Re: uBitx Modulation only lows no highs in frequency response

The carrier oscillator is an incredibly important adjustment that greatly affects transmitted audio.  This could be useful.

YO2LDK on an IC-7000

I too would love to be able to remote head an IC-7300 with a Nextion for mobile operations.

AutoKey, Memory Keyer, operating CW via CAT #ubitx #ubitxcw

After watching Ian's video (https://www.youtube.com/watch?v=a4au90STsdY), it was quite easy to establish control of the uBITX via CAT using Fldigi.  In the video, Ian demonstrates keying the mic via the Fldigi TX button.  Is it also possible to transmit CW?

From reading the Fldigi docs, it looks like Fldigi simply keys the mic and sends CW via a generated audio tone sequence over SSB.

After searching the BITX20 archives and Ian's blog site for a while, I see mentions of AutoKeyer and Memory Keyer but cannot find details anywhere.  Is it possible to generate and send CW from the uBITX Arduino given a character sequence over CAT / USB cable?

Sorry for the ignorant questions.  I got my novice license 42 years ago but have been mostly inactive for the past 30 years.  I feel like Rip VanWinkle!

Parts on factory PC boards are 99 percent of the time outlined by silkscreened legends.  VIA's are unmarked.  Hole far too small for a component lead (30 gauge wire barely fit the hole), what would you think?  Get real.

Following your thoughts Mike, The user's error should have been noted in the Memory Manager.

I think this design choice is reasonable given the constraints.  The design principles involved seem to be:  1) don't overwrite the user's data in EEPROM unless the user tells you to, 2) don't accept user-defined values that would lead to obviously bad behavior, 3) make the transition from original/other firmware to CEC firmware painless and easily reversible.

Another design principle that you and I seem to value is that of informative and actionable error messages.  But that has to be weighed against the others.  Some of us want to know all the details (thankfully, we have access to source to figure them out!).  I suspect that the vast majority of folks just want it to work without thinking about firmware details.

Re: K5BCQ click fix 2nd generation installed #ubitx

Lacking a leaded capacitor in that general range, carefully touch a wire from the top of your new C50 to the I/O trace while in receive mode. This bypasses the new board. If it restores audio then you know if the rest of the receiver is still functioning. In that case, check the gate of Q3 to ensure that it is getting the RX voltage. If it is, then either Q3 is bad, R2 or R4 is shorted, Q2 is shorted, or some unimaginable other combination of bad things.
Looking at the top of a 2N7002, with the single pin (that's the drain) away from you, the left pin is the gate, the right pin is the source.

If there is no audio  when you couple the audio past that gate then we can assume that your replacement capacitor is bad or that the receiver chose that moment to quit.

Having a little outboard audio amplifier would provide you with an excellent tool. Just a good blocking capacitor on the input will allow you to probe from product detector to speaker.

Re: AGC manual rf gain versus KD8CEC ATT rf gain software

Gary, after listening with AGC does it seem you still need manual RF gain control? I'm happy with AGC only. I would recommend the S meter connection off the AGC board and KD8CEC software though.

AGC manual rf gain versus KD8CEC ATT rf gain software

Gary Hanson
 

While waiting for my Nextion display to arrive, I completed the AGC kit and was considering whether to add the manual RF gain as suggested by Don, ND6T. I also plan to upload the KD8CEC firmware and noted it has the ATT software RF gain control. Am I right to assume that I do not need to do both?

The manual Rf gain limits the signal at the front end and the ATT software shifts the signal in the filter. Any advantage of one over the other? If they both accomplish the same goal, then it comes down to twisting a variable pot knob versus using a touch screen slider.

Re: Source for female connectors/pins/manual crimp tool?

Radio-control aircraft enthusiasts use the same types of crimp connectors, so a local hobby store probably has male and female pins and a crimper.  The crimp tool linked to below should do the job and it won't kill your ham-project budget.

https://www.showmecables.com/d-sub-crimp-tool?gclid=CjwKCAjws8vaBRBFEiwAQfhs-BmOdBAvHw7fnPZd1Wnhm2dWCRCMJ8UI-yR39lF6crX_4uVqluOTJRoCSFcQAvD_BwE

I used a similar tool for my uBITX project.  For female crimp connectors that attach to 0.025" square posts on 0.10" centers, use the Jameco Electronics part #100766.  The small tabs crimp the metal wire, while the larger tabs crimp the outer insulation and provide a strong physical hold in case you pull too hard on a wire.  Jameco also sells the connector housings for from 2 to 36 contacts.

Nextion and the Icom7300 #ubitx

Bo Barry <bobarr@...>
 

Completely off topic, almost. But this is where our genius Dr Ian hangs out.
As we are learning, the Nextion is a computer all by itself!
I saw a YouTube by YO2? where he had his helping the awesome Icom7300 along!
I'm slowly learning from Ian's work and will put that project on my list.
Gotta do the RTTY contest at 2pm Eastern today first!

Well if one goes out of his way to check an error condition and finds it you should

at least let the user know!  Probably should write the substituted value into the EEPROM.

This is to error correct extreme values that may be set by the user.
If the value is between 100 and 2000 it does nothing!

At 21/07/2018, you wrote:
I think I see what is going on.  For example, in initSettings(), the sidetone value is getting read from the EEPROM:

EEPROM.get(CW_SIDETONE, sideTone);
 
But later on, it is getting overwritten if the value is not "sane":

if (sideTone < 100 || 2000 < sideTone)
  sideTone = 800;
 
So that explains why uBITX Manager is showing bogus values and yet normal values show up on the LCD.
