Does anyone know if you can get hamband on JR 10x. I had heard that you can't.

The 662, 378, 8103, and 10X as well as all receivers 6 channel and up
are available on 50 mHz.

Ok, I followed the link, but I didn't see the specifics on the 50 MHZ. However, if you say they do, ok. Where do I go on the net to get qualified for this, and once I get qualified (Ham License) do they have to send me a new module?, or do I just send my module in they convert it?

A few things:

1) Ham isn't CB. You MUST pass a test on behalf of the FCC to get the license, and you MUST take the test in person. The Technician class is the minimum for 50MHz R/C, and that will require you to pass basic rules and theory, but no longer any morse code.

2) On the 10X, the module is available on 50MHz, and it is a different module than for 72MHz. The replacement will run you about $50.00. You do not need the license to buy the module, but you CANNOT legally use it without the license.

3) Same goes for receivers. You will need to buy an RX on 50MHz - no conversions or crystal changes will take a 72MHz to 50MHz. Good news, is JR prices are the same no matter what freq. you want.

question, I found this:

My 8U operates on channel 56 (72.910 MHz) but a change of crystals can shift it to any of the R/C channels 11 to 60 if the need arises. Also, as a modular radio, I can even shift it onto the 6-Meter HAM band (channels 01 to 10)!

If he's on channel 01 through 10, isn't that HAM on 72 mhz?

Also I found this:

50.000-50.100 CW and beacons
50.060-50.080 Automatically controlled beacons
50.100-50.600 SSB
50.125 SSB DX calling frequency
50.200 SSB domestic calling frequency (Note: Suggest QSY up for local down for long-distance QSOs)
50.600-51.000 Experimental and special modes
50.700 RTTY calling frequency
50.800-50.980 Radio Control (R/C) channels, 10 channels spaced 20 kHz apart (new)
51.000-51.100 Pacific DX window
51.000-52.000 Newly authorized FM repeater allocation
51.100-52.000 FM simplex
52.000-52.050 Pacific DX window
52.000-53.000 FM repeater and simplex
53.000-54.000 Present radio control (R/C) channels, 10 channels spaced 100 kHz apart

My question is the JR stuff on 53 to 54, or 50.8 to 50.98?

tadawson

Frequencies 0 - 9 are HAM, on 50MHz. I think JR also has/had 53MHz available, but I think I recall hearing Danny say that they were pulling away from the 53MHz stuff, but will still provide gear on the "channelized" 50MHz freqs. As far as I know, there is no HAM frequency allocation in the 72MHz band, and even if there is, it is definitely NOT channels 0-9!

From the AMA member handbook:

2.1.4. 50 MHz Band - Identified as CHANNEL number frequencies:

50.80 CHANNEL 00
50.82 CHANNEL 01
50.84 CHANNEL 02
50.86 CHANNEL 03
50.88 CHANNEL 04
50.90 CHANNEL 05
50.92 CHANNEL 06
50.94 CHANNEL 07
50.96 CHANNEL 08
50.98 CHANNEL 09

Most JR equipment is available on these 50 mhz frequencies.
50.800, 50.820, 50.840, 50.860, 50.880, 50.900, 50.920, 50.940, 50.960, 50.980
There is a select number of items, like the 610 receiver and the airpacs, that are not available on 50 Mhz.

We no longer sell new equipment on 53 Mhz due to problems with these channels in many parts of the country.

Danny, what do you make of this comment below?

I just talked to them (hobby services) myself and as long as you buy a crystal set that the
dots are within one place of each other you are fine [to switch crystals on your own in your module to a different channel]. They do recommend
having your moduels tuned every year if you fly a lot.

dsnyder

For the receiver, you can freely change the frequency in the band that it is on. For the transmitter though, it is against FCC regulations to change the frequency except when performed by an authorized service center. It is a good idea to have your equipment checked out on a yearly basis if you fly a lot, and if it is less frequently, perhaps every other year or so.
