Re: Ft-817 PA board
开云体育This is the first I've heard of replacement FT-817 PA boards being unavailable.Such a rumor, even if not true, runs the very real risk of starting a 'run' on these boards by FT-817/818 owners... I wonder if it would also be wise for an FT-817/818 owner to secure a replacement display module as well, as long as they are still available? Please report back your findings Mike, Ken, N2VIP On Aug 4, 2024, at 18:04, Mike Bryce <prosolar@...> wrote:

Ft-817 PA board
Gang,
?
from what Ive been reading, it doesn't sound good for the home team. I plan on calling yaesu tomorrow afternoon and find out the status of the PA replacement board.
?
So, two questions;
?
Has anyone actually replaced the active MOSFETs on the PA board? I watched Peter from TRX Bench do it, and it look daunting.
?
And two, incase there are no replacement boards from the factory, any one have a spare PA board they are will to sell?

Eric,
Thanks for the information. I have the original box so the serial number is right there it is 1G35xxxx. April 2001 batch 35? ?Correct?

Re: Blown final club? I think I have a membership
This happened to mine. It also took out the two relays that select the front and rear antenna jacks. I ordered a FINAL UNIT in 2021 and installed it. They didn't have the relays and had to wait 8 months for them. I wanted to order a spare FINAL UNIT, last month and Yaesu USA has NONE. They did not seem interested in getting any more in stock.

Re: eBay filters
Hi,
?
the choice of the bandwith has a lot to do with personal preferene.
The cfj455k14 are often in reality around 2.2k kHz wide at -6dB. This can be desired in crowded band conitions.
?
I prefer a SSB bandwith of 2.7 kHz and have in the past replaced this filter with the cfj455k13 on serveral rigs and not used the optinal filter slot. I find the audio much more pleasing.
?
It is important to adjust the carrier offset in the service menu to get the optimum slice of the audio spectrum as the filters are variing in their center frequency.
?
The downside of a wider filter is a bit more "monkey chatter" in a crowded band.
?
Besides that, this filter defines the audio banwith of the tranmitted signal.
?
You may want the better audio fidelity, or prfefer to concentrate your rf power on a smaller bandwidth to be more "punchier".
?
Your rig, your choice.
?
73, Chris

Dean N2TNN wrote…
I have an original FT817 and need a backup plan.Apparently the supply voltage is connected to the finals all the time. My understanding is that if you leave the internal battery in there, when it eventually runs down, the final goes into oscillation and destroys itself. If you haven’t lost your final yet, just keep doing what you’re doing - hi! With that said, if you could round up a spare or two, it would not be a bad thing. When it happened to my brothers radio, he ordered two replacements. He still has the second spare sitting there. -- 73 Keith VE7GDH |

Can you explain in detail how the get the new boards. Google does not reveal any lead to obtaining a new PA board.

Hi Mike, sorry to hear about the potential final loss but replacement boards are very inexpensive,(I bought 2 for $60+ total a year or so ago from yaesu USA. Regardless I would buy a couple of spares for your 817s. The boards fit all 817-817nd -818nd families. By 73 Rick VE1RNM On Sat., Aug. 3, 2024, 6:41 p.m. mike bryce via

HighSWR into a dummy load on rear port…A few years ago, I acquired a used FT-817. I seem to recall that one screw was missing from the SO-239 connector. I suspect that some force had been applied to the connector and the soldered connection for the centre pin had broken off from the circuit board. I replaced the missing screw and re-soldering the center pin was an easy fix. -- 73 Keith VE7GDH |

Blown final club? I think I have a membership
Okay everyone, I think I may have joined the blown final club.
I was listening to the maritime mobile net on 14.300 and thought, what the hell? See if 2W might get the net control’s attention. The 817 reported ‘highswr’ on the rear antenna port, so I went to the front and the highswr went away. However in both cases, the power meter only had on bar lite even though power for set for four bars. Highswr into a dummy load on rear port. That’s not right! So, even though the power jack is fubar, I can squirt in DC and at 13V input, I still get from 1 to 0 bars and the radio is only drawing 530ish mA. That sure sounds like a pop PA board. Makes no difference if I’m on HF or VHF, no bars or 1 flickers a bit. I can hear myself on another radio i.e. 146.52 rx and while tx on the 817. This is an older 817, I don’t know the vintage, so this being the weekend, does any one know the approximate cost of a new PA board from Yaesu? Can you still get ‘em? Is the PA even bad? Mike wb8vge FYI…. I put my other 817 on line and the net control gave me a s9 report. I am in ohio, he was on the west coast. That Yaesu 817 is an amazing little rig! |

The 2024 Flight of the Bumblebees is now History
The 2024 Flight of the Bumblebees is now History. ? There were 207 Bumblebee Numbers assigned this year.?? Wow!? ??Phil - K4PQC, and I were really pleased from seeing the interest shown in getting out and operating portable in this long standing QRP CW event.?? And we could not have done it without Bruce - WA7BNM generously providing the FOBB auto-logger. ? ? The band conditions made operating QRP CW from portable locations a real challenge everywhere.?? But I guess if we choose to work QRP CW, we like challenges.? Right? ? The weather was a mixed bag, with severe storms in some areas of the country and very high temperatures in other areas. I got well cooked where I was at. ?Some Bumblebees had to revert to becoming home stations due to the weather.? Others had to cut their operations short. At least one Bumblebee confessed to getting quite wet.?? But, assuming that everyone returned home safely, then all is well. ? Be sure and enter your Results and Comments.? Even if you were only able to make a few FOBB Contacts. ? It has been pointed out that pictures of Bumblebee operations have been part of the Flight of the Bumblebees ?tradition.?? I know that I always snap a few pictures of all of my portable operations - maybe most of you routinely do that also.? But we lost the ability to send in pictures of our operations whenever we switched to using 3830Scores.com. ?? ? So, we will setup another web page to display the pictures that Bumblebees and Home Stations wish to submit.? It will probably be called '2024 FOBB History', and it will be available on ? ? Send your FOBB photos to:? fobb-pictures@...??? Be sure to include your call sign, name, and location so I can tag your photos properly.?? . ? ?I will post them to the web site as time permits.??? Sorry, no prizes or awards for best picture or best location. ? And, while you are waiting for the 2025 Flight of the Bumblebees on July 27, 2025, you can try your hand at the Monthly ARS Spartan Sprint on the First Monday of Each Month.?? That Monthly QRP CW event was also originally intended to promote outdoor operations.? But the evening hours make that difficult to do East of the Mississippi.? So, it has pretty much evolved into everyone operating from indoors. See for Spartan Sprint information and rules. ?? ? 72, Jody – K3JZD ?and ?Phil - K4PQC Adventure Radio Society Trustees |
