Re: Feedback into T41
I used to have issues with my FT901 like that, CW would stick in transmit- RF in the shack. A ferrite slug with 6 wraps of the shielded CW key lead after it left the external keyer fixed it. My EFHW

Re: T41 V66.4 with Code Revisions
Hi Al, Ver 066_4 is a "Winner,Winner, Chicken Dinner" as a couple of T41 experts I know would say. I was able to calibrate Xmit IQ all bands without a problem using the receiver of my FT991A. Had a

Re: T41 V66.4 with Code Revisions
Roger, It is working correctly, but the readout is confusing. Next round I will fix it to read in dB, from 0 to -31dB. Thanks, Al AC8GY

Re: [AmateurRadioBuilders] RP Pico 2
You didn't read what I said. Each "page" (your term, not mine) is a segment of the display and only that gets updated. Jack, W8TEE

Re: [AmateurRadioBuilders] RP Pico 2
*** It should be more granular than that. If a new S-meter reading comes in, the Pico shouldn't have to update the entire display. - Jerry,KF6VB

Re: [AmateurRadioBuilders] RP Pico 2
