Welcome to the new members of the 301 group!? This is the place; all things Yaesu 301.? You might want to take a minute to introduce yourselves.? This is Rex, K0KP located at Fish Lake about 15 mil. NW of Duluth, MN.? My FT-301D was purchased new by me back in 1978.? It is still one of my favorite radios.? Not too long ago I took the time to replace all of the electrolytic capacitors in the rig.? The job wasn't too bad really, but did take some time.? This did fix an intermittent RF power problem where after a few minutes of operating the power output would start to drop, I suppose one of the electrolytic capacitors had become leaky.? This had been a pesky problem I had looked for for many years.? Now the rig is completely 100% up to spec and looks beautiful.? I run my digital version with the original Texas Instrument "TIL" chips in the digital readout.? Back when the radio was new I ordered a few spares which has allowed me to keep mine operating with all digits completely in tact.? For those that might not be aware the TIL display chips have a habit of going bad and are now pretty much unobtanium.
For now that is it for me, like I said if you haven't had the opportunity to introduce yourself please take the time to do so.?? |

Well just lets follow the the request from Rex, I'm Kees (in a call pronounce it as a case in a court of law), PA1CJT, located in a small town near The Hague in the western part of the Netherlands. I purchased my FT-301 (analog) just recently due to the fact that my eyes getting worse and als SMD parts are getting to small for me hi. I own the FR-301 and also the FT-221 (looking nice next to each other) and also 3 FT-7(B) radio's and a FT-225RD. All with normal components so that I will be able to do some repair work what I never did before. I could be a frequently asker here.
The FT-301 (I already asked about it here) has one knob which was not fit (tightened) enough so I cannot tell what is 9 o'clock as mentioned in the manual by tuning reception. Perheaps someone can help here. I still have some SMD radio's from Yaesu like the VX-6R, FT-1500M, FT-1900 and I guess some more hi. That is in a few lines lots of information.

Hi Kees and welcome!? It is great to hear from you and your setup.? I think the knob you are referring to is the Reject knob.? The knob controls a small variable capacitor, when the control is rotated the rig produces a notch which can null out an interfering carrier.? I don't think the placement of the knob is very critical.? You could just set the control for good normal sounding reception and set the knob for zero.? Then when you want to null out a carrier you can simply rotate the control.? The Reject tuning is quite sharp.? Hope this helps.? Have a great day Kees and thanks.

I'm Fred, N8YX. Owner of a couple complete and several "project" FT-301s (both analog and digital versions), along with all the station peripherals, an FT-221 and related accessories.
Vintage gear is one of the main reasons why I stick around the hobby - it's very enjoyable to restore and use yesteryear's equipment. I have several projects ongoing with the '301 line; one is to convert a -D model transceiver to the 8.9875MHz IF used in the FT-901 and similar rigs...the primary reason being availability of filters. Should that prove successful, another one of the "project" radios will be converted and a third turned into a receiver, albeit with extra filtering and interference-suppressing features. Lastly, an external DDS VFO for the first transceiver is in the works; this in an FV-301 style enclosure - with digital readout. (I'll be posting a "want" for parts for this at some point.) The last bit in the project queue was to figure out how to program an ID PROM for my FP-301D supply. I ran across Randy's (W7CPA) manual upload and saw the info therein, which confirmed my suspicions on what Yaesu did with the PROM. AFAIK, a 74288 will work in place of a 74188 - just need to see if either of my programmers will support the chip, or if I need to go buy one. 73 all. |

Greetings from Vk5LTD in South Australia. ?I have a FT301 ( analogue tuning). with matching power supply. ? The radio does need a proper going through but is operational. ? Power is well down - it is the 100w version. ?I'll be sure to check in with the group when I make a start on the 301. ? This model was on the cover of an early radio theory book an I admired it every time. ? I came across the radio with a batch of CBs on market place. It was in another town, too far away to easily drive and test - 10 hour round trip. ? I had some clips of it powered on but no other tests so I took a punt on it and offer was accepted. ?They dropped it at a business I had dealings with and some weeks later they were coming to town so dropped it in at the cost of a nice chilled white wine. ?
I also have a FT-901D and FT101E from the Yaesu stable. ? 73 from Oz |

Hi Oz -
Congratulations on the FT301 analog rig!? It will be fun to follow along with your restoration of the radio.? This is a very nice radio with one of the very best receivers I have ever used.? Good deal on the shipping of the radio, that sure worked out well.? I am sure you will have the rig running 100% in the not so distant future.? Welcome aboard to the group!? Please keep in touch. 73 Rex K0KP |

Hi Rex and other members.
I fancied a 301 back when they were new, but with a family and mortgage the money wasn’t available then. Anyway I have just picked one up at a junk sale so it’s going to be my bad weather project for the next few weeks ( or months)) it’s a pleasure to be working with proper components again, not just cubes of plastic SMDs. My set is not quite a basket case but will need a compliant realignment . Located in N.E, England and retired my call is G4DAX. rgds Dave. |
开云体育Greetings Dave.Last time I was in the UK I was working in a funny looking round building in Cheltenham. Enjoyed my stay working with scary smart UK chaps. The FT-301 is well designed. The ETON Swiss upgrades are wonderful. The big problem is the crystal filters that are failing and no way to replace. Best regards, Randy W7CPA On 10/23/2021 2:59 PM, Dave smith

Hello everyone, like some others here, the FT-301 line was an object of desire early in my ham life. I owned a FT-101E at the time (still do), but the FT-301(D) always was the best looking radio - black+gold trim - really (my Alma mater's colors). IMO, the 301 line is better than the Collins "Gold Dust twins" :). I was drawn to it because of its unique time in history, first 100% solid-state amateur transceiver, it had the modularity of the 101 line (unlike the FT-101Z - what was Yaesu thinking?), the availability of analog and digital readout models, modular power output models (S - series), all thru-hold devices and nice matching accessories. I <think> that this line also pre-dates RoHS (2002), so that's a plus as well, IMO.
The above is probably not news to anyone in this group :) Over the years, I've collected a lot of the series, some working, some not. My goal is to put together the entire line - similar to what Fred_N8YX has done. I even have a FP-301D in reasonable condition, I too would like to get the CWID working, but I have some different ideas for how to do that. I have 301, 301D(x2), FP-301, FP-301D, LL301, FC-301, YO-301, the infamous relay box. I also have a FT-221 and FT-221R (both currently broken and sadly, neither have the Mutek frontend). Some spare parts that I've run across over the years. I have 1 AM filter + CW, SSB filters.. What I don't have is the base microphone for the rig, I have not been able to determine what was appropriate base mic at the time - was it a YD-844 or a UD-844 or some other model? I also haven't been able to determine if the clock was available at that time. It's a shame that they didn't make a matching 160-10 amp for this line, if they did, it would have been complete. I guess the only real "problem" with these rigs (from what I've read) is that the output finals are very sensitive to high SWR and the protection doesn't work all that well, so blown finals can happen if not careful.? The display LEDs also overheat and die on the D model. As with most vintage gear, parts are an issue (TIL devices, output transistors and the usual stuff). So I have 1 rig that's likely going to be a donor rig, if needed (half of the display LEDs segments are gone). Over the next couple of years, my plan is go through and get everything working, aligned and enjoy it. I do dable with DDS for my Drake stuff (SPR-4), so a DDS, general coverage receiver in an FT-301 box would be really cool. But the effort is low hours right now, due to still working for a living. Kudos the guy changing the IF of the rig! That's going deep. Keep 'em alive guys! At some point (maybe we're already there) most operators won't even understand the basic concepts of how these old rigs work or how the new (SDR) rigs work. (or how anything works.. ( - watch if you can, you'll laugh and shake your head at the same time) Jim (NO2P) |

I have 4 good TIL 308’s (right three segments) that I bought off eBay for sale if anyone needs some. Gene N4FZ?

Another thing that might be done with a "stock" (9MHZ IF) '301 is to redesign the Filter Unit entirely, adopting a Jones approach such as Ten-Tec and Elecraft have done. 9MHz crystals are common and can be pulled a bit with the right combination of capacitances in series or parallel with them.
You could use varactor/resistor networks which are controlled by mode switching signals or use a panel-mounted control as a VBT of sorts. A TX-signal override would automatically adjust settings for AM or SSB audio bandwidth when the rig goes into transmit. Perhaps one can refit 9MHz Ten-Tec filters too. Just thinking aloud here. 73 - Fred, N8YX |
