RE: Some early digital proportional history
The thing I have against the R114 is that it is only four channels.
I tested my F&M transmitter on it and verified that the first channel is actually dead (unused). That means I really need a six channel Rx.
The R114 decoder could be modified for additional channels, but it's not a real easy task....a bit of a hack. I presume from what you say, Russ, the HPI is the same.
It would be really nice to have a good dual conversion 6-8 channel 27mHz receiver. I had hoped Silvertone would have one, but even theirs is single conversion and a bit pricey.

.....Edit: Maybe not that bad, though. My calculations put the price at around $112 American, and they do claim 10kHz bandwidth.
