Hello, it's KD8CEC version CEC 1.20 for Ubitx 234 i have received new quartz, so i will be migrate to V5 in a week or 2. i have to calibrate them nb: It's home made Ubitx. There is also some strange

John thanks for the headsup! 73 Lou KI5FTY

which software version are you using?

Hi Jerry, Pay attention, the title does not mention "ALC" but "AVC" Automatic Volume Control, just to clarify. In reality, the three definitions represent three different methods of regulating a

Sometimes S values do suggest "skip" zones when I listen, telling me which section of the country might more likely respond to a QRP-level CQ. Jack, W8TEE

A slight correction, or perhaps amplification: AVC (automatic volume control) is another term for this concept, and that is pretty much synonomous with AGC in my book.

The S meter isn't intended for the guy at the other end. Band conditions and a whole host of other things will affect the signal strength. The S meter is for the operator, it gives him/her something

hello, I tested the following thing. I’d like to change the 28,000,000 band to 26,960,000 that match the target frequency CIBIE. So I changed in the manager, saved > Ok I made a working stop of the

Loris, Thank you for your answer. I suspected it was a pb of this type. Actually my SI5351 is a module, and once disconnected, of course, the pb disappears. (no frequency in the BF section) For the

Amplifier Research did this in their RF Levelers. They used a minicircuits mixer as an attenuator using a control voltage. Vince - K8ZW.

You really need to check the output of these power supplies with a scope. I'm a cellular systems engineer at AT&T and our -48 volt charger outputs are really dirty. We have additional filtering

It's fine to go off topic, that's what a discussion does. Anyways, the ND6T AGC circuit is about as simple as that from WB8YYY, and doesn't depend on luck to find the right LED+LDR. Unfortunate that

Thats the objective of an “S” meter. (“S” stands for signal strength and its in db or mv). MRM

Hello Gerard, Have you tried to load a very simplified software on the NANO? I would not want the problem to arise from the verification cycle that the micro execute in the program loop ... The BF is

Hi, I respect that you see things differently:) 73, Bill KU8H bark less - wag more

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
