Excellent Doug! It might get even more guys building them, if only for the coolness factor! I can’t hear any audio on my iPhone for some reason. Gary

Nice job Doug!!? Not being familiar with digital circuit design, I am impressed!!? Especially since this was done as a quick solution for a sight impaired ham on the forum. Very quick turnaround! -

I have completed the construction of another Si5351 FS4 replacement using the Adafruit I2C rotary encoder with a voice option to say the selected frequency for the sight impaired. This required

Marty and all!? The Parts radios were been sold on the first day of the listing, and picked up locally today! Sorry to take so long in responding, had some unpleasant distractions this week. Thanks

I looked this morning and my TR-4 has the arrowed dial skirt. Thanks, Barry - N4BUQ

Strangely enough, I had never heard anything about these components, when, yesterday I saw a reference to them on the Facebook VETE page and then something popping up here in the Drake reflector. Are

(Changing the subject line) I took another look and those caps are not grounded but connected across LINE and NEUTRAL through low-value resistors. I presume one of those is the resistor to which

*** Now aware. One exploded cap on the board. Luckily, I have the big service manual that was in the bag on top of the scope. Do these caps need to be anything special other than rated for 250V?

I could also use a AC-3 or AC-4 for my TR-3. This is on my list to look for at Dayton. Dave KC3AM

Hi Jerry, In case you're not aware of it, the 2400-series power supplies have line-filtering RIFA caps between line and ground as well as neutral to ground. Those are notorious for burning out -

I have an AC3 that I used with a TR3 many years ago. I still have both and they are on the list for restoration. From the looks of it, I already changed one of the capacitors and it worked then, but I

The arrow is with TR-3, at least. I also believe it was in early TR-4. The reason is that the 20m band goes “backwards” from the other bands, so you can’t use numbering around the skirt. The

I guess title says it all, looking for a c line at Dayton next week, whatcha got? K8cca

Hi to all! I recently got a TR-3 functional and hope to use it on some of the vintage nets. I'm now looking for a repairable power supply to pair with it (with or without speaker.) If you happen to

*** I almost bought that one. Actually, an upgraded 80Mhz version with higher sample rate. And actually...I DID buy it. But I sent it back; didn't even open the box. Why? I really needed a frequency
