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: surprising CW sidetone value in uBITX Manager 0.11 #ubitx

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.

So you had to figure out that it was a VIA and not an unused plated through hole solder point?  I have never thought about that. It seems that many boards have unused holes for parts that later were not needed.  Are there any tip offs that a point on the board is a VIA?

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

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.

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

Mike KK7ER
 

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!

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

It is true, better warnings and feedback would be good. The suggestion that the uBIX manager is the best place to add the feedback is good. But, remember this is the output of one programmer. I'd say the amount of code he has produces at a high level of code design is remarkable. 

I'm sure he does keep track of the users' experiences with his code (like this thread) and as he can, prioritize these along with other needs, and makes an effort to incrementally improve the code. So, in that light, user feedback and suggestions are valuable to everyone. I've definitely expressed my opinion where I think something should be changed, but I know that those suggestions will be weighed against other priorities.

rOn,

I agree that uBITX Manager should flag bad values.  But this is not a user error.  It is simply the result of flashing CEC firmware on top of the stock firmware.  The stock firmware did not write the memory locations where CW speed and sidetone values are stored -- it left them uninitialized.  And apparently by design, the CEC firmware does not overwrite the EEPROM memory space used for user-defined parameters (probably to allow restoring the original firmware without losing settings).  I may be mistaken but this interpretation makes sense to me.

I agree. It's important to keep in mind what both Farhan and Ian have shoehorned into an incredibly limited address space. To me, the most amazing part of their efforts is how they managed to fit everything into a 2K SRAM memory space. After all, that's where all of the data ends up residing plus it has to accommodate the heap and the stack. I'm sure both want to hear users' wish lists, but I would not be at all disappointed if most of those wishes end up on the to-do list simply because there aren't enough resources left to bring them to life.

OK - Agree about leaving code alone that is already there in EEPROM.


But since I never run CEC code does the Memory Manger check your inout when you

do enter a bad value?

Re: uBITX No Power Output all of a sudden #ubitx

Get real?  I am 73 years old and have been building kits since the Heathkit days and every day I learn something new makes it a good day to be alive.  I am of the old school persuasion that there are no dumb questions. Most of the kits I have built lately have had unused holes but the kits worked and I never even thought about it.  Once I was sent a prototype board by mistake by a very reputable kit seller and it took a month of Sundays and the help of the board designer to figure that out and fix the board for me.  Another good day. St. Peter don't you call me as I have 10 kits that aren't finished yet.
