V11 40MHz?
Hello All, When I moved from V11 to V12, I did not take apart my V11 boards, or cannibalize them in any way. Now, I might have a use for them. I've been a ham since 1970, and I have a weakness for the

Re: More T41 V12 Results
Bill, I think this makes a lot of sense to design this way when others are building and operating! I appreciate you commenting, good to know that was the mindset in your design. I've been trying to

You can decline granting trademark rights under the license.? So, you could require they submit a test copy to you if they want to call it the T41, if that name was trademarked.? That has costs

Re: Adding PTT to Main Board
a bit strange, as Dr. Bill says they (PTT In Mic IN) should be isolated. When I had PTT In tied to Mic In going to TRS jack PTT did not work. After remembering Ver 10 and Dr. Bill,s hint I ran Mic and
Re: Adding PTT to Main Board
That's strange! I did the opposite! PTT in was tracked to J16 Mic_In - Ring and I cut the track. John, G0SDF
