FT-301 alignment: Band pass filter adjustment results
I've been working on a 301 that I recently purchased. In nice shape physically, cleaned up really well. Gave it the "deoxit" treatment, now going through some adjustments. First thing I wanted to look at was the band pass filters. I followed the alignment instructions in the manual using a sweep generator / o'scope. Seemed to go okay, but I was curious was the results really looked like. I used a rigol spec. analyzer/tracking generator to sweep the filters and the results initially were okay, but I tweaked them in. It's a lot easier and faster looking at the results in real-time. Photos have been uploaded.
I'll try to capture/upload more results of various alignment steps as I go through the unit. Enjoy!

Gene N4FZ There's a guy in canada that sells parts for ft-301/d, as long as you're not looking for 2sc100 finals or TIL306/308 LED displays, which are unobtanium (I love that word, it says so much in just one word...)
What parts are you looking for?
At some point I may have a "parts" rig, but so far, I've been able to keep mine running without canabilization..
He's winding down his business, but still is working w/ FT-301 stuff. I've purchased crystals from him:
His name is:

I have no relationship with this business or him, except as a customer.

Anyone have spare FT301 parts?

Hi Randy,
I have a source for the four NYLATCH on the top of the 301 lid. It seems that the 221 takes the taller versions. Also have a source for the cabinet screws as well. These screws are the same for all of the 301 line. If you don’t use a JIS (Japanese Industry Standard) screw driver you will mess them up.

Re: Yaesu FP-301D PROM Generator
Hi Carlos,
I plan on building the programmer from from a guy online that was designed specifically for the 74188. It’s important to follow the IC manufacturers programming/burning guide lines.
If you come across an FP-301D I’d like to purchase another one.
Regards, Mike

After some browsing, I could find many DIY 74188A PROM programmers that can be used by those not wanting to modify their FP-301D.

I think the easiest way to do it would be by using an Arduino Pro Mini or Nano, but if one doesn?t mind modifiyng the accessory, the same basic hardware could be used to build a brand new add-on CW ID capable of replacing the entire TTL circuitry of the original ID?er.?

Just a thought...

Re: Yaesu FP-301D PROM Generator
Hi Mike, the info on the programmer was me Jim - KA3EBX. Randy helped me when I was trying to program my prom a couple years ago. I originally used hobbyroms in Canada as Randy recommended to burn my 1st prom then I tried it myself and it worked. I've done a few for myself, my club as well as few other hams. Quoting michael.kohlstadt@...: Hi Randy,
Thanks for getting back to me. Yes these cost a lot but they do the job. I’ll give them a call to see which units are capable of handling the 74188.
Thanks again,
Mike

Hi James,
My mistake this is the only one. I think that Foxtrot Tango was one some years back.

Re: Yaesu FP-301D PROM Generator
I put up the Japanese manual in FILES with English
PROM programmer info a few years ago and found a antique video
game dude to program it. All those old video games people have a
programmer it seems.
