I noticed that my KX3 wasn't transmitting out of bands anymore... Not that I want to, or be a part of MARS, but in case of emergency, you never know... A while ago someone here emailed me a program to remove band limits. I had to run it on Window$, but it worked flawlessly. The 27MHz/11m band is still blocked, which is a shame. I can now transmit everywhere else in case of life-and-death emergency. Program is hereby attached. Use it at your own risk. By downloading it you are releasing me of any liability, would something go wrong and you brick your radio.

Are you sure that this software is for the KX3 ?

When I install it it, it states that this is for a K3 ?

Hello,

Yes, it is the same software for the K3 and the KX3. I would suggest that you backup your firmware before doing the mod. You can always download the latest from elecraft too. Make sure you know how to re-upload the firmware if something goes wrong.. I am not sure the version here is the latest, but worth a try.

When I had a KX3 (which I loved dearly...)  I had the 'MARS mod' using the software and it worked perfectly. The radio used to come out of the box 'open' except for the CB block, which is perfectly fine with me and keeps them out of potential hot water with the FCC. They began installing a han only block due to ham worry-warts who think that they cannot control their own radio and neither can anyone else.  Those 'numbers' nt he front of the radio mean something, so I read and obey - no biggie.  However, as Gil said, should there be a need (as opposed to a whim) to transmit outside of the ham bands, it is available if you use this software once.

Version 2.0.1 is the latest program from &lecraft.

The older version Gil provided did not detect my KX3 and would not modify the band limits.

Thanks John, what is your firmware version?

I now have a KX3 in my Florida Hurricane "Go Bag"  inventory along with two FT-817's that where easily modified for use in my EOC activities.It was a surprise that the KX3 with its fantastic antenna tuner  DSP qualites was locked from SHARES and other ECOM frequencies which are the Crux Radio Preparedness .
I find it funny that this "QRP radio it is still blocked on the CB sector when one can find almost every KenIcomYesu  100 watt mobile radios which can!
Many Thanks for the software.&3's

Has to be a legal issue. The other radios require a hardware modification, but the KX3 could be unlocked via firmware. Elecraft can't legally release the code... I guess someone would have to reverse-engineer the firmware and release the unlock code... Not sure if that would be legal, but as long as one doesn't transmit on the CB band, then the unlocked radio should be legal.

Hi Guys,
   Late to this thread, but need some help.
    I'm having trouble with both of these KX2/3 downloads, I can't make either of them open or run on my PC. I have a KX2, the programming cable, andKX2 utility on the PC and it all works fine.
What do I do with it all now?
  thanks for the help

Hi,

Did you get the latest versions from Elecraft?
The programs posted here are probably out of date...
