TX ERR on 40m from .101 to .200

Andy M0DEL All Messages By This Member #110033 One of my FT817nds (serial no 4H) won’t transmit on the top half of 40m. My other one is fine and this one works on the lower half and on all other frequencies. I’ve just started using this one on 40, previously it’s been 20m and above. Anyone any ideas please? A web search has only brought up “won’t transmit at all”. Any help gratefully received... Cheers, Andy M0DEL
Mike Olbrisch #110034 开云体育 It is probably set to the earlier European 40m model, 7.000 to 7.1000. ?

tomsdad97 All Messages By This Member #110035 开云体育 Hi Andy – a memory lurking in the back of my mind, didn’t the UK have a reduced 40m allocation at one time? ? Perhaps this 817 dates from that time and has the reduced band set internally? ? Just a maybe, good luck! ?

Mike Mynn #110036 开云体育 ?Hi Andy, I had the same issue with my 817. You need to open up the band by either soldering some pads in the head (display) assembly or by using software. Soldering the pads is rather tricky due to the size and space inside so you need to be confident soldering. If I remember correctly you remove Some pads and add others. The software route is the easiest but is not permanent. Both options will give you 7.0 to 7.2MHz TX. Google “M6PWLradio” and look under Useful Information, I have a copy of Yaesu’s official method to open up the frequencies. Unfortunately I can’t remember where I got the software from but I found it with Google. Best regards Mike Mynn (M0PWL) De Mike - M0PWL Isles of Scilly, IN69UV, EU-011

David Lisney All Messages By This Member #110038 开云体育 FWIW my elderly FT817 needed “expanding” to cover the extended portion of the 40m band, I did mine via the “jumpers” sadly a side effect is losing the ARS functionality. 73 de G0FVT ? Sent from for Windows 10 ?
Mike Olbrisch #110039 开云体育 That is interesting…….. I had always thought-heard-been told only the FT-817 could be opened up with software.? One of the “improvements” of the FT-817ND was that it took a physical MOD to open up the frequencies.? And he clearly stated he has an FT-817ND. ?

Andy M0DEL All Messages By This Member #110040 Thanks for all your suggestions. I did wonder about the old uk allocation but thought it was expanded before the nd was released. I’ll let you know when I’ve got it sorted. Probably not immediately due to other commitments ? 73 Andy M0DEL?

The application i used was called 'softjump', this appears to just change a 2 byte value in the rig and it stores the previous value to revert the mod. I was real suprised i still had the app & the file to revert given now long ago i extended my 817 ! It may still be available for download (google search suggested), if not let me know and i'll share it with you. 73 ? -- Peter..... (G1FXE)
Andy M0DEL All Messages By This Member #110043 Thanks to all who responded. I tried the Widebander software mod (Thanks Robin G4JDO) but to no avail. Plucked up the courage & downloaded the Yaesu jumper mod sheet and reset the jumpers and all’s working great. I kept a record of my settings and restored them and the little rig is as good as new (and transmits everywhere I want it to ?. Hardest part of the mod was reseating the ribbon cable! 73 de Andy M0DEL

Mike Olbrisch #110049 开云体育 That is interesting Peter. The solder-blob change to the ND version panel unit was a requirement to pass type-acceptance.? Before that, using the software to modify it made it too easy to use the radio in places it was not designed or accepted for.?? I do not believe CB was the issue in this case.? While VFO control of the transmitter is still illegal on CB, I can’t see any free-banding CBer going through the trouble of using an FT-817 on a measly 5-watts when so many other 100W+ radios were available.? OTOH, why do we use the FT-817-series on a measly 5-watts?? Portability!? The FT-817 provides a level of portability that no other SSB-CB radio can match. Side-note:? I once owned a Belcom LS-202.? That was a 2m-HT.? It worked FM, and SSB!? Someone talked me out of it, and to this day I regret selling it.? And I’ve never seen another. There were 4 major changes to the FT-817ND.? The software programming was changed to the solder-blob configuration.? The violet back-lighting was added.? The 60m-band was added.? And the final board was improved.? I believe your radio is likely a very rare exception.? If you know, what version did you get?? If you modified it some time ago, you may not remember.? I also wonder if you ever replaced the final board, and if so, was the original the non-ND final? Long ago I had copies of the Yaesu technical bulletins spelling out the serial number effectivity of the changes.? The change from 817 to 817ND was in lot-30.? I no longer remember how many radios were built in each lot, I only recall is wasn’t an even number that one would expect.? I wonder if you ever tried to decode your serial number totally? One of the minor difficulties with the USA version of the 817ND was that the USA 60m channels was changed, and CW/digital was also added.? Yaesu made no attempt to correct this in radios already sold.?? However, the free program CHIRP will allow you to edit the 60m frequencies and modes, and I have done so here, adding CW for the two lower channels.? I have considered modifying mine for full 60m coverage for when I visit Europe, but I really cannot recall if I ever made a 60m contact there at all.? I can check that quickly…… NO.? Of the hundreds of contacts I’ve made throughout Europe, not a single 60m contact.? I need to fix that, next visit. I was talking last night on the local 2m-SSB net.? I was sitting out in the garden using the FT-817ND.? I think there was only one or two stations on the net I could not copy.? Several stations were surprised at how well 5-watts on a rubber duck antenna was doing.? The farthest station I worked was 26 miles away, and the other side of a 7,000+ foot tall mountain.? He mentioned that he had owned an FT-817 several years ago, but sold it.? And hearing me sitting in the garden, he wished he had kept it now.? I told him that in my opinion, 80% ± that sold an FT-817 had bought another within 2 years.? He said it was just about 2 years ago when he sold it, and maybe it was time for another.? We were both laughing about it. ? Mike – KD5KC -- El Paso -- Texas. ? The canyons are calling, colorful and deep.? But I have promises to keep. And miles to go still in my Jeep...??

Marty Hartwell All Messages By This Member #110051 开云体育 Hi Mike and Peter I have been following along here with this discussion, and just noticed that Peter is and I would presume have a UK version of the ND. While Mike has a US version of the ND. Might that be a possible cause of differences between what is seen and allowed to be used to modify the rigs? Just a possible cause of the difference. Good discussion though, I did buy my first 817 in 2003 if I remember right at my age it is possible I am off a year or two. I sold it in the middle of the time Ten Tec came out with the 516 Argonaut so I sold it and got one. During use I found that the 516 was not happy with battery power when it dipped below about 11 Volts which didn't take to long. Requiring the use of a AC PS and hampered my portable activities. So sold the 516 and purchased another 817 in about 2006 which was again an original model. Had it every since and is my only working ham rig. Love it, and I do have a 40W HFPacker amp model IV that I can boost the power out on the HF bands but don't use it very much. On digital modes I find that 2 1/2 watts or 5 watts is usually enough. Cheers guys.

Marty, You are correct I do indeed have the UK version but it does appear that my rig is somewhat unique in allowing a Softmod as others with UK versions (including my colleague who bought his within weeks of my purchase) are unable to use this method BTW I also have a HFpacker amp..well most of it anyway as I have still to complete the build ! ? -- Peter.....
