Re: uBITX working, question about power, PTT pop, LOUD headphone output
#ubitx
Correction. PTT does nothing but the encoder button only exits the menu. The change to CW tone does not take.

If it's at 5000, I'll never hear it. That stupid time station is way too loud. I have tried it though with the plugs still in....only unplugging it from the LCD so I could raise it up. Still didn't hear it.

Re: uBITX How to wire key jack for paddles?
See picture for paddle wiring. Dot to ring dah to tip.
With code changes could be used for a straight key also assuming it has a mono plug. Read A6 at start up. If 5v run paddle code. If 1.6v run straight key code.

A dipole. Not going to change anything on it though. Not going to risk my HF rig over it. But, if I can hear the frequencies when we force it to a frequency, I should be able to hear it when it's tuning, shouldn't I?

Re: Help! I think I may have just ruined my 9 year old's Chanukah
actually, that pic
shows 5 caps and 2 resistors. I suugest that it would be
useful in these posts if you refer to components by their
numbers on the pcb, for example C1, C6 or C5 for those closest
to the Si chip. That will narrow down the effort for those of
us looking to reply, as it is our normal mode of referring to
them.

Caps look fine to
me. The two resistors can't really be seen from the at view,
as far as the solder joins closest to the Si5153 are concerned
but I would suspect that they are also OK.

Re: Help! I think I may have just ruined my 9 year old's Chanukah
When you have the raduino out of the case, is the display no longer connected?
If you have it connected and tune to a freq, then disconnect it that freq is lost unless the tuning pot is coming with it. It should be at either extreme 7.0 or 7.3 but I'm not 100% sure what the extremes are in that. So you'll need to check near 5.000 and 4.700 but that's not a guarantee.

I can't tell which frequency is displayed, but I have tuned it to a
frequency, taken it out, hooked it up to USB and then tried to find it.
I did 12,000 - displayed frequency. Never found it.
I did remove the caps. They look fine to me.

This is normal if ordered via India Post.? The radio is probably sitting at customs.??
You will be able to track it via the USPS website once it gets into their possession.??
This will take a week or two.

Re: Help! I think I may have just ruined my 9 year old's Chanukah
Oh, I thought you uploaded another one. The capacitor looks ok but that doesn't mean the connection is good. Load one of the working sketches then put the raduino back in the case like you did to test this one. Push on the caps and see if anything changes.
Something just occurred to me. Without the raduino connected in the case it's still going to do something. You just won't be able to vary the freq. So with it connected to the USB, see if Farhan's sketch works on 12.000 - whatever freq is displayed, or somewhere close to it.
BTW, did you remove the two caps on the main board so you can do upper sideband? If so, did they remove cleanly - without leaving a solder short or anything.
Vince.

The USB will not fit into the case attached. I have to do the sketch, remove the USB, then plug the raduino into the LCD.

Farhan's sketch does not work. Neither does Allards. In addition, the
signal on 25 mhz seemed louder than the one on 4800 mhz.
I tried Allard's diagnostic sketch and it keeps flashing PTT on and
showing TX even though PTT ISN'T on and the relays haven't clicked. To
make double sure, I unplugged the PTT button and I'm still getting that.
