There's an SP-980 on the auction site at the moment. Note there are two versions of the speaker, as with the SP-101, 102 and 901. One has a phone patch built in; the other, a switchable passive audio

Sure will Mat. Next time I’m at the station I’ll look into it and let everyone know what’s what. I’ll check that it is still functional etc first! Phil Sent: Monday, 13 September

If you do, broadcast/ping to the group. The "paper" speaker that Yaesu used appears to be high quality: see the article I put in the files section. The impedance is certainly matched. -- -Mat Breton,

well would be nice to have one. Wonder what shipping would be to La from VK? Randy ________________________________ Sent: Sunday, September 12, 2021 5:13 PM To: [email protected]

I had no idea that the speakers were rare. I have 2 of them…. Maybe I should put them onto eBay – I don’t tend to use them……. Phil VK4BAA / VK4KW Sent: Saturday, 11 September

Hi, ?? please note that the SP-980 and the SP-102 (or 767) are not? compatible in size since the FT-102 (or 767, 736) are lower in height respect to the FT-980, even if the front panel's designs

One of the greatest analog receivers ... I don't think Yaesu had anything like it until the FT-1000 came out a decade later. And the PA is so overdesigned you can operate continuous at 100W. The

I was given a ft 980 in pieces and after cleaning and replacing a 20 pin IC in PLL I have it working great! What a rig. Bought a MD1 for it, and now need the matching speaker. I think I want to keep

I'll be running my FT-980 on RTTY for the NAQP contest this weekend. I use AFSK w/ fldigi via a SignalinkUSB interface. The setup works well (also use it for FT4/8), and I have no fear running the

Hi Fred, thank you very much for your comment. I'll consider that when I'll start the tx review! I'll follow the steps present in Service Manual but I also want to check the dynamic behaviour of

Getting back to this one (after spending time on other projects, radio and real-world alike): If I let the rig in question thoroughly warm up, it won't tune at all in either direction with the VFO -

Enrico, I have four '980s. All of them exhibit a condition wherein a carrier of, say, more than 30w will cause ALC saturation - and as a result, output power will creep up to the maximum set point

Dear Mat, sorry I was very busy and weren't able to reply to you soon. I wasn't able to find the data sheet of the TDK Caps, but your proposal seems better than mine (tantalum caps)! Please note

Wow: there have been a few "douzies" submitted recently. This is another one that doesn't trigger anything in particular: I haven't seen anything like this with my one 1983 rig. BTW, it performed

Got one with an interesting problem that I thought I'd throw out to the group before digging into it: The particular '980 in question was my main 20-40-75M rig for a number of years, where it's

I wonder if I could drop in an MLCC ceramic in place the electrolytic: TDK?FG14X5R1E226MRT00 for example would have negligible ESR and parasitics well past 100MHz. Definitely added to the list to

First off, congrats on having TWO FT-980's! Wow: I watched this video twice. I haven't seen this one before.? I'm going to have to mull this on over. First off, I'm not sure why the FM VFD segment

Hi Mat, Here is a quick video clip of the actual issue. https://youtu.be/K55xHA8SkGo I did notice that while making this video clip, the receiver seems to switch on when the mode switch is in the FM

Hi Mat, thanks for your kind reply. Sorry for pictures not being uploaded, I'll try again right now. I do not have VNA, I'm thinking to buy NanoVNA because I read very positive reviews, but now I use

Hi Enrico, I'm very interested in your work. Unfortunately your pictures did not make it through. Can you link through dropbox, or maybe try again? Do you have access to a VNA (like a nanoVNA)? It
