  1. Hi Simon. Thanks for the Info on the Yaesu FT-65/E Radio Tx unlock. It works like a charm!
    Do you have any information in relation to the difrences between the Aisan and European versions? as far as i can see the units and frequencies are the same, the only obvious diffrence being the lack of the Scrambler function Menu Item 39 on the European version.
    I guess what im asking is there any way to put the European verson into Asian Mode to activate the scrambler (voice inverson) function. either by a code input or jumper soldering? or is there a phyical difrence in the units or the firmwares?
    Any information would be apreciated!


  2. buenas tardes,
    pertenezco a un grupo de rescate en Colombia y tengo un yaesu FT 25/E comprado en E.U, realice todos lo pasos que tu mencionas para desbloquear o extender la banda del equipo, el radio se reinicio pero no se desbloquea. agradezco que me puedas ayudar con este tema.

  4. Hi Simon!

    A question about moding Midland GB1 to “export mode” – is there any soldering needed or is it purely software related issue?
    PS! Thank you for running such an informative blog! Respect!



  5. Hello.. My friend has bought CRT 279UV. In VFO is able to set any freq., but when opened in any SW to program memories, there is band limitations 144-145 and 430-439. Unable program standard HAM repeaters, nothing outside this range.
    Anny suggestion how to expand this?


    • Unfortunately I haven’t got it in my hands, but my friend bought it via local reseller and haven’t doing any modifications. But in VFO mode normaly operating in HAM bands. Yesterday we have been trying program memories, him first and me then via remote desktop and found this non-standard range. If it was out of the box, there should be at least 144-146 but not 144-145.
      70cm we have also 430-440 not 430-439, most of the repeaters have downlink above 439. We have tried it with CHIRP and CRT-VIP-CTS – same issue found. Today evening will try your unlock procedue and will see, if have changed. I’ve go Bao GT3TP and there was possible change it Chirp easily, in this case the range is greyed and unable to change.

      I have not much experience with those chinese radios, not understand, why memory and vfo range are different.


    • Understand you very well. I did check and the radio comes standard 144-146 and 430-440 MHz they told me. So it could be ok as 440Mhz. If not ok let me know and I’ll ask again, but code should work. Others used it and told me it’s ok. It does seems rather strange if you’ve got 144-145 and 430-439


    • Well, unlocking helped, all freq. programmed succesfully..
      Just in Chirp was not able set channel+names on display, was set via CRT-VIP
      All as QYT KT-9800D model..

      Thanks for help.. Best regards..


    • I was asked this just this morning. AT-5289 needs programming software to unlock it fully 25.6-30.1 and can use same programming cable as the Stryker SR-955 / SR-655 / CRE8900 and Alinco DR-135DX


  6. Hi Simon, i don’t suppose the Yaesu FT-891 TX MARS / CAP Mod is available yet is it, i’ve approached Yaesu UK but they refuse to issue me the info

    Kind Regards,
