Shane,

Retired two years ago.  Marshall is local to me and still on the air W1HK.
Had a lot of good fun and worked on a lot of interesting projects like
the body loaded antennas.  Did a lot of field testing, antenna evaluation,
and prototype development.

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

That's still not cut-and-dried if out-of-band can vary among countries. The only alternative would be for Hans to offer specific 328 chips for each country for each band. That's a train just begging to leave the rails. I say this because, last I talked with Hans, he was down to less than 10 bytes of free memory.

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+. ☺︎

Using either can result in confusion for non-professional CW ops.
An extra  microsecond or two  to confirm end-of-message would facilitate clarity,
especially for those of us who are sub-perfect and hope for
inclusion and encouragement.

Anyway the real issue is not whether it is SK or VA (or EEETET), but whether they have a bar over the letters to signify that they are sent as one character. I don't know that there is any easy way to do that with the 1602 character display. Even if there is a way to define a new character, that would probably take up a significant amount of memory on the '328P chip, of which I hear is in short supply.

Sheldon   Most of us here in the states have no idea what to think about the VA, either! (Veterans Administration) Thanks to all, this thread has been most entertaining. I would strongly suggest that you ask one of the teachers in the LI CW Club. FYI, there is a whole new/older group of us that read it as "SK".

But just remember the FCC saw fit to give me the call  "AG5SK", you think they were trying to tell me something??

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...

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.

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.

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!

73,
Shane

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.
