Default What kind of rx is this? Very odd.

In what turned out to be a bad online buy (8uhfs, rcver, crystal, module), the guy only sent the TX and Rx. Here is what I don't understand. The rx is a Futaba FP R148DF 8 channel micro FM rx. On the back is a silver sticker that says, "20KHz 1991 narrow band". What is that? Is that some european band? It was for a helicopter and has a wierd antenna on it as well. Short black and about the size of the ink tube on a bic pen. Can I use this rx? Does anyone want to trade me for a normal rx?

Default Khz VS Mhz

The 20 Khz refers to the spacing betweeen the frequencies, Mhz refers to the frequency. 1991 means is should be legal, The space between frequencies use to be as much as 80 Khz , over the years it was narrowed to 20, This is where Narrow band refers to. All radios must now meet the narrow band standards set in 1991. Yes it should be usable, it wouldn't hurt to have the whole thing sent in for a check up, Do a range check , if it checks fine it is probibly O.K. . The Ant. is a whip ant for Helis, I have never used one in a Airplane but it should work, I have seen guys go way up with Helis using the Whip ant without any problems.

Thanks man, it's nice to know I have an extra rx. It is disturbing to know that when I took this to my local hobby shop (Hobby Town USA) the head honcho airplane guy told me that this was some kind of ham/european rx that I could never use! Thanks again.

Hi Billy!

Sometimes the labelling can get confusing, even for dealers. And especially since factory antennas ARE color coded for bands, they could easily be confused by the rubber duck antenna.

This is a legal, US RX which is still sold. You can do a search of www.futabarc.com with R148DF in the search to help find more current data on this Rx (or similar other items that you're unclear if they are current, etc.)

The whip antenna is not recommended by Futaba.

8) Can I replace my antenna safely with an aftermarket "duck", "whip" or other antenna?
We can not recommend doing so. Making this modification to your transmitter is against FCC regulation (unless you are a HAM licensed technician) and may also void your AMA insurance coverage. We do not recommend them for receivers as they have been tested and determined to produce a lessened range.

For more info on antennas, feel free to send an email to

support@futabarc.com

with replacing an antenna in the body of the email.

FCC doesn't care about modifying RXs, only TXs.

Default Thanks

Thanks for all the info. I'm just happy to know I have a rx that I can use. Could I just take the whip antenna off and solder on a piece of wire that is the same lenght as a standard antenna on an rx? That would be no big deal.
