Again...easy does it on the adjusting screw... Jack, W8TEE

Farhan: We used one of those in the another project. The voltage is adjusted with a small Phillips head screw driver. Just be aware that it is very easy to torque the set screw right off the board. It

25V Jack, W8TEE

We've tested the T41 with its 510s to 40W and nothing fried. 80-40-20M all can deliver about 25W without much effort. 15M is about 20W and 10M drops to about 13W. Like I said, it is what it is... Jack

We went through that same questioning process. Someone dinged us a few days ago because we're using the IRF510's. Out answer may be different because we are aiming the T41 at experimenters who may wel

Farhan: Think about it. In my mind, the smartest thing Ritchie did was to develop a language with no inherent I/O. He pushed all of that stuff into the standard I/O libraries, leaving the language unc

Al made one for high power. It's a thing of beauty: Jack, W8TEE

Curt: I've been reading a lot of posts about antenna tuners and I've looked up what they cost. Not cheap by any stretch and most are 10W max! As I recall, this one: cost me about $40 to build, but I h

Aaron: That is absolutely a terrific story! We need to encourage our young people to investigate our hobby and it can be tough sledding at times. I've told the story before, but at my club's GOTA stat

It's the native file format for Open Office, which is a pretty good substitute for Microsoft 365 with one exception: it's free. Jack, W8TEE

Chris: Most online vendors (Amazon, eBay, etc) use search engines that allow you to use just the item number (e.g., 4001275262743) in the search, so saying "AliExpress, 4001275262743) would take them

Hi John: Here's a cheap filter that can be used in the BITX20. See: “A Cheap and Easy BCI Filter”, CQ Magazine, August, 2016. This photo shows a version that I placed in my 49-er: Al, AC8GY, wrote a m

Neither does the Teensy, but they emulate it. No such thing on the RP? Jack, W8TEE

Farhan: Bear in mind that I've not played with the RP much, but why not add a button that reads a default setup from EEPROM? Jack, W8TEE

Really nice looking, full-featured, rig! Jack, W8TEE

I agree, Jerry. I put a "handle-spinner" on my T41 tuning knob. It stayed there for about 20 minutes. I went back to the old knob which just has a dimple on it. I also used an optical encoder in anoth

Mornin' Ford: Al and I have no control over the shipping of the T41 kit and they have not said anything to us about selling individual modules or boards. However, I don't see why they wouldn't conside

The Teensy is expensive compared to the Nano, but less than the full-blown RP. We chose the Teensy 4.1 for the T41-EP SDT because of its memory depth, fast clock, and high pin count. Jack, W8TEE
