A bit of 5 min epoxy to hold them together tightly is all I would do.  

Just bits of metal suspended in ceramic/resin.

Thanks!

Have you noticed any cross-talk caused by the cat (USB data) connection to the RX audio?

Re: KD8CEC software CW Question

 

Hi All,

Here is another option to add paddle key to same port straight key. 
by soldering resister 10k & 2.2k to stereo jack.

I don’t understand the comment that the resistors should be at the paddle end of the connection.  Maybe someone can educate me.

So, the 4.7K is removed and the 2.2K is soldered there with the 10K on the Ring?  Also, even though I use my right hand I work a paddle backwards - dots on my thumb (left paddle) and dits on my forefinger (left paddle).  I didn't know the "convention" when I got my first set of paddles so I just hooked them up, backwards by accident, and learned that way.  So I guess I need to put the 2.2K on the ring and the 10K on the tip as I see no software "paddle reverse".  Will that work OK?

There is a nice AGC implementation using  mic compressor chip SSM2166 in Polish SSB transceiver kit "Omega". We can try substituting the AF preamp with a module from  Ali.. (baba..) and his band of...!!!

Re: Debug question regarding FT8 and KD8CEC cat control #ubitx

Tom,

Yes, it is necessary to have an audio path to/from the rig to the computer soundcard.

The CAT control can change frequency, and exercise the RIT command, bit that is all.

You still need an electrical connection to the rig to get the audio in and out,
then configure WSJT-X to listen to the correct sound card or audio interface you
are using.

Rod KM6SN

Basic question regarding KD8CEC cat:

Does this USB connection carry the RX and TX signals needed to eliminate external TX and RX circuitry to mic and speaker connections? 

I've been working through Ian's basic instructions on his website.  I'm able to control my ubitx fine from the wsjt-x via the KD8CEC cat.  Receive on the radio draws about 160 ma while PTT draws about 600 ma.  But I get no decode on the waterfall with the ubitx volume turned all the way down.  If I turn the volume up, then the mic of my laptop pics up valid FT8 QSOs. 

If I can confirm that I don't need any external circuitry, then I'll debug the wsjt-x and find the correct settings to make the cat-only connection work without external audio.  If instead, my understanding is wrong and I need external ciruitry even if I have cat via USB, then I'll follow up and build what ever I need. 

Thanks in advance for input!

Re: KD8CEC software CW Question

Bill Carpenter
 

Ron, you got my attention!   I switch my Bencher paddles between several rigs using a home brewed switch box so not sure how having those resistors on the paddle end would work. But I also have a K1EL keyer I use with my vintage rigs that is in that switched system that I am using with the uBITX right now so I really don't need to use the internal keyer.

Thanks for the help though!

Re: KD8CEC software CW Question

You need to series up the two resistors AND retain the pull up 4.7k resistor as shown in the photo.  If you are using both a paddle and straight key (like me) you will need two jacks

Re: KD8CEC software CW Question

NO NO NO NO.   The 4.7k should NOT be removed - it is required to pull up the key lead.  Removing it will cause the radio to go into transmit. 

The 2.2K and 10K resistors MUST be mounted at the paddle end of the connection - not inside the radio.  You are correct in putting the 2.2K on the ring and 10K on the tip to get reverse keying, but these MUST be at the paddle end of the connection.

The only external circuitry I used was an USB soundcard besides my CAT cable.
Main reason for that is that my audio jack was combined spkr/mic.
Wsjt-x advises to have the input volume at about 30%.
