All this discussion has me wondering how the tuner algorithm would compensate for component and measurement tolerances, and stray reactances. The calculations to convert magnitude and phase to L and C

Extremely interesting Bill, this could be of benefit in so many applications. 73 Garry. M0MGP

I'd like to order two of you.... Jack, W8TEE

I have been thinking about this for awhile. How does this sound: 1. The transceiver is set to a dummy load. 2. Key down initiates tune. 3. MCU determines frequency 4. MCU probes network with low power

There is one thing I would like to say though. You need to complain to those radio designers that use inferior techniques and parts… that design radio PAs that can easily be blown up. It’s just

Hi Dan, thanks for the note. Well… Switching a tuner in and out basis SWR is a very easy thing to do. The real problem is the tuning. If the SWR is 5:1 (and you are not using one of my

Bill, I posted this to the QRP Labs reflector: "There have been quite a few posts about ATUs and possible damage to QCX, QDX, and QMX finals. So it seems that someone should design and market a QRP
