Re: Winlink configuration with the uBitx
I use the usb for cat control and do not have too much trouble. Sure it raises the local receiver noise a small bit, but its not enough to worry about.

Start with relatively low power, you can set that by setting the transmit gain on the signal link fairly low. That will reduce your chance of having radio frequency interference.
Don¡¯t connect anything at all to the raduino USB interface.? It is a very vulnerable point for radio frequency interference.
At this point you should be able to do the WINLINK transmit level test without any problem.
Pick any legal frequency and initiate a call to any WINLINK station, don¡¯t try to connect yet, just make sure he can get through a series of calls without crashing.? You need to be in the CW/digital portion of the band

If I remember correctly, the arduino being reset usually is caused by the DTR of serial port. You might need to find a way to configure the serial chip to not use the DTR pin. I have been meaning to look into this as well, cause each time I
start up wsjt-x, the ubitx resets.

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?

I just bought these but I can feel clicks (steps) while turning. Does this mean they send me a part that isn't an EC11?
What else do I need to search for? I prefer a North American vendor for fast shipment.
This is what I just received.

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!

Re: Using IRF530 outputs and 2N3553 drivers in ubitx
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?

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.
OK, but which one is "+"? ?

Re: ERF2030+ RF Power Mosfet Transistor, 30 Watt PEP per $1.00
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.?
