Winlink configuration with the uBitx

Josh Walton
 

After scanning the message archives, and finding a good bit of Winlink references, but nothing helpful for setting up WInlink to work with the uBitx, I thought I'd post a direct question to the group.

How do you best interface and configure WInlink to work with the uBitx?

My current configuration has failed:
uBitx with the CEC firmware V 1.061
soundcard interface directly with the mic and speaker jack (worked well with FLDIGI)
USB connected to raduino

Winlink setup under radio setup:
Select Radio Model: Yaesu  FT 817
USB
PPT Port: COM12, Baud 38400

When I do this, the uBitx just keeps re-setting at each PPT attempt.

I've tried soldering a 100 ohm resistor as Ian Lee suggests on between the V4 and Reset pin, just no luck

Any suggestions from the group?

It's almost certainly an Arduino Nano, with an ATMega328P chip. 
Not an STM32F103.

Kees,

Technical anarchy is sometimes a good thing, as it can result in breakthrough ideas. The price to pay is it sometimes causes head-spinning confusion, so it certainly isn't appropriate for structured projects with well defined goals. I don't think this project has well-defined goals and that's what makes it so interesting to me. There is a unifying philosophy though; everyone is trying to make enhancements to a common platform, the uBITX, and that platform is our de-facto interface standard. 

Vive la difference!

Is the reason for not using power MOSFET's in grounded gate the high drain-source capacitance? Looking at the IRF510 datasheet it looks like drain-source capacitance is higher than gate-source. Have I read that correctly?

Re: Encoder issue

Mike aka KC2WVB <rb5363@...>
 

Thanks for addressing this issue, Daniel

I would show a picture of the encoder but I removed it. It's only a few wires with yellow being a raduino ground that goes to the middle pin out on the three pin out side. Yellow also goes to the top pin out when viewing the encoder from its non-shaft side and the two pin outs are on the left side of the encoder. Red then attaches below yellow on the two pin out side and the remaining black and brown wires attach to the top and bottom pin outs on the three pin out side. Here it really does not matter because if you switch black and brown you get reverse direction but I placed black on top and brown on the bottom when looking at the encoder from behind and with the three pin outs on the right side. 

However, remember even if the push feature was perfect the rotary feature of the encoder was only operating half correctly. I.e. the pin out for the brown wire stayed at a constant high state while rotating the shaft in any direction. I think it was 4.54 volts dc.

The push feature under a voltage test was erratic, so much so that I don't really know how to easily verbalize its behavior. Regardless, I should have something other than strictly two items that read "Band Select" without an ability to select a band and "Press to Confirm" which is not meaningful if a band is not able to be selected when the encoder shaft is pushed inward. As a matter of fact there is a host of menu items that are selectable by the encoder but it is not presumably letting me in.

I am 99% certain the encoder that came with the kit was meant to be in the manufacturers trash pile and I will know for certain the encoder is the only issue my kit has when the new encoders arrive, most likely, Monday.

I am building the sister radio, BitX 40, now. It does not use a rotary encoder to tune the radio, rather it uses a 10K potentiometer. I suppose this is because it being a single band radio needs not a menu function that allows the operator to make changes. I am thinking, until the new encoder arrives I can probably get some tuning along the band its stuck on, ie 40 meters, by using a 10K potentiometer in lieu of the encoder. What do you think of the Idea??

Thanks for your interest.

Mike

Joe, W3JDR,

I think I would like a roadmap of all the "Raduino+" boards and firmware being worked on by a number of people and what each provides. Hats off to you guys.....but I am getting a little confused.

Design by committee is more difficult than herding cats, but using one of the inexpensive STM32F103 boards is a great design point when/if you have decided the Nano is out of gas......the best of luck to you.

If a Gerber file or boards can be provided, that would be even better, Joe.

The big stumbling block is again the firmware and coordination/support/committment of that firmware over time.

If it like my volume pot, it's just a switch. not polarized.

They do claim that it's a drop-in replacement for an IRF520 - so we can probably just go by the IRF520 data sheet. This means it's similar to the IRF510, but with double the input capacitance, but a slightly better junction to case thermal characteristics.

Re: Raduino CAD Files

That could work.
The uBitx could use some shielding, and around the Nano+Display is a good candidate.
Could filter the i2c bus to an  si5351 on the main board instead of filtering my UART lines into the Raduino

I've suggested having the si5351 on the main board multiple times starting well over a year ago.
That would remove the need for a Raduino entirely, just get whatever processor board plus display you want.

Though improving the electrical design of the Raduino to avoid the BFO beats might mean it can be
a drop in upgrade, no messing with shielding or adding an si5351 to the main board for current owners.

Simple solution. Separate the 5351 from the controller and display. Get that controller a ways away and it also has the benefit of more case options.

I got my hand on two years ago.  Looks and smells like a  IRF520 or its kin.
I think I paid 2$ then but it was nothing to jump up and down about.  It was
specifically aimed at CB radio power mods and takes advantage of the
narrow band interface typical of 2sc2166 and 2sc1969 CB radio designs.
Their datasheet is all about putting it in a Cobra GTL (and many other
similar Uniden chassis).

A crude measurement of one of them was Gate-source capacitance of about 870pf
the IRF520 is just a hair higher.

For a buck the worst you get is an IRF520.

In RF power devices the IRF510(and kin) is as close to the holy grail of cheap power
that is widely available.  Also anything in a TO220 case has a max power limit around
48W because the package does not get get rid of heat well.

Free Gerber files for sound card interface printed circuit board #ubitx #bitx40

Gordon Gibby <ggibby@...>
 

Well, I typed all of this out and never saw it again, hope this isn't a duplicate.
You folks helped me learn how to do DIPTRACE and now I have GERBER FILES free for a pcb that does a soundcard interface.   We use the $5 Adafruit USB sound dongle and bingo, we have access to just aboiut every digital mode.   40 cards made with an extremely expensive manufacturer--- now files available that can be uploaded to pcbway or any other chinese cheap fab shop.   Version 2.1 can be downloaded here:   https://github.com/ggibby1/SoundcardInterface2.1/blob/master/Version21.zip

A manual written for the previous card is still generally relevant:  http://www.qsl.net/nf4rc/SmallBookSoundCardConstructionManual2.pdf    The newer card is laid out slightly smaller (2.5" x 2.8" ) so that it will fit nicely inside Twinings loose tea metal tea-tins, which one of our ARES members provides us freely in abundance.    Make mic, speaker and ptt connections to bitx40 / ubitx  , set levels, should work very well.   The sensitivity of the VOX-type PTT circuity is determined by the resistor in the base lead from the Right sound card outlet --- 5K makes it quite sensitive,  47K will require full speaker output in general.   

We have a slew of this type circuit (it is not original with me) operating digipeaters / nodes / stations all over our county.   I was able to order 10 boards with ePacket shipping for $15.   Might be a good project for clubs / groups etc.   Eventually I'll upload a revised manual for this version.   Thanks for encouraging me to learn DipTrace!!!

Unfortunately their "datasheet" is more of an app note on how to hack various radios.
Near as I can tell, they haven't bothered to create a real datasheet. 
Good luck.

Route your +12V thru it. It's your on-off switch.
