A note about Files Ownership: Whoever uploads folders or files becomes the owner of those items even though he/she may have never actually had anything to do with their creation and original posting. For the Original owner to regain control over the items here is my suggestion - 1 - Create a new folder with the same name but add an asterisk (*) at the end of the folder or files name. For example an existing 6146 folder would have a 6146* folder next to it (if sorting is by Name). 2 - Copy the 6146 folder files back onto your computer. 3 - Load the 6146* folder with the files. Change the comments section as required. 4 - Ask the existing folder owner, group owner or a moderator to delete the original 6146 folder. 5 - After the 6146 folder has been deleted you can delete the * at the end of the name.

Gyus, I am seeking your advice on the WIDTH/SHIFT pot... perhaps a well known problem but I am new to these radios. I am in custody of two FT-980s that a local Ham donated to me recently. Both had the SHIFT shaft cracked (the part past the Y split). I reinforced one shaft, electrically restored the radio and finally put in on the air, only to realize that the SHIFT broke off completely. Sad story, and this otherwise fine radio is now defaced. I would like to restore it. Having a replacement part would be ideal but it could be my Christmas wish, right? HI. So I am thinking about a repair. Is there a way to disassemble the pot and replace the shaft only? The shaft looks like a relatively common JA part from the 80-ties and perhaps could be had from other radios. 73, Wald N4PL Rigs here: FT-980 Tempo 2020 Uniden 2020 FT-101E Drake C-line Elecraft K3

Hi, I've been trying to access the old Yahoo group files but there seems to be some problem. Can anyone assist? Thanks Mark VK2MOH

Hi, friends, I have noted in my FT980, in GEN mode, at any frenquency when I active TX in USB the current in the final state (METER I), rise uo to 10 A, even without audio in microphone and DRIVE and MONI en minimun. In LSB the current is zero, normal. Any hint to this anomaly? Tnx.... CP6CL - JOSE Dr. José Carlos León Ortega UDI- Universidad para el Desarrollo y la Innovación Tel.

Reading through the various literature and commentary from yesteryear about the FT-980, it's mentioned that an Auxiliary band ROM was never offered for the rig - nor was any programming data provided...at least in the English version of the Technical Supplement. The ROM is a bipolar type and a 74188/74288 appears to be a suitable replacement. There are others. A gent by the name of Callan Brown offers something termed a "FLEP" - a daughterboard which allows the use of a QFP type EEPROM in place of a bipolar ROM. It was originally designed for the video game market. I bought a couple last year and when I source a couple of Harwin headers I'm going to have a go at developing a programming map for the ROM. 60M coverage will be high on the priority list...and since there are only FF combinations of data to try it shouldn't be that difficult to map all the HF ranges. Even if I have to try every value. Before I start this effort: Is there anyone in the group with a '980 which actually had an Aux band ROM installed....either by Yaesu or by a 3rd party? I have four of the rigs at present plus a spare CPU Unit and none have the ROM present. Nor have a number of other 980s which I've examined. Alternatively, do we have access to the Japanese-language Technical Supplement (which may contain the ROM programming data)? 73 - Fred, N8YX

Hello gang. I am getting a ALS-1306 amp and need to make sure how to hook it to the amp. I have a FRB-1 relay box and assume I just need hook the amp into the input the the actual relay box. I need the box to connect to the ACC-2 on the rear of the 980. Ameritron lists a connector for the FT-980 in their list of cables and this can go from the amp to the input of the relay box. I also have the Ameritron 704 relay buffer. Not sure I need two buffer relays. The FT-980 stays in amp position 1 or non QSK. Any suggestions or corrections. 73 Dave K4JRB _._,_._,_

Wald, Hope you get the 980 CAT working. Remember the FT-980 was about the first and the first interface was a FIF-232nfor apple. The original FIF-232 for windows worked on w3.1 then w95. The IC-7300 and dual receiver version IC-760 have the interface built in so you can do digital directly on the PC. THe Galaxy needs work so I will test tubes and resistance. Two of the switches are hard to turn. I tried to get my later MFJ DVK to work on the aligned FT-980 with no luck. Looks like the battery needs replacing. Got out the basic manual for the IC-7300 but ran out of time. I did find a Yaesu Desk mic in the box from the donor and it modulates the SSB so this tells me ssb works so I will look into the dvk. Made a few QSOS including a TA3 and 5T5PA on 20 but did not find anything on 17. May order a 3-500ZG from the Henry Radio Ebay store. I need a clue to find the cables with clips so I can test parts better.

Hello Gang, Does anybody have a spare and not needed XF-8.9HC filter for our radios? I checked QRZ/QTH swap and the eBay... nothing. I am upgrading my second FT-980 with the intent to put it into more regular service. It has been fixed up and is working fine, just needs the CW upgrades. I was fortunate to find the XF-455MC source for the 2nd IF. Please contact me off the list with the price + shipping. Mni thx for reading, 73 de Wald N4PL

Fellow enthusiasts, My FT-980 has a curious ailment and I'm hoping someone here can offer some guidance. In order to communicate on, say, 3.595000MHz, I need to tune my rig such that the frequency display reads 3.595250MHz. Having listened to my own transmissions on a websdr station not far away, I've verified that the 250Hz offset produces a good signal on the desired 3.595000MHz. Shifting to 40m, the offset appears to be 500Hz such that, to achieve comms on, say, 7.160000MHz,I need to set my display to 7.160500MHz. On 20m, although I haven't verified quite as methodically as for 80m and 40m, it appears that I need to set my display frequency a whole 1kHz above my desired frequency. That there appears to be a mathematical relationship in all of this, I suspect that some simple might need to be adjusted. But what, I don't know. For the record, there is no clarifier/RIT in play. I know I can use the rig without trouble by remembering to dial higher, but I'd like to get the rig back into line as it is otherwise in mint condition. Any clues would be much appreciated. Thanks, Mark VK2MOH

After digging into hamlib a bit, I've discovered an executable that will act as a virtual "translator": it will make your rig (FT-980 or other) appear as a TS-2000 to software programs trying to interface to it with CAT. This means that if the SW supports the TS-2000 ... it will at least partially support the FT-980. The software does NOT have to use Hamlib ... this translator is an independent program that will translate the raw "serial" streams en-route. Caveats: 1. I have tried it yet. 2. It involves setting up a virtual com port. In Linus this is pretty easy. In windows it is more involved. 3. You have to install Hamlib on your machine. 4. Because the Hamlib FT-980 backend is Alpha, current functionality is very limited (frequency, mode, memories). We will hopefully address this ... But ... I think there is great hope that a huge array of software might be available for use with our venerable FT-980 rigs. The TS-2000 is very widely supported I believe. -Mat -- -Mat Breton, N8TW

HI, I buried the following enquiry in another thread so thought it best to bring it to light in its own thread... Operating my FT-980 on AM for the first time this weekend, on-air comments suggested that the rig has a modulation issue. With Mic Gain at max, people commented on poor modulation. I can’t get any action at all on the ALC meter in AM and need to almost shout to get it moving on SSB. My first thought was the 0.33uF capacitor but, checking the circuit, this is switched in and out using the Tone Switch. Switching from "1" to "2" made no difference. Could it be the microphone cartridge? How would I test it? Online searching for information revealed very little, it seems this particular microphone (MH-1B8) was not widely used. Any clues on testing the microphone, sourcing a replacement cartridge or other avenues of enquiry would be appreciated. This post on QRZ.com includes photos and a circuit for the microphone. If it’s significant, the unit was built in 1985. All the best, Mark VK2MOH

The next time someone takes off the IF PCB, could you snap a high-res picture for me? I'm trying to check to see if a jumper on the back was put back on the correct pads ... doesn't seem to match the schematic. No rush ... just keep me in mind ... -- -Mat Breton, N8TW

Anyone else in the group using this combo? I dragged my tuner and FIF-232 out of storage today and along with one of my '980s, set it up for FT8. That rig and tuner ensemble work MUCH better than other contemporaries of the period (and even a few later rigs such as Kenwood's 9x0"AT" equipped models) . One fly in the ointment: With the tuner set to "auto", it appears that some bands won't auto-select under control of the radio. Putting it in "manual" mode, band switching works properly - so this indicates the CPU and switching logic local to the tuner is in order. I tried two different interface cables and verified connections for each. This leaves the isolation diodes between the remote connector and the CPU. I'll post a reply with results of testing/replacement when I dive back into the unit in case someone encounters the same problem. 73 - Fred, N8YX

Guys, Is anybody in this Group using FT-8 i.e. WSJT-X software? If so, I have a request... further assuming that an FT-980 with a CAT interface is handy... My goal is to verify that WSJT-X actually supports our radio. It is listed in the pull-down Rig menu: I actually have tried various options for the PTT method, including VOX, but TEST CAT simply times out no matter what. FYI, I have tried three different FT-980s. None of them responded. So the obvious question is whether all the radios have dead CATS in them or.... my USB->RS-232 interface is at fault... So a quick hardware description on my end: Dell Inspiron, i7, 32 GB RAM, up--to-date Win 10. The interface is FT232 chip based and the FTDI drivers are installed correctly. To prove that, I used the same interface with an added TTL-RS-232 level translator and connected it to my K3. With the required ELecraft settings, the radio and the program work as expected. The interface alone appears to be OK then. To talk to the 980, I am routing the RX and TX lines from the UART directly to the CAT port. Some old CAT circuits show an open collector output for the TX.. in my case the output is TTL driven. Could that be the issue? And, yes, I triple checked if the TX and RX lines are connected correctly... Thank you for reading this. 73 and Happy Holidays to All, Wald N4PL

Hi All. I'm new here, so be kind....... 8-) I've got two 980s - one of them was my first solid state rig, bought new in the mid-80s and the other is a donor rig I got hold of for a song some 20 years ago. I seem to remember that when the rig is set to the 10m band, and certain pins are taken to GND on the ACC1 socket, the frequency display could be made to display 50 / 144 / 432 etc as the 10m band was traversed in 500KHz jumps. The rig stayed on 10m, but displayed the desired transverter frequency 'band'. I cannot find this info documented anywhere however. I seem to remember reading about it in an RSGB RADCOM magazine (probably within the review of the 980 by G3SXJ I think his call was) but even then I don't recall a source for the info being stated. I can't see anything mentioned in the 980 manuals...... Does this ring any bells with anyone or have I been sniffing the PCB degreaser a bit too much.....? 73, Phil Smeaton G0HSS / VK4BAA / VK4KW
