I have a amateur radio model No FT11R and would like to know how to recieve the airbands on it. malcolm G6PIB?

Question

I know this handheld can be used on other than the ham 2mtr band, unfortunately I have misplaced the user guide so I am completely lost now. This is due to moving house from Bahrain to the UK. Can someone with this model radio help. Malcolm ex A92EV now G6PIB.

Answer 1

Hi Malcolm,

This answer is taken directly from mods.dk. It opens up the receive and transmit. I take no responsilibilty for this modification, and you need to check the liabilty.

I have knowlege that this mod works, but take no responsibility for any damage it does to your radio, the legality of this mod, or any other incurred damages.

After the mod a FT-11R will have:

Recieve: 110.000-135.995 (AM) 136.000-180.000 (FM)
Transmit: 136.000-180.000 (FM)
Empty Memories and a completely reset radio

First, Remove the antenna, battery pack, and pocket clip (if installed) from the radio. Then remove the four black screws from the corners of the main section of the radio, the two black screws from the bottom center section of the main body, and the two silver screws from the bottom of the keyboard section. Now carefully separate the back and front halves of the radio, taking care not to put too much strain on the internal ribbon cable, or loose the small metal strap holder or the battery release button.
Once you have opened the radio, carefully remove the metal plate covering the back of the keyboard. Then remove the "AF" pcboard by first removing the two copper screws in the middle of the board, then holding the bottom of the pcboard and the mic/speaker jacks between your thumb and forefinger and pulling straight up. This may take a little force, as you are seperating two connectors. Once you have the "AF" board removed, set it and the connector/keyboard backplane board aside. Now look at the lower left corner of the controller board. You should see the 8 jumpers (they are very small), set up like this:


Top of radio

L A o-o o o E I don't know how the jumpers relate to the
E B o-o o o F ones on the schematic, so the letters are just
F C o o o/o G for reference in this article
T D o-o o o H
"-" means a solder jumper, and "/" means resistor

These are the functions of the jumpers that I know of:

A- Turns your radio into the euro version (TX between 144.000-146.000)
B- ?
C- ?
D- This is the important one. Gives you extened TX range
E- Turns your radio into the 440Mhz version. Not Suggested!
F- ?
G- ?
H- Same as jumper "E"

The only jumper that this mod deals with is "D". It currently has a solder jumper across it. Remove the solder across the jumper with really small solder wick or a desoldering station, taking care not to touch any plastic with your soldering iron. Once this solder jumper is removed, you now have extened tx range. Now carefully replace the "AF" board first, and then the connector/keyboard backplane board. Take care to get the copper grounding connector on the side of the mic/speaker jacks well seated. Replace the two copper screws in the middle of the "AF" board, and the two silver screws on the bottom of the keyboard. Replace the battery eject button and strap holder, and then replace the back half of the radio. Replace all the screws, put the battery and antenna back on, and turn the radio on. You should see 144.000 on the screen. Turn the radio off and the hold the MHZ/ and MHZ/ buttons while turning the radio on. You now have the transmit range between 136.000-180.000.

As a suggestion, you can store completely different transmit and recieve frequencies in a memory (see manual), so if you store a service frequency in a memory, you can program a legal HAM frequency as the transmit freq. so you never accidently transmit on an illegal frequency.

Another neat feature that I have found on these radios is the "Clone" feature. You can transfer all memories from one FT-11R to another FT-11R. First, make a cable using two male stereo 1/8" connectors, and connecting the top(gound) and middle conductors of the plugs straight through. Don't connect the tip conductors together though. Plug this cable into the earphone jacks of the two radios, and on each radio, hold down the "FM" button while turining it on. You should see every character flashing on the screen. Now, on the radio which you wish to recieve the memory contents from the other radio, press the MHZ/ button. You should see "RX CLN" on the screen. Then on the radio which is to send it's memory contents, press the MHZ/ button. "TX CLN" should appear on the screen for about 5 seconds, then it should return to the flashing screen state. The recieving radio should now be in normal operating mode. Turn both radios off, and remove the cable. That's it. This function overwrites all of the recieving radio's mem contents, and copies everything from memories to pager codes to the status of the light. WARNING: The instant that you hit the MHZ/, your memories are GONE, even if the transfer is unsuccessful! Also, both radios must have the same jumper settings to successfully complete the cloning process.

That's all I know for now! Have fun!
