Bill, I completely disagree. Whatever signal is present at the antenna jack is what the meter shows. Raj

HELLO TO ALL ! First of all, we all went a bit off topic! The question was about how to somehow govern the BF level without becoming deaf to any strong signal interfering in the QSO! The origin was a

If you buy a bunch, one AD8307 is under $0.50 https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=20pcs+ad8307&_sacat=0 Not clear if those are factory seconds, clones, or got

Hi Raj, S9 = 50 uV across 50 ohms. In the wild we rarely (if ever) have 50 Ohms at the antenna terminals. So there goes the baby along with the bath water. I do not know how to have a QSO a while the

Hi Bob, It's back to that volume control again. Earbuds allow me to run at a much lower volume. A strict interpretation of what you said about damage from using earbuds means that earbuds would damage

hello bob, thank you for your answer, but this does not solve my problem and I do not have an explanation on these 2 parameters in the ubitx manager.

hello, I will do some tests later this that: Noise reducteur and some AGC noise reducrer https://www.petervis.com/electronics%20guides/dynamic%20noise%20reduction/dynamic%20noise%20reduction.html +

Dean: You're absolutely correct about the work done by Pete. Stick him in a jungle with a penknife and some matches and he'd come out a month later with a 1KW xcvr...he does amazing stuff. Also, if

I was not talking about "calibrating" the V6, I call that something else. I was talking about "calibration" of the S-Meter/VU Meter at one point (volume level) and not assuming that it it correct for

Hi Loris - Let's see - one AD8307 from DigiKey is $14 - my handful of parts is about $3 - so if you want to save "a lot of money" use my design :)!? ? In fact the entire? Furlough-40 can be built

Curt, I don’t think you understood what I meant. Calibration is one thing, setting the BFO is another. what I mean, when you do. calibration, you look for the zero beat.Then you validate and have to

On S meter readings on 80's rigs: I would generalize from my years of fixing and aligning rigs that S9 = 50uV at the antenna. S8 = -6db of 50uV and S7 = -12db of 50 uV... below S7 the readings are

Bill, first of all, earbuds are a no-no. They damage the ears. Any device that is so perfect a seal to outside sounds damages the ears. First to go are the high frequencies thus the need for "old"

Hi Bob, The 'S' value in the RST does have some value but an estimate is good enough (and really all we can do). It is hard enough to pin down a number in a well equipped lab. A radio operating 'in

I just did Ooz, some days my hands are not steady.. Raj

Emacs!

Not really sure I got it. If It works well, please share the added schematics also drawn with a pencil on paper.

WOW !!! I had never thought about it ! it's almost brilliant! with a little time, as soon as the job allows me, I could try! Thanks Raj ... it's as simple as it is brilliant! 73 de IW4AJR Loris

Hi Dean all beautiful and interesting but, if your purpose is also partially commercial, you could save a lot of money on the circuit by using only one chip (eg AD8307 or NE604) taking the RF signal

Please post the circuit diagram also with your suggestions, that will helpful to us. VU2TDD , Biju
