Y'know...with all these Bitx's out there...we could have our own weekend QSO contest! I can hear it now! "See-Kew See-Kew Bit-Ex See-Kew Bit-Ex..." -- contesters could exchange RST report,

I am creating a Bitx40 design metal enclosure box. ?Would be nice in this thread if you share the outside diameter of the knobs you chose. Also the outside diameter of the tuning control and volume

Just got my BITX40, just checked the serial number and it reads "O317". - Rich WB2GXM

The number is like this : AB-xyz The xyz is the serial number within the batch B. A is not a number, it is the initial of the tester. 'F' is for farhan, 'U' is Uma, etc. - f -

Hi Randy, Here's a bit more data for your list 73, Andy KG5RKP ?869 ?11/19/2016 ?11/22/2016 ?12/19/2016

Kind of like Kung Fu. ?Except this is used to do battle with Wiki's, not Kung's.

An ancient Polynesian boat building technique as in Kon Wiki.... J/K, it's is a play on Google Fu which is a measure of a person's ability to find things on Google. James

Found this on eBay item number: 271695585529 - [image: GEC-PLESSEY-SL611C-RF-IF-Amplifier-Wide-AGC-Range-50dB] - [image: GEC-PLESSEY-SL611C-RF-IF-Amplifier-Wide-AGC-Range-50dB] 10

or you could do worse than check out the IF AGC (and S Meter) approach used by Eamon Skelton EI9GQ in his various rig designs. A google seatrch will find them. I intend to use one of his designs,

What’s Wiki Fu?

Hi Not really sure. These are the numbers that I have collected. Randy, K7AGE BITX40 Deliveries – Randy, K7AGE 3/8/17 SN Ordered Shipped Arrived Num of Days VE3MIC 412 10/24/16 11/17/16

The audio amp with AGC as seen in the uBitx could be a good addition to the Bitx40. ?That amp will have less distortion than the LM386. ? If you want to know what's involved for really good AGC,

hi all, The SL621 works from the audio but controls the RF/IF. It has fast attack, to reduce the signal, a longish hang time to cope with inter-word/sentence gaps and then rapid decay to rapidly

Hi, On most discreet AGC circuits tis a Diode that feeds a resistor capacitor pair, it is the time constant (t = R * C ) that determines how fast or slow the AGC will work, it would be easy to

Why not use a NE570 compressor as a AGC ..?? Regards? Marc 'Gw0wvl'.. Sent from Yahoo Mail on Android

Probably W1AW code practice. Mine did the same! 73, Bob KI0G

Nice. I just heard today that these little boars are antennas themselves! How was the audio with an antenna? [email protected]> wrote:

I took my new Bitx40 out of my shack to show my wife right after it was finished. As soon as I hooked it up to a 12 volt battery it came to life and I heard real slow morse. So slow I could follow it.
