Re: Serial cable question
Thanks for the reactions and possible solutions.
?
The USB is reacting good to Windows 11 commands, but the FT-847 is not recognised by several softwares like FL-Digi, HamRadio Deluxe or WSJT-X. I tested it with standard RS-232 cable and O-modem serial cable, but no luck so far. I have a USB model with an FTDI chip on the way to be delivered later today. Also had an older one that also works with Windows 10 and 11, but sadly no luck with it. Mind you Windows has no problems with it and I used a serial connection software check-up that sees no problems with it.
?
My radio is made in 1999, so I guess it is OK.

Hi,
Can someone advise me a USB to serial RS-232 cable that works with the FT-847. I have a model with a Prolific230GT chip that does not connect. I have done several tests with a serial check software, and it seems to work ok. No luck with the FT-847 connecting tough.

Re: Serial cable question
Wondering what you mean by it "not connecting" to the 847...?
Assuming you have an 847 with a recent-enough serial number to have
2-way communication, one thing that might be a problem is the
USB-Serial converter chip (Prolific, FTDI, and the counterfeit
versions) and the drivers on your computer.? I'd look for a
"Genuine" FTDI-based adapter, if you can find one, and if it really
is what it says it is.? I purchased one earlier this year, and while
it did work, the operating system very clearly identified it as NOT
an FTDI chip leaving me feeling cheated.? So, good luck in that
regard.
For troubleshooting serial problems I sometimes use an adapter that
has LEDs that indicate status of the various modem control lines and
data activity.? I've used this one, though not specifically with the
847:? ? No issues with the
chipset there.? Oh, but that brings up the other perennial
incompatibility, that between the straight-through and null-modem
(Tx / Rx swap) cables.? Serial interfacing is plagued with ports
wired backwards, wrong gender, etc.? I forget what I used with my
847. ? I think the rig is done the right way, but your cabling might
not be.? The LED indicators can help with that.? Check the rig's
manual on how the radio's serial port is wired.

Huge amount of noise on TP1002. But I was eventually able to sync on a signal that was nearly double the expected 45-ish MHz.. More like 76 MHz.?

I got the radio opened up this morning and finally located both TP1003 and the T1009 adjustment.
?
It looks as though someone has 'technified' this rig before I got to it. I found a single copper-coated spring steel 'finger' like one finds on radios that ensure the case is grounded to chassis ground. But just one.. and nowhere else in the radio were any like it and no place that looked like one or more had broken away.
?
I found there to be? 0.07 vdc on TP1003 regardless of state of RX or TX.. no change. This was with CW mode selected and RF power turned all the way down. I tried to bring pwr up to see what might happen with the voltage at TP1003.. While the radio still shows going into TX mode, no power is displayed on the S/PWR meter on the radio and none on the wattmeter I had between the radio and the dummy load.? And the voltage remained unchanged regardless of RF pwr control setting.? Then I discovered that the T1009 control was already maxed out (fully clockwise). I tried backing it off and the voltage at TP1003 decreased from 0.07 all the way down to 0.00.
?
I can hear the relay click on TX but still not even a flutter in voltage.?
?
I just get the feeling the problem is a lot deeper than a VCO adjustment. I'm still open to suggestions but I'm about ready to give him the bad news.? If he can find someone honest, that works on these things for a living, he might still be okay with it but it doesn't appear that I'm the guy for the job. I'm a hobby-level tech that works almost exclusively on old/vintage tube gear. If I HAD a pay grade, this would be above it?

7-26-2024 Update RE: [YaesuFT847] FT-847 only transmitting on FM mode. de: W1SMS
Andrew, Good morning – I am finally getting back to my FT-847 troubleshooting. ? Yesterday, I performed the test of TP1003 and adjustment of T1009. ? I found that there is a maximum voltage of 0.572 which varies by adjusting T1009. Note that this voltage is present in RX or in TX (CW) – it just remains steady. ? So, what is the next step ? ? Thanks and 73, Steve ? W1SMS Steven M. Simons ? ?

Hi there are a number of simple alignment steps, where the test point are peaked even with out much test equipment you can do around 80% ? Q1024 is a VCO locked to X1001 the component drifts over the years. ? I have known hams that when doing an alignment, accidently, move the wrong coil so make sure you find T1009 as it has many neighbours. There are manuals on this forum you can down load ? 73 ?

No. Nothing heard.
?
My HP generator does a good job of either AM or FM modulation and I had tested both functions on my Kenwood TS-590sg a few days ago.
?
But in this case I couldn't hear a signal at all and the S meter didn't move on RX.
?
I even tuned around a bit up and down in case the reference frequency had gone south but never found any signal.
?
One other test I did.. on 2m, I keyed up my Yaesu FT-50r on one of the local repeater frequencies and listened for anything on the 847. Again, tuning up and down almost 1 mhz each way.. Nadda.
?
I also took the unit off of the dummy load and connected it to my 6BTV in the back yard.. Setting the radio to FT8 frequencies (both 40m and 20m).. nothing heard other than standard white noise.
?
I fear that his radio may be not worth repairing.. but, not my radio and I'm not able nor willing to make a call like that.
