Re: A way to Check the audio SSB frequency response of your microphone.

-- Hi Mick, glad that you found my post on checking the mic audio frequency response helpful.

Setting the UBITX SSB audio up properly will only further add to the acceptance of  UBITX transcievers in  SSB Mode.

How could you make the bandwidth narrower??

Thank You Rob!!
Ive been fiddling with this for a while and never quite getting the VFO “perfect”. It was close but I was being told my audio was a little tinny. I found my VFO setting put my audio response at 1100 to 4200 hz. I’ve adjusted the VFO and now (with this generator tool) I can see my audio response is 512 to 2600 hz and sounds much better.

Your preference may differ; a slightly more high-ended audio response in TX can help with poor conditions, especially with lower-powered transmitters. That is, "broadcast" quality mic response isn't necessarily a bonus.

One may want to experiment, using a contact who has time to work with you or an SDR somewhere.

Re: Cw not working with straight key

Typo.  Should have read: I had a somewhat loose connection on my stereo straight key plug.....


Re: Cw not working with straight key

I had a somewhat loose connection on my att  as iffy key plug recently. It would key up my commercial rig fine but wouldn’t work on my v6 Ubitx.  I had used a cheap stereo plug  and the internal connection was poor, I guess just enough to cause my Ubitx to not key up.  Maybe try keying down the straight key while gently moving the stereo plug back and forth.  


Also, if found if my key contacts are dirty or dusty I can have keying issues with Ubitx.  


Hope you get this figured out.  I’m loving my v6 Ubitx for CW.

did you select straight key from the keyer menu?

Aaron,
Sorry, was trying to point to the original file location in case there was an update.  Attached is the PDF that I have.

hello,
Thank's for the answers
The view plays tricks on me, I saw a zero more. thanks for the explanations. I’ll do tests this afternoon

Re: uBitx v6 3rd party case

Vic WA4THR
 

Your choices are almost endless! Look on ubitx.net for examples as all earlier versions came without cases and many inventive solutions were found. I have used the plastic instrument case from Bangood for my V4, which can be had for as little as $8 including shipping, and I have managed to include a number of additional boards for added features including the Nextion display (same size as the touch screen with the V6), AGC, SWR bridge, power regulation, etc. A bit of a tight fit, but the case design is really neat allowing access all over. I used the same case for an earlier BitX40 and included AGC and alternator filtering inside for mobile use. At the other end of the scale are the case "kits" from Amateurradiokits.in which cost quite a bit more but are pre-cut and painted for the uBitX controls and display you choose. In between there is a plethora of commercially made electronics housings, waterproof cases, 3D-printed, and hand formed choices. Have fun designing what YOU want!

Yes go with the toothpick idea because tweezers can act like launch control if you squeeze too hard, ask me how I know. :(

Re: Please explain to me how works the VFO's

Evan Hand
 

Gerard,
I believe that there is a typo.  Go back and count the zeros in the second capture you provided.

To answer your question, vfoA and vfoB are memory locations where the program is storing the values that the operator has selected.  Depending on which one is active, that value is used to adjust the internal oscillator (Clock2 for main frequency) which is APPROXIMATELY 45MHz + the vfoA or vfoB depending on which is selected.

So if the vfoA = 7.100200 MHz (7100.200kHz) 
Then the Clock2 VFO of the Si5351a will be set to approximately 7.1002 + 45 MHz = 52.1002 MHz

If the vfoB is 14.19735 MHz (14197.35 kHz) and selected then Clock2 of the Si5351a is approximately 59.19735 MHz.

Hope this helps.

uBitx v6 3rd party case

David - WB7DWF
 

So I have a uBitx v6 WITHOUT a case - any suggestions for a 3rd party case that has some room for adding some other stuff (power protection, CW filters, anything else I can think up, etc)?


Re: Please explain to me how works the VFO's

Everything in the tabs is compiled and uploaded as part of the program. The compiler generates the code and the linker stitches everything together correctly. All of this is hidden behind the IDE.

By the way, silly question about the Arduino software.
When uploading, does it only take into account the selected tab or does it do it for everything?
If it only takes the selected tab, then I will miss a piece of program!! LOL
My faith, interested to know anyway.
