Re: Change request, add morse characters #firmware #qcx

While we're on the topic of prosigns, for a long time I thought BK was a proSign as a lot of people seem to run the two letters together and was -...-.- rather than -...  -.-  so maybe some were separating end-of-transmission as ...  -.- and some as ...-  .- instead of ...-.-  Jus' sayin...

In journalism, "no 30" meant “Filing not finished. More to come”.

And from arrl.org's Ham Radio History: Our familiar prosign SK also had its origin in landline Morse. In the Western Union company's "92 code" used even before the American Civil War, the number 30 meant "the end. No more." It also meant "good night." It so happens that in Landline Morse, 30 is sent didididahdit daaah, the zero being a long dash. Run the 30 together and it has the same sound as SK.

QCX Firmware change request: XON/XOFF flow control for CAT. #qcx #firmware #cat

Sheldon Hartling
 

Knowing the answer is probably "there's no room" :-) I'll ask anyways ...

Hans,

It'd be nice to have XON/XOFF implemented for the CAT serial port as an option to facilitate sharing of the IC2 pin 2 and 3 lines.  Currently, in V1.5, a CAT command received by the QCX during an LCD write is ignored.

 

Before driving IC2 pin 25 high at the start of an LCD write operation, you'd need to send an XOFF character (DC3, 0x13, ctrl-S) to the CAT port.  Then, when the LCD write operation was complete, after restoring IC2 pin 25 low, you'd need to send an XON character (DC1, 0x11, ctrl-Q) to the CAT port.  To be most effective, the XOFF would have to be sent as early as possible during the LCD write operation.  Unlike CTS it takes a little time to work effectively.  The XOFF character has to be sent over the serial line at 38400 baud, received by the computer, decoded, and acted on by the computer's driver software.

 

Not all computers/applications will support XON/XOFF so this would likely need to be included as a new menu item.

 

Thanks and 73, Sheldon VE1GPY

Yet another difference.  I was taught that <BT> was used for this, as kind of an "um, ah" thing.

<SK> stands for something (silent key/end of transmitting). Some key RR as E N  E N which makes no sense but has spread over time like the concept of VA instead of SK. Some key BK as a prosign.

Re: QCX Firmware change request: Validate CAT frequency values. #qcx #firmware #cat

Sheldon:

I think Hans is down to less than 10 bytes of unused memory. Another problem is that "out of band" likely varies at different places in the world. I'm not sure if Hans could use the EEPROM space, but that still means a change in the source code, and that's not going to happen.

Hi Hans,

 

Please consider validating the frequency values received in "FA" and "FB" CAT commands to confirm they are valid for the QCX's band.  Currently, in v1.5, out-of-band values are accepted and set the VFO to unsupported frequencies.  Easy to do, by accident, when hand-entering values in logging programs.

Not sure there is sufficient program space go support this and it varies by location.
For sure about sufficient space!  I've developed firmware and am painfully award of the challenges trying to "shoe horn" additional features into very limited space. 

Even a range check that looks for reasonable (course) values for the band without following the specific regional band plan would be a help.  Right now, I threw my QCX into a sputtering fit by entering "70201" instead of "7020" in N1MM+. ☺︎

Re: Adapt A Bioenno 24v LiFePO4 Battery To Run The QRPLabs 50 Watt PA?

Allison,

I thought it was Megawave, but didn't think I had the name right! I used to interface with Marshall! He spoke very highly of you, as I recall. I really enjoyed our interactions! 
Are you still with Megawave?

I saw on your QRZ page that you have what I remember as a 'Squalo'- 6m square loop. I had a ham loan me one of those antennas for a field day here in Arizona back 32 years ago. I had the Yaesu portable 6m radio with self-contained battery pack, and to my amazement, I talked with a guy in Hawaii that day!

What has your experience been with your ’Squalo'?

Great to chat with you!

I'm assuming the QCX knows which band it was built for; based on the stored answer to the "Select band:" question answered during initial setup.

The Harbor Freight Apache cases are watertight and pretty inexpensive when they're on sale ($10). However, they are very rugged, so they weigh a little more than you might want. Next time you're at HF, check them out. There are 3 sizes (I think)
I use these for my Celestron 6" telescope and when flying with the FT891.  GREAT cases for the money but a bit too heavy for SOTA operations.  :(

This may require a different firmware for each band.

Dollar stores have a selection of thin plastic boxes for

For just waterproofing one could probably use zip-lock style baggies.

<SK> makes sense to me.  I've always thought of it as "Stop Keying".  Similarly, I think of <KN> as "Key Now".  Not sure what to think of VA. :-)

When doing yachtmasters in 76 weather reports were in morse and VA was used. Sarasota Florida, club which helped me study for my US licence VA was used.
UK licence course in about 84 used set book "Amateur Radio" by Robert L. Sharader W6BNB (Former chairman of Electronics Laney College) US publication, used both VA and SK. (pg296).
SK always suggests someone has died to me and gives me the shivers. Please lets use VA.
