Re: external straight key

Chris Morrison
 

Hallo Willi,

Thanks for the info on the straight key, it’s now working well!
Have enjoyed getting started with the echo trainer for several hours but now my LiPo battery seems to be dead!
I connected the USB charging cable to the Morserino and to a regular 5v Phone Charger - a red LED lights up but not sure when the charging is completed, does this LED go out or change to white?
Also not quite sure of role of red button in turning device on and off. Should I set the ’sleep’ option as a default or always use the slider switch?

Sorry for all these dumb beginner’s questions

Thanks,
Chris

P.S. Have sent out cq on LoRa but not sure what to expect here. Should I see a reply on my Morserino if there is somebody nearby? I listened on 434.15 MHz on my Yaesu FT 897, sure enough I can here a brief noise there when I stop keying!! Look forward to your promised instructions on this when you publish them, keine Eile!!

Hi!

A straight key can only be used in CW Decoder Mode right now!

Re LoRa: It is set to 434.15 MHz, and uses a bandwidth of 250 kHz. Transmissions are very short bursts (always sent at the end of a word) spreading across the bandwidth, so hard to detect with a normal receiver.
When I find the time I will publish the protocol that I use for encoding morse code on the GitHub site.

Thanks a lot Wolf,

I did all this but the straight key somehow activates the iambic keyer circuit producing a continuous series of beeps. Of course, with the straight key, I have only 2 connections, tip and ground.

I have a second unrelated question about the LoRa unit, with which I’m totally unfamiliar (!!) What frequency in the 433 MHz region does it send on and where can I ‘hear’ if anybody else is around. Sorry if this is a very naive question.

Best regards,

Dear Willi,
can you already predict, when you will release an update for the m32-firmware?
Especially the issue with the "dit"-timing is quite annoying.

Wolf, OE7FTJ
 

Chris,

the port to connect your straight key is the same as for your external paddels - it's the 3,5mm socket on the frontside.
But change the top level menue to 'CW Decoder' and it works.

Hi Jörg,

I'm posting here because I am new to the blog site and I don't see how to start a new question, sorry!
I have the same problem as you - I would like to use a straight key but only have the 2 paddle choices you mention. According to the instructions, it should be possible to use a straight key but whenever I connect it, the iambic Keyer is activated and I just get a series of beeps. Even in the CW decoder menu it doesn't work. Maybe Willi has a suggestion for how to actually connect a straight key??

Hi Chris, 
It turns out that the Tattu batteries they sell in the US are too wide to fit under the processor. Both Tattu models are 600ma so it is confusing. The thinner one is 30C discharge rating, not 25C. 

Another forum member recommended this battery and it fits great under the circuit board. The USB charger is excellent too.

Hi Chris,
I just finished building my Morserino.
Using a Tattu 600 mA H as recommended. It protrudes inwards from under the LoRa unit but that‘s not a problem at all. Works a treat!

v5.2 Tester?

Servus,

hier SRG, mittlerweile DM4SG.

ich hab in letzter Zeit immer wieder an der firmware vom alten
Modell mit Arduino weitergeschrieben. Es ist noch nicht so reif, dass
man es in die dropbox legen könnte, aber vielleicht mag der ein oder
andere dem mal einen Test geben? (siehe zip Anhang)

-> neuer Generator EIGENE, der einen zuerst nach den Zeichen fragt,
die man in 5ergruppen üben möchte.
-> neuer Generator QSO, der aus der Liste der abbrevs und den weitern
generatoren versucht, halbwegs sinnvolle und halbwegs vorbildlichen
QSO text zu generieren. (weil ich persönlich qsotext irgendwie immer am
schwierigsten finde, wenn wir hier im OV üben).
Die Datenstruktur qsotree dafür wird von einem pythonskript
generate_qsotree.py erzeugt. Hoffe, das ist verständlich.

Damit die zwei möglich sind musste der ganze Generatormechanismus auf
Wort-für-Wort statt Zeichen-für-Zeichen umgeschrieben werden, das macht
die Statemachine jetzt viel einfacher, finde ich.

außerdem:
-> verbessertes Copy Game, das jetzt Leerzeichen komplett ignoriert
und dafür im Sinne des qrq automatisch an der Geschwindigkeit dreht.
-> massiv mehr benutzung von CPP macros, damit man die hartkodierten
Zahlen möglichst nur einmal irgendwo hat.

fehlt noch: Semikolon und Ausrufezeichen ordentlich behandeln. Handbuch
update. Brandneue bugs fixen...(z.B. wird die Zeile "(qru wid <ka>)"
nicht immer gezeigt...)


Ich werd das Ding in der Form jetzt mal einige Wochen liegen
lassen und erst frühestens im März wieder was dran machen.

Es wäre toll, wenn der/die ein oder andere YL/OM Lust
hätte mal ein paar mal den qsotext generator laufen zu lassen und
drüberzuschaun. Mir fehlt da z.B. doch die Sicherheit, wo die
ganzen Opcodes wirklich angebracht sind etc. . Deutsch/Englisch bzw.
OM/YL ist der Einfachheit halber nicht konsistent bisher, ich weiß
nicht, ob sich der Aufwand dafür lohnen würde.
Und immer gern her mit Ideen, was der qsotext Generator sagen könnte, es
sind noch ein paar bytes frei im ROM :) und viele abbrevs
unbenutzt oder frei, bzw es gibt noch ein paar, die man ohne großen
Verlust austauschen könnte. Wenn zum Beispiel jemand Lust hätte, einen
Baum für ein contest qso zu machen, pse k.


mni tnx es 73 de dm4sg, Stefan


PS: hat es sonst noch bei irgendwem PIN9 zerstört mit der Zeit (->

Re: Battery charging

Very strange behavior. I am not sure what’s going in there, and how (or if) I can do anything via Software to improve the situation. Charging itself cannot be influenced by software, but measuring the voltage is a software feature, but apparently a very unreliable one. I will do further experiments (documentation is hardly available), and if I find something useful, will incorporate it into the next firmware release…

I am not sure at all if these batteries have an internal charger or not. I will try and get hold of the exact model you have recommended. I can not find it in Ireland unless I buy 6 at the same time for about the price of the morserino. It may take me a while to get one but I will report back when I do. Thanks for the advice.

Are you sure your battery is just a single LiPo cell without any electronics like charging regulator in it? A battery with built-in charging electronics probably cannot be charged through the Heltec module, as it requires much higher voltage levels than the Heltec module would provide.

Bug: Tone Shift in Echo Mode does not work

Willi, OE1WKL
 

AS DK4RW rightly pointed out to me, there is currently a bug in Version 1.0: no matter how you set the parameter for Echo Tone Shift, the resulting tone is not changed. I have identified the issue and it will be resolved in the next firmware release!

I have had to charge externally for best results. Wake up screen will then show 50% battery and I get a lot of operating time. Perhaps this is due to the charging protection in the battery? 

I'm glad I listened to Gary W4EEI and purchased these batteries

They come with a nice USB charger with accurate charging light. Plus, I have a spare battery for the future.

Update: I left the unit on to discharge the battery and at about 3.1V the microprocessor gives up. . I plugged in the adapter and it started charging (orange light was on). Charging current was about 70mA. After an hour the voltage had climbed to 3.44V but the charging current had decreased to a few milliamps. At 3.54V charging current was a fraction of a milliamp although I don't think my ammeter is all that accurate. Over the next few 4 hours it climbed to 3.67V. On waking the unit the battery symbol was all but empty. So basically it will only start charging if the battery is very low and stops charging at just over 3.5V. No load charging voltage is 3.74V (battery disconnected). So charging does work but is all but unusable.

Best regards
Tim

Great job with the kit, it was easy to put together and worked immediately.

However I am having a problem with the battery charging. I am using a 1000mAh 3.7V battery which appears to register as empty when it gets to approximately 3.55V . When running it shows 70 to 80 mA discharge and when asleep about 15mA. Plugging is a 5V 2.1A adapter when in the off position will light the orange light. Switching over to the on position the light goes out and there is no discharge from the battery. When it goes to sleep there is no current to or from the battery. If I plug the adapter in when asleep the 15mA drops to zero. It does same on the two identical batteries that I have. They both charge normally using an external charger. What is really confusing is that the voltage at the battery goes from 3.5v or so to 4V but there is no current to the battery and the light is not on.

Bit of a pain but just a minor inconvenience as I can charge externally and I do have two batteries.

Thanks, Jamie, for the suggestions.

I couldn’t find the remark about black solder mask on the eevblog - what is wrong with it?

Sorry for the other inconveniences with the PCB - this was pretty much my first PCB design (the first real one, produced in more than 5 samples) , and I certainly can still learn a lot in this area!
