radios. There's obviously?? a reason there's a single conversion crystal for the TX in the auction too?
If it will work, what are the pitfalls of actually getting some usage out of this? I don't need/expect a doctoral thesis on single v. double conversion just need to know if single conversion is relatively "safe" to use. I'm sure it was around long before the double-conversion stuff so logic would dictate that it's OK just not as "good" handling errors and glitches. Is that about it?
Thanks in advance friends. :-)
(Sorry for the double-post but maybe I can get an answer here quicker. Maybe this wasn't appropriate for the manufacturer's support forum anyway.)
