Re: Ubitx calibration help
Gordon Gibby
¿ªÔÆÌåÓý?Ah!? ?From your QRZ page you have an ICOM 718 exactly like me.? ?
One additional question:? are you able to make small changes in the code of the firmware that you've downloaded? like minor edits?
And which VERSION of firmware are you using?
Cheers,
gordon

?Can you give a little more information?
How far off?? Exactly how did you measure???
What did you do (give the details) when you tried "calibrating"??
Do you have accesss to an accurate existing receiver with a digital readout?
Cheers,

Need some advice on how to calibrate my ubitx. I have read the instructions. ?After several tries no success. Reloaded the firmware but freq is still off. Is there a better
way to calibrate?

Re: Tuning reversed issue
Jack you are right. I was thinking of this ubitx software center git.

There's nothing sacrosanct about the two analog pins. As far as changing sketches, whose sketches? If you write your own, it really doesn't matter. If you use someone else's, make a few typing changes and you're done. If you change the wires and then replace the board, then what?

reverse their positions. Then you can change sketches without

Tuner Kit Progress
¿ªÔÆÌåÓýSo for all the folks that sent me emails about the cheap auto tuner kit... i made some progress this week. ?The cores came in and i would a staggered set that total 20 uh. ?All checked out and tested. ?Very simple to wind. I decided not to use chip capacitors. ?They are expensive in the size needed to carry the current needed at large values. Silver mica capacitors are cheaper and easier for most people (like me with marginal eyes) to solder to boards. ?Plus the space savings is almost nil. I also found some cheap latching relays so the current draw stays low and the price of the kit stays in the sweet spot. ?This week ill design the discriminator (phase and magnitude) for power reading and tuning. ? More next weekend.?Dr.?William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ ? Owner - Operator Big Signal Ranch ¨C K9ZC Staunton, Illinois ?

The cases you see are for the bitx40.? They will have a ubitx case, shortly.? It has not been released for sale, yet.? It is supposed to be released sometime his month. Marco - KG5PRT?

Re: Tuning reversed issue
After Ron helped me get over the "stupids" and I finally learned how to properly compile & upload stuff to the Raduino, I now have Ron's mods running and he's fixed a lot of little annoying things (annoying to me anyway).? In between bricking & fixing the rig (all firmware, no hardware) I managed to make a couple of real nice 20 meter SSB QSO's and also a couple of 40 meter CW QSO's as well with it.
I heard a lot of RTTY (contest this weekend) and sure wish there were at least 5 more digital pins on the Nano.? Then it would really easy to implement a good CW Keyer and even implement true FSK for RTTY.? You'd still need a computer with sound card running something like Mako Mori's (JE1HHT) MMTTY program, but that would really work well.? Hardware FSK would be much cleaner to implement than tones into the SSB section.? As wide as the filter is, I'd be wary of the 2nd and maybe even 3rd harmonics of the tones being transmitted at the same time as the fundamentals.? That would really create havoc on the bands especially during a RTTY contest, not to mention incur the wrath of the FCC as well.

Re: uBITX for sale
Sorry Bob,
I already sent him the money - I usually don't get that lucky, but I was in my email client when Fred's message hit and it was too good to pass up.? I do have one coming in the 2nd batch from HF Signals but no clue when that will ship - LOL.?? This way I'll have the backup in case I brick the first one - (I did brick it learning how to compile and upload firmware to it today, but thanks to some nice off line help I have that sorted out now and I'm back up to normal.

All - turns out my ammeter was reading 0.0A on a simple D-cell and lightbulb circuit. Sorry for the noise!
