sBitx antenna-first warning
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

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

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

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
