Re: K5BCQ board layout and pinouts
It is not an AGC it is an antenna attenuator and good if you go to you will lose from 2 to 3 points S in reception, the system is not bypassable, even when turned off the MOSFET remains inserted in

Re: Interesting QST article
The uSDX is a development effort that has several evolving designs, it's not a single product like the uBITX V6. One cool aspect of it is that it uses a highly efficient class E amp not only for CW,

Question: Why do you call "AGC" a simple automatic antenna "attenuator" in this forum?
#ubitx
#ubitxv6
From my tests and from the measurements made, it appears to me that the best known "AGC" modification module is a very bad "ATTENUATOR" placed in series with the receiving antenna! Although I have

Re: Interesting QST article
Hi, It has been done over and over again from the time of earliest vacuum tube gear right up to recent days. It is a viable concept. See how you can use plug-in band changes on the newest gear:) 73,

Re: Interesting QST article
At some point I wonder if it would be possible to build QRP to moderate power TX stages at low enough cost, that rather than using relays or other filter switching methods for a multi band

Re: Interesting QST article
The uSDX, as originally designed, is a single band radio. It only needs one LPF. One of the circuit board kits separates the LPF and a few other nearby components onto a separate PC board that plugs
