TX ERR on 40m from .101 to .200


 

What is the cable’s pinout to use for the M0BMN widebander software ?
?
Thx,
73 Ben?


 

After some considerable searching I couldn't find any reference, but Geert's comments on
?
?
are helpful. Resetting the radio post mod. seems to be a general requirement. Personally I ignore ARS due to the different in band offsets and directions that are required over here on UHF.
?
Back to the thread then- apologies.

I recall reading somewhere that loss of the automatic repeater shift is dependent upon whether or not that facility is enabled prior to carrying out the mod. I'm sorry that I can't remember which state it needs to be in before going ahead nor any citation. It could well be in Clint's excellent website? A web search then ...

No. Nice try, though.


 

This mod should get you aligned with the US band plan?

Good luck,

Hi have a look in the service manual,? you can change the links on the back of the display for band plans

Try a search for "M0BMN widebander". That was the software I used to use to unlock coverage for 60 meter operation.


 

Hi all, sorry to undig this topic but I'm testing a FT-817 for a friend and saw that exact problem : TX ERR above 7.100 kHz. Could someone gives me a start point, as the previous pdf link is not available anymore ?
Thx, 73 Ben - ON5BGO


 



Try this link - hope it helps...

Hi, could you provide the link to the Yaesu jumper mod sheet you described please??

That group are designing yet another amp, much smaller is footprint too and more

upgrades since improvement in design features. From my experience and lack of

much use for the current one I am not sure I would sell mine just to build a newer one.

I think if anything I would keep what I have and I need more power or features I would

go with an FT-991 maybe.

Not doing much of anything for the time being though.

PS. By the way during one of my longer trips to UK in the 80's I had the good fortune

to meet the Rev George and attempt to operate from a park in Oswestry with a very

under powered TX and very poor antenna with a home brew small unit. With a nice

antenna from the home area on a better antenna it worked fine.

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 !

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.

Mike,
As previously I certainly have the 3 colour back light & the 60 metre band. I'll have a look later i the week to see if the solder blob points are there & what PA is fitted.
Funnily enough much like your contact I regretted selling my original 817 hence picking up the ND version quickly afterwards.

I found it odd at the time that I managed a 'software mod' when my colleagues ND had to be de-blobbed or blobbed (can't remember which) ;-)

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 anything is possible. I haven't disassembled the radio? to have a look. However, I can confirm that the display has the 3 back light selectable.
