MARS CAP MODIFICATION YAESU MOD

I know of several people that owned FT1D radios that were bricked by the firmware and had to go all the way back to Japan to be reflashed. Yaesu denied the fault for a week or two, until he persisted with them. One of their FT-991a updates really screwed up the original 60m band addition, and was found by another friend of mine. I am not a fan of the newer Yaesu radios (their FTM-400 had no front end rejection) and the warped process involved in updating firmware (multiple steps/power cable pulls, etc.). So if you end up with multiple 891s, make sure you either have all the same firmware versions, or keep the heads with the correct radios. It took me a moment to figure out what was going on when he called me about the anomaly, until I thought to ask if he swapped the control heads as well (which he hadnвЂ™t). The newer firmware added the 60 meter band in the вЂњBandвЂќ switch. This was because of the mismatch in firmware between my old вЂњmoddedвЂќ radio, and his newer control head (which he did not swap out at the time). All his bands were off by a factor of вЂњoneвЂќ, like he would select 20m, but get 40m, or 12m and get 10m, and there was no 6m selection. The results were goofy as my radio and control head had not been updated to the most recent firmware (as I noted, Yaesu firmware is very questionable), but his radio came with the most recent firmware. He had his unmodded radio in his vehicle with the separation kit, and swapped the radio bodies only (wanting to have 11m available in the mobile). I sold my modded 891 to my friend who had the unmodded 891 (that I did not want to experiment with). Those solder pads in the 891 are in a tight space. Should work.IF you can manipulate the screwdrivers while doing a reset on the radio (I seem to remember having to do a reset after the solder mod). I have mostly given up on amateur radio anyway, so my tolerance threshold has become pretty low when it comes to putting up with certain things in a mobile installation. I literally had the 857 set up so I never had to look at the radio while driving. I used to run an FT-857 in the mobile, and it was much easier to deal with in a mobile setting. In my opinion, the menu system is too cumbersome for mobile ops. While I think it is a good value for under $600, it is not an ideal mobile radio.

YaesuвЂ™s recent history with firmware updates makes me hesitant to do any mod that is not well documented. ItвЂ™s been a while since I saw the inside of his radio, so I donвЂ™t remember what exactly was different (may have been no shorted pads from the factory ?), but due to Yaesu changing something in there, I did not do the mod as I didnвЂ™t know what the outcome would be (especially when dealing with someone elseвЂ™s radio). I have a friend who bought an 891 in 2019 and when I went to do the mod, the arrangement of shorted pads from the factory was different from the photos online. I had bought my 891 within a year of the radio being released (and got hosed by Yaesu when they dropped the price, as they always do). Many thanks to Simeon Leriou, SV2GNM for his patience and his will.Just a headвЂ™s up on the 891 mod. Transmission on 40-224.995Mhz and 300-579.995MhzДЄfter the aforementioned modification you will have continues RX coverage from 504KHz up to 999MHz (including analogue cellular frequencies - NO GAPS!) Menu Item Misc Setup 17: Japanese (Instead of English) Menu Item Special Memory 6: JR (Instead of Marine) Menu Item Misc Setup 20: BEAT SQL (Instead of WX Alert) Bear in mind that resetting the transceiver by using the method for the USA version (holding down 4 + BAND + V/M and powering up the transceiver) WONвЂ™T work! It will just enter a curious set up: This will display the Vertex Standard logo instead of Yaesu. Reset the transceiver by holding down MON/F + HM/RV + Internet Key and power up the transceiver. Reception was NOT possible anywhere outside these limits! Prior to any modifications the transceiverвЂ™s jumpers was soldered on positions 2,4,5,7 (factory setting) and the unit was capable of working on the following frequencies ONLY! I own the B1 European/Export version (Label outside the box indicates DST:EXP / TYP:B1). EUROPEAN/EXPORT (B1 VERSION) This is to inform you about the European version VX-7R modification.
