KD8CEC now "working" on Raspberry Pi Pico
Just uploaded experimental support for KD8CEC running on the Raspberry Pi Pico. This required relocating the encoder, encoder button and PTT lines off of the Analog pins. They are now located (on Pico) on gpio pins:
? #define ENC_A? ? ? ? ?17
? #define ENC_B? ? ? ? ?18
? #define FBUTTON? ? ? ?19
? #define PTT? ? ? ? ? ?22
https://github.com/AJ6CU/ubitxV20
Gerbers for a corresponding Raduino with this pinout (v5/v6 support) is located at:
These Gerbers require the ability to solder surface mount components. In particular, the si5351 can be challenging.?
The original uBITX Memory Manager will *not* work with this platform. An alternative set of python based applications that provide backup, restore, and customizations is available at:
You will need to be "python" smart to get these alternative replacement for the uBTIX Memory Manager to work. They are not perfect, but should be useful. A GUI version that fully replaces the uBTIX memory manager is underdevelopment. At that point, I will also improved the packaging so that non-python folks an install it and use it.
NOTE: ALL THIS IS EXPERIMENTAL WORK! USE AT YOUR OWN RISK (AND ENJOYMENT!)

-I have output on cw mode, 8ish w on 80m varying through the bands
-the stock mic keys the radio as a cw key in the key jack and puts the radio into transmit when in the mic jack.? no output from the radio in ssb when speaking into the mic.?
-I have tried to operate the radio in ft8 as well with a signal link and a computer.? I can key the radio, but no output.?
-I have verified good connection at the mic jack on the board, tested the wires on the mic from the jack to the circuit board inside the mic.?
-I tried a c/b mic with a built in amplifier (using an adapter) that has a built-in amplifier and battery. no change.
-a quick look at the circuit board doesn't reveal any defects, or bad solders.
I originally thought it was the mic but if that was the case, it should have worked when using ft8 with the signal link.?
I am intending to use this radio for portable operation both digital and ssb, so having the mic/ssb working is crucial.? Not sure if I have a mic/audio issue or something else at this point.....
Thanks in advance for advice/next steps to test.

Re: Another battery question
Richard,
That Lossigy 20AH 12V LiFePO43 looks very interesting.
Includes a BMS inside, should be as easy to use as a lead acid battery.
Has 4x the Amp-hours of my Gooloo (though the Lossigy won't start my car!).
Web hits on "Lossigy" seem mostly positive.
A comparable Bioenno is nearly 4x the price.

Re: Another battery question
Yessir - the 10 Ah PSI cells are rated for 10C charge/discharge. One of the cell interconnects is a 100 A fuse, which can be seen in the photo.??Radios had their own fuses as well. The battery started as a test pack and has a couple sets of balance leads for different BMS and LVC devices. The bench-top spaghetti monster. hihi  On Sat, Nov 26, 2022 at 12:32 PM, Jerry Gaffke wrote:

So about the same as the RC battery, he charged with a BMS, and was careful not to discharge too far.? Discharging to zero might ruin the battery, but would not be dangerous.? Doesn't say if he fused it to limit the maximum current, but that's about the only additional safety measure I'd recommend.

Thanks Don. I'be only flown fixed wing RC, so am not familiar with how powered lift devices are managed. The ESCs I've used reduce or cut power to the motor when the battery gets low. Since servos are connected to the battery directly, they continue to function after the prop stops spinning. It makes it easy to glide back for a battery swap if one loses track of time.

Hi, Was doing some more reading on RigPi. Here is a page that talks about how the internet audio works in RigPi. It looks like to transport the audio over the internet, for remote operation of your station, RigPi is using "Mumble Voice Chat". Here is a link to Mumble: Apparently gamers like this protocol to talk to each other because it has low audio latency. This may be a step up to a more modern web/browser friendly protocol. I believe echo link, for example, is based on older VOIP protocols. Although I believe there are now browser clients for VOIP. I'm not a VOIP hater. I ruin my own VOIP server on AWS for one of my phones. Tom, wb6b

The RigPi software should let you do that. The source code is supposed to be out there, somewhere, if you want to modify it to use standard USB sound dongles. Otherwise you could look for a sound board for the Raspberry Pi that uses the same chip as the precompiled RigPi firmware uses.? The standard audio software in the Raspberry ?Pi should let you route sound to and from a headset/speaker and microphone to the USB sound dongle you have connected to the uBitx. There are some Raspberry Pi Linux audio patch cord apps out there, but I have not tried them out. The RigPi and the open source ESP32 sound and sound over the internet library I linked to previously could be of help if you are going to create your own audio software application. Maybe there are some folks in the group that have more information on remotely controlling rigs and transporting the audio across a network. I've been studying this subject, that is why I just happened to have some links. ProxMox... Interesting, I just ran across that program and was up all night the other night installing it on a used Lenovo ThinkCentre computer I got a good price. ?SmartDrive reports the hard drive in it has 37,000 hours of use, so decided to put a new drive in it, though. The log message was not too subtle. Because of the hours, It actually suggests "now" is a good time to make a backup everything on the drive. I manage production systems on AWS and it will be nice to have a very tiny version of a "remote" management system for virtual machines on a machine (or two) on my home network. Many of the tools I use for work are overkill for a "personal" datacenter. Except for some issues with the installer not doing the right thing (why I was up all night), it is great to have an off the shelf easy to install VM/cluster management system. Tom, wb6b

Re: Another battery question
Indeed, none of us have any argument with that.
Batteries concentrate lots of energy in a very small space,?that makes them dangerous.
Safest to buy a complete battery system and charger that is
well reviewed and shows few failures, and then thoroughly read the documentation.
The alternative is, as you suggest, to make sure you know what you are doing
before proceeding.?

Re: Navigating the FCC licensing system
Things changed here in the USA as of April 19 2022.
A new amateur radio license costs $35.
The 10 year renewal of an expiring amateur radio license also costs $35.

Re: Another battery question
Don, Years ago, I occasionally used a small inverter type DC arc welder to charge a 24v offgrid lead acid battery bank. Could set the current to something appropriate, this was way faster than any other charger I had available. Worked great for me but I don't recommend this technique to others, they might try using their AC buzzbox or not guess right on which clamp is positive.? If overcharged and/or poorly ventilated, the outgassing could have become quite dangerous. As Andy said:???"Without automation, we become the management system - the battery is as dangerous as we are."? ? Here's what Andy had to say about BMS's on RC aircraft batteries: "RC batteries aren't unsafe because they don't have an i ternal BMS. In RC use, management is split between the charger on the ground (charges, controls voltage and current, and balances). In the air, the speed controller monitors battery voltage and disconnects the load. The only weakness is cell level low voltage isn't monitored (though the low voltage disconnect is conservative for that reason)." So they keep the BMS as part of the charger, not part of the battery.? This reduces the weight of what goes up in the air, which seems ideal.? But anybody using one of those batteries (especially those charging at 25C!) should be using a BMS during charging.? The operator (or aircraft firmware) needs to be smart enough to land the thing safely before the battery expires.
Perhaps you object to this passage:
"My bench battery for the past 12 or so years was a 'naked' 4S 10 Ah LiFePO4 pack made from PSI cells. I didn't worry about low voltage monitoring because I seldom discharged to 50%. I connected to an analogue BMS when charging with my bench PSU."

Re: Another battery question
Never hand a hammer to someone that's never used one they will hurt
themselves, usually applied to many tools.
Technology masks the hazards but can and often do make us safer.
So to me the idea of low battery go home makes sense as it performs
battery protection and reduces other hazards.
Never said BMS/BMB were he only way just its common and most
cases its the way to do it.? As someone that flew electric models
and real aircraft sudden fan stops make for much sweat.

Navigating the FCC licensing system
Hello all. I decided to start this thread to tell you what I know about the current system used by the FCC for new licenses, renewals, upgrades and modifications. I am not a subject matter expert nor have I used the system to renew yet. I am a Volunteer Examiner and regularly see/hear the system explained to exam candidates and I also have helped my XYL navigate through the system for her license.? First, there are two parts to the system CORES and ULS. Simply, CORES is the part that takes your money, ULS is the part that handle the management of your license. Both are US Government web sites and do not have easy graphic user interfaces. To add to the complexity, there was an older version of CORES which became outdated on JULY 15 when the newer version came on line. As far as I can tell, information from the OLD system did not migrate to the new, hence the notices to go create a new user name and password prior this past July 15. If you did not do so, you will need to go to the NEW system and register plus create a user name and password. You can check availability for each on the web page for the new CORES. Here is the link for that: One MUST HAVE piece of information is a current, working e-mail address! Also, keep in mind info does not migrate from CORES to ULS so just because you have it in one does not mean it is in the other. Tracking?? Ok, if you have CORES registered and your user name/password work, then let's proceed to the ULS (Universal Licensing System). Here is the URL for the Universal Licensing System: Here are the instruction straight from the FCC page: Renew your license through the??(ULS) at any time within 90 days of the expiration date for the license and up to two years after the license expires.
To renew, go to the ULS Home, select Online Filing, and follow the instructions below.
- Login to the ULS License Manager with your FCC Registration Number (FRN).
- From your License At A Glance page, choose the Renew link in the right hand menu called Work on this License. When your license is within the renewal period of 90 days before the expiration date until the expiration date, or within the 2 year grace period allowed there after the Renew link will appear. If your license is not eligible for renewal the link will not appear.
- On the Select Updates page, review the licensee information displayed beneath the table of license information. If any of the data is missing or out of date you must update it. Click on the box to the left of the Licensee Information heading to insert a checkbox and select it.
- When ready click Continue.
- Answer the questions on the Applicant Questions page, and click Continue when ready.
- On the Licensee Information page, review and update all of your licensee information. Make any corrections that are necessary.
- On the Summary page review the information you have entered. If you wish to make additional changes, click the Edit button next to the section of your application you wish to Edit. You will be able to return to that page of the application. Make the desired change and select the Return to Summary button.
- When ready to submit your update to the Commission, choose the Continue to Certify button.
- After reading the certification, enter your first and last names in the boxes at the bottom of the page. You MUST sign the application. When finished choose the Submit Application button.
- From the ULS Confirmation screen, we recommend you print a copy of your application and/or the Confirmation screen itself from your web browser.
Note: The address and contact information you have entered in CORES registration will not be automatically associated with your licenses. To change the address or other contact information on your license, you must update your information in ULS.
(Joe again here): When your renewal is ready to be processed, you will receive an email containing a link for you to pay the $35 fee. DO NOT use a smart phone to pay the fee, use a regular laptop or PC. There have been reports of issues with people using smart phones to pay the fee, so avoid that.?
Ok, I hope this helps, I'm sorry if it's complex, but I didn't create it and don't necessarily endorse it, it just "is what it is!"?
To summarize, if you haven't registered in the NEW CORES system, you need to. If you are within 90 days of expiration, you can renew by registering in CORES and then going to the ULS and following the instructions above.?
Thanks and Good Luck!?
73,
Joe
