Re: CAT - Control - Yet another post
Is your 847 one of the early ones, without the bi-directional serial
capability?? That's why the UNI was created.? The symptoms suggest
yours is an early model.
There's a decoder table somewhere that lists what serial numbers are
in which group, but I don't have it handy.

unidirectional. I can get the UNI setting to work, sending

I am about at my wits end, and will probably use a different rig

Re: CAT - Control - Yet another post
I've been running JTDX with JTAlert and OMlog for so long that I can't recall whether Omnirig is used at all here, certainly not loaded as a seperate item.
Attached is a screen capture of my JTDX Radio config page. All I get out of it is PTT and the reporting back of frequency, the 847 has really limited CAT functions, no S meter or such.

Re: 60 Meter Transmit Mod Info Wanted
|
No TX on AM, SSB, on All Bands FM works fine
I wonder if any one can help me, my FT847 stopped transmitting on LSB, USB and AM, FM is fine with Full 100 Watts on HF and 50 Watts on VHF. I traced the audio going in and it gets to Q1043 at TP 1035, there in no audio I removed Q 1063, and the audio is back, Q1063 is is a voltage controlled attenuator, as it has an OP Amp on its input, this could result in a "virtual earth" on pin2 and the signal is getting dropped across the preamp transistor, however there is nothing coming out of Pin 4 which goes off to the Balanced Modulator eventually. There is a good 455 KHz if signal present at the Balanced modulator.
?
?The mic audio enters the radio via Transistor Q1043, then trough a cap into Q1063, on TP 1035 three was no audio! Rather odd. No Q1063 is an electronic controlled attenuator controlled by a voltage on pin 3, this voltage come from IC1093 pin 3. Now IC1093 is a strange device it received digital data from Q1105 the main Yaesu 100 pin microcontroller, as you turn the mic gain control up and down it sends a series of data to Q1053, and this turn send a voltage out to control the attenuator. To make matters more interesting the data is only a few bytes sent in less than a milli-second ?and only when you change the mic gain or select AM SSB, CW, of FM, the data is not continuous. My 2GB/S digital scope did capture the data, without it I would have been snuck!
?
I do not have a decent copy of the FT847 service manual, all the ones on line are photocopied and low resolution and when you blow them up they are unreadable, however, Roger came to my rescue, as he had a genuine FT874 service supplement.
?
Anyway this took 5 days to sus out, as I had no block diagram and no component over lay that I could read, so it took me up to 4 hours to trace each part and make measurement, some components were on the reverse side of the AF main board. To make matter worse, there are some undocumented mods on the back of the board close to the audio input attenuator, This digital transistor shorts out Pin 3 and 5 on IC1063, which increases the attenuator to Max, i.e. no AF signal leave pin 4 to the balanced modulator for SSB and FM.
?
However, there should be a healthy signal on Pin 4 and there is none, as the voltage goes up and down on Pin 3 in sympathy with the Mic gain control, the inhibit is not active. ( I have no idea when the inhibit kicks in) I have enclosed the data sheet for IC 1093, by no means a simple device.
?
Removing IC 1063 restores the audio to TP1035, :?
?
I have ordered a new attenuator chip, and will solder it when it arrives fingers crossed! ( I am not holding my breath on this one)
any pointers in the right direction?would be nice?

Re: 60 Meter Transmit Mod Info Wanted
Thank you for your reply. Do you have the specifics on how to make the mod? I've seen a couple of mods showing shorting solder pads, but there was inconsistency in which did what. I only want to open 60 meter transmit and not open any other transmit (i.e. 2M or 70 cm).
Thanks.

Re: FT847 FAN replacement ...
Hi Greg,?
there are two fans in the 847. The one on the rear panel runs continuously. The larger internal fan only becomes active in TX. Neither of them have any form of temperature control.
Most of the noise from the rear fan comes from the fact it blows air against a circuit board. If the fan is unscrewed from the radio, it becomes much quieter.?
One thing to note. The internal fan blows against the rear of front panel, and any dust tends to accumulate there. For the benefit of all owners, it is worth taking the cases off and? checking, and blowing any dust out. I have seen one with a 1/2" carpet of dust in front of the fan.?
?

Re: FT847 FAN replacement ...
As for my FT-847, I put a resistor in series with both fans to quiet them down. About 50 ohms if I remember right. Never had a problem and it's much quieter.
There was a discussion on the group about the fans quite some time ago. I saved the info - here are some of the notes: Perhaps you will find it useful.
A friend of mine found a slow speed fan that moves just about as much air but does it with much less noise. Specs are as follows:
Both fans size 40mm x 40mm.
Original fan: UC Fan; F412R-12MB-32; DC 12V; COPAL Co. LTD, Japan; Made in Malaysia; 5400 rpm; 0.06A; 1 ball bearing and one sleeve bearing; 0.15 cubic meter/min (5.3 cfm); noise 23 dB(A).
Replacement fan: Mini Kaze SY 124010L; 3500 rpm; 0.06A; sleeve bearings; 4.11 cfm; noise 14 dB(A). [Search for it on Amazon]
Installing the new fan involved only cutting off the plug supplied with the fan and splicing in the plug provided with the original fan.
I bought my fans from Amazon, but they seem pretty common for PC¡¯s, so they may be available in your area locally too.
The big one or front is 60x60x25 (mm) 12 VDC and the rear one is 40x40x10 (mm) 12 VDC. They were about $10 each.
Be sure to look for 6 bladed fans with precision ball bearings. Also anything listed as ¡°quiet¡± runs with a slower RPM and that is fine. I do lots of satellite work and have tested the rig running for days and my measurements with a digital thermometer indicated it maintained the ambient room temperature. For installation wiring, I pulled the sticker off the new and original fans and simply moved the radio¡¯s wiring cable to the new fans, then re-applied the round sticker back on the fan.
Here¡¯s some specs from one of the fans:
- Fan speed: Old: 5400 rpm; New: 3500 rpm
- Fan noise: Old: 23 dB; New: 14 dB
- Air flow rate: Old: 5.3 cfm; New: 4.11 cfm.

Re: FT847 FAN replacement ...
I have fans in my collection of spare parts.? This is of no use to you at all, because I am in UK, and you could be in Outer Mongolia for all I know. "Frank" does not give a clue to your location.? Take it out, clean it, and put it back in with a bit of thin foam over it.? The fans are generally noisy due to what the air is hitting, not the fan itself. If it is the fan, clean or replace. 40mm x 40mm.?

Re: CAT - Control - Yet another post
Hi Ravi, you are right about the serial number coding. Only, a number starting with a "4" is not older than one starting with an "8" as the production started in 1998 and "8" therefore was the first production year. So, the sequence is (199)8,(199)9,(200)0,(200)1,(200)2,(200)3,(200)4 and finally the year 2005.
Maybe it is easier to first get the serial data working with a simple RS232 link to a normal PC running WSJT-X or something. If that works, you can tackle the RigPi problem with more confidence.
Hi, Douglas, Bruno
I've used a Serial to USB cable to connect the rig to the Raspberry Pi
and the laptop. In both cases, the 'CAT' comes up on the rig, but
programs fail to complete the connection.
The Serial number that I made reference to was from a post:
"...Yaesu appears to use the following format for serial numbers on their
amateur products:
Year of manufacture-Month of manufacture-Production Run-Individual Unit
number, where the month of manufacture is offset by 2, so "C" means January,
"D" means February, "E" means March, and so forth.
Example: 8G051234 = 1998, May (fifth month, or "G"), Production Run 05, unit
#1234 in this run.
One key serial number range is 8G05. This seems to be the point at which
Yaesu had corrected the bi-directional CAT issue and made some other
improvements. This version was made in May 1998. Later serial numbers (e.g.,
8L09nnnn) all seem to have incorporated the earlier improvements plus new
ones...."
That would mean that the port was unidirectional prior to this, my
serial number is "4M950027", hence I was wondering what data is? that
the rig was sending back to the CommsTest program when tuning across a
band.
Thanks.

Re: CAT - Control - Yet another post
I know that this is an obvious question, but are you using a null
modem cable to connect from the PC to radio?
I've been using my Ft-847 for 2-3 years with a null modem cable
on HRD and have had no problems.
I let the computer boot up, turn on the radio, then open HRD. No
problem.
Good luck.
