I actually was helped by another ham... this runs to the top of the L16... and the solder completed/continuity'ed.

Looks like my botch job wasnt a botch.

This was V4 by the way

Alwaus do what the book says, they may have slues you don't.
2) When I calibrate on a strong AM broadcast signal as suggested by HF Signals I get a different settings depending on the day. Also that setting is not always the best when calibrating on 10MHz or 15 MHz. What is the preferred calibration method?
Sound like you not zero beating or the adjustment is not being kept.

3) What is the relationship between the calibration adjustment and the BFO adjustment? Through many trial and error attempts, I find that changing the calibration setting also changes the BFO setting. Sometimes with large effect, i. e., from 11,055,500 to 11,058,800.
FIrst the Main cal must be done so that the actual frequency of the BFO is correct then you tweak that for best audio.

4) As a heads up, for those using CEC v 1.2 with Nextion 3.5 display, the config/read will display the current setting for calibration and the last setting tuned for BFO. However, if a calibration has been performed after the last BFO adjustment, the config/read will display the old BFO adjustment. A different BFO starting point will be displayed when ending Adjust BFO via the Settings screen.
With CEC and non Standard Raduino code consult the author of the code.

Relationship of Calibration to BFO tuning v-5 #calibration #ubitx-help

All,

I've been reading this group's posting for several months along with relevant postings for this topic...but I have some remaining confusion/questions.

1) What is the right order of adjustment: calibrate then adjust BFO or vis a vera? HF Signals says calibrate first.

2) When I calibrate on a strong AM broadcast signal as suggested by HF Signals I get a different settings depending on the day. Also that setting is not always the best when calibrating on 10MHz or 15 MHz. What is the preferred calibration method?

3) What is the relationship between the calibration adjustment and the BFO adjustment? Through many trial and error attempts, I find that changing the calibration setting also changes the BFO setting. Sometimes with large effect, i. e., from 11,055,500 to 11,058,800.

I noticed that the schematic included in your original post has a single 3-crystal filter while the one on GIT hub has two complete filters chained. Can you explain which is correct?

Thanks!

Re: Antuino 2.0

It appears there is still a lot of tweaking being done to get the Antuino where it needs to be for mass production and sale.

Is there a new target date for when it will be available to us (anxious and loyal) hfsignals customers?

not sure where the audible cliek comes from, but changing the encoder to one without clicks removes it.. plus you can move around the band much faster..

Many folks change out the encoder to one that doesn't have clicks. This is what I prefer, to each his own.  Here is an example of what I am using. You will have to get a 5v line to it but other than that, it works seamlessly. These are available lots of other places. You can also buy the original style encoder from an Electronics house with or without the clicks..

Re: Antuino 2.0

Ashhar Farhan
 

Rob,
we had to change the clock to 27 MHz (probably, i didnt edit the schematic properly) as the IF of Antuino is itself at 25 Mhz and the clock crystal would have created a spur right in the middle of the passband. The early Antuino had a 16x2 text LCD display, just 80 of them were made as a workshop project for our club's annual convention. After that, I felt it necessary to add graphics display. I chose a 128x64 LCD display as it provides good readability in the field (it is quite sunny most of the time here), The TFT displays didnt work too well and they drew a lot of current too. The existing Antuino draws about 60 ma when powered up. That will make it last a very long time from a set of six AA dry cells (At 1000 mA-hour rating, it means, that they can be operated for 16 hours continuously before the battery runs out).
73, f

Hi All,

Probabely i missed something. I see the schematics and I see the clock crystal of the SI5351  being in version 1.0 25MHz. and in the version 2.0  27MHz.
So there must be also something different in the SI 5351.ino file or so I think for the calibration. I'm not a programmer, but try to understand the schematics and program before building.

With ANT connected and volume at nominal level you maynot feel the encoder clicks, I suppose.

Tuning VFO causes a soft click with every step (regardless of step size).   It is exactly same regardless of Volume setting and sounds like a relay click.   In fact it sounds exactly the same as the PTT 'release' click, that is the relay click going from TX back to RX.

Is this normal?  So far my UBitx appears to be working OK,
