K9ZXO goes mobile! K9ZXO/M We've been operating mobile a lot lately. Here's how we pulled it off!
K9ZXO goes mobile. See the log hereK9ZXO tours W1AW In 2015, my wife and I toured the ARRL headquarters in Newington, CT and was afforded the opportunity of working as a guest operator of W1AW. It was very much fun. I was able to work 15 and 20 meters using Hellschreiber - a mode the Chief Operator admits isn't used there very often. Click the link below for a quick slide show: K9ZXO tours W1AW and the ARRL Two Strange Antennas One of my more recent projects was to construct a new antenna that would add a North-South pattern for my station.
It also would be capable of switching from a horizontal dipole to a vertical - changing the pattern and giving it some weather protection on call. The second antenna is one i use for Field Day and other special events. It is about the smallest footprint 20 meter dipole I've seen. The antenna is fan-folded, inductively tuned with a built-in balun.

APE AGAIN! - August PSK31 Expedition with the PODXS-070 Club.
To encourage PSK31 operations in the field and to research and gain practical experience in the portable capabilities of the PSK31 mode, the PODXS Ø7Ø Club offers to the members the August PSK31 Expedition (APE) Award. The APE Award is offered to any Ø7Ø Club member who during the month of August, organizes, sets up, and operates a portable PSK31 expedition which meets all Award requirements.
This year (as we did the last two years) my brother, Chuck (K9PLX) and I got together as a Special Event Station K9H to celebrate the 3rd annual excursion to our hometown of Jacksonville, Illinois - AND participate in the 070 APE event. See the published account of our 2011 APE event courtesy of the PODXS website and K9PLX. (Scroll down to K9PLX - K9ZXO ) See a short video of the 2010 APE here.

Digital Modes Demos and Identification
It is sometimes confusing for new digital hams to identify a particular digital signal by the sound of it or by what it looks like on the "waterfall" spectrum display.
Here are examples of the more popular modes. Click on the speaker to hear the signal (in MP3) or click on the waterfall to see what it looks like.
The Original Digital Signal - CW
BPSK-31 (Binary Phase Shift Keying - 31 Baud)
BPSK-63 (Binary Phase Shift Keying - 63 Baud)
BPSK-125 (Binary Phase Shift Keying - 125 Baud)
Domino-4 (4 tone)
Domino-8 (8 tone)
Domino-16 (16 tone)
FELD HELL (Field Hellscreiber
*Note: Hellscreiber is German for "Light Writer".
Also named for the inventer, Rudolph Hell.
FSK-HELL (Hellscreiber via Frequency Shift Keying)
MFSK-8 (Multi Frequency Shift Keying - 8 tones)
MFSK-16 (Multi Frequency Shift Keying - 16 tones)
JT-9 ** NEW MODE **
Olivia 125-4 (125 Baud, 4 tones)
Olivia 250-8 (250 Baud, 8 tones)
Olivia 500-16 (500 Baud, 16 tones)
Olivia 1000-32 (1000 Baud, 32 tones)

JT65A Users! New Software
Are you running JT65A? Are you using the WSJT7 software? Well, have I got a deal for you.
The software keeps a running log of absolutely EVERYTHING that happens. The logfile is called "ALL.TXT" and resides in the folder with the operating software (probably in your "Program Files"). While it is nice to have a detailed log to go back and refer to, it is so full of data that has nothing to do with your QSO that it makes it hard to find info about your contact.
I have written a small piece of code that will wander through your "ALL.TXT" file pulling out only the info pertaining to your call and writing it to a new text file called "jt65a_(your-call)_logfile.txt". That new file is written to the same directory. Now you have a detailed log of only your information - nothing else. Keep in mind that there are many repeated lines in the original file (I don't know why) so they will be repeated in the new file as well. But order out of disorder is always a good thing.
The file is an EXE. I make no guarantee about its accuracy or operation, but I've tested it on many platforms. If you note any bugs, let me know and I may get around to fixing them. Use it at your own risk.
