FT847 Power buttons

 

Hi,
? ? In the past I have been repairing FT847's and now I have a surplus of replacement power buttons.These are genuine Alps Alpine from the USA and identical to those used by Yaesu (I've seen them side?by?side and they are identical).

? ?6 posted to the UK, International buyers..... simply too expensive unless you want 10 or so.

Hi Spence, restrict it to Yeasu only if possible, test equipment ok.

Go for it. As long as you aren't spamming all the time I think it might be OK.

Re: FT 7200 yx band

 

The USA frequency settings may extend the 40m band, if not just live with the full extension and you will also get 60M

Hi All.
I bought some years ago FT847.
Rig is ok and good condition.
Some years ago at OH we got extension to 7 MHZ.
Here is allowed now up to 7200 kHz, and rsdio
can transmit up to 7100 kHz.
I have running around web and only mod
I found to make it transmit full HF? bands.
I dont want to that, just missing 100 kHz.
Any Ideas ??

Re: FT-847 power switch

 


For what it's worth...
I did what is shown in the video years ago, paralleling the contacts and adding a 0.01 uf cap. It's pretty easy as the front panel tips down. Never had a problem. And I do turn the radio on and off with the PS just to be cautious. Also, I bought some spare switches. I don't remember the source but it was either Digikey or Mouser. If you would like the P/N I can look for the spare package. But that could take a month as I am on travel. There should be a note in the files somewhere.

Re: FT-847 power switch

 

I would suggest you do not just turn psu on, it will more than likely have a voltage surge on switch on.
Disconnect positive from psu, turn on psu and then connect positive.
I have plenty of switches in stock, that are on ebay, but ebay vastly inflates the price for shipping to abroad from UK.?
Direct is considerably cheaper.

HI

Years ago I had the same problem too.

Sooner or later it happens to everyone, it depends on how you use the radio to know if "BEFORE" OR "AFTER"...

?

The first time I shorted the contacts with the other position, then that one also blew and I replaced the switch completely with a new one which I found identical.

?

It has held since then, but it will happen again...maybe...

I always use the radio, now these days I notice another problem that gives me little VHF power... maybe the power amps or something else...

I've been using it for years and years now... something had to happen... unfortunately.

Re: FT-847 power switch

 

Mine was modified years ago when replacing the switch. Paralleled the contacts so both sets of contacts are used instead of just on side of the double pole switch.

As you have to strip down the whole front panel, I would leave it in the on position if that is possible, I would only strip down, if I could find a replica part.

From what I have heard this is a common problem.

I have heard that shorting the switch contacts to the unused pair on the pcb will get around the issue. But proceed at your own risk. I am sure that a search on the switch problem will show many people advising the same and some with pictures showing how to do it. But as I say, I have not needed to do this and if you do so then you do it at your own risk

The power switch on my FT-847 is starting to have issues and while I am in the process of locating where to have it replaced, is it advisable to use the power supply to turn the rig on and off?
Thanks in advance

Hi Hal, this is a circuit I use for all sorts of data modes, this one I made for my Clansman kit.
The circuit is always the same just the wiring details change, it's cheap and easy to make.
