Greetings Diddlers:

Looks like most everyone took the evening off last week.  One new station, K3SSS, and his first time trying a RTTY contest.  Looks like Peter is using RHR, so I’m not sure which mult he was giving out.  Welcome Peter and hope to see you printing again.

Re: HAL - founder SK

HAL Communications Cofounder, President Bill Henry, K9GWT, SK
A cofounder and later president of HAL Communications, George W. “Bill” Henry, Jr., of Monticello, Illinois, died on July 17. An ARRL Life Member, he was 78. HAL Communications formally got its start in 1972 among hams and graduate students at the University of Illinois at Urbana, but the company’s history goes back a few years before.
Henry once explained that the name HAL was chosen by partner George Perrine, who picked the name because it was “one letter ahead of IBM.”
HAL Communications grew into a successful supplier of RTTY and digital communications modems, terminal units, and software, including CLOVER. Henry sold his stock in the enterprise to Barrett Communications in Australia in 2012, which continues to operate HAL Communications as a standalone business unit.

Greetings Diddlers:

Nothing like an upcoming RTTY test to bring everyone out of the woodwork.  16 stations reporting and a couple I know were on.  Quite the busy session.  Welcome to (relatively) newcomer NK5P who drops by on occasion.  There were lots of diddles on the bands last Thursday so I hope everyone got tuned up and ready for the NAQP.

microHam MKIII

Jim N7US
 

I previously used a MicroKeyer II with my K3.  When I replaced the K3 with a K3S, I replaced the MKII with a Winkeyer, two HB RTTY interfaces (from AA5AU's website), an N8LP SteppIR Tuning Unit, all of which I already had, and the soundcard CODEC in the K3S.  I had used the MKII to control my SteppIR but now use the SteppIR capability of PstRotatorAz.  My K3S has the K3DVR.

Now the MKIII is available with an improved soundcard, an analog-like RTTY tuning indicator, updated Winkeyer chip, and other improvements.

I operate CW, RTTY, FT8 (mostly on 6M), and SSB (mostly in contests).

I'd appreciate direct responses from anyone who is using the MKIII on their experiences, especially in comparison to the MKII.  Thanks very much.

K7A - Apollo 11 Anniversary in NAQP RTTY

With the anniversary this weekend we all will probably be copying some fun names in our exchanges. At least I do hope so.**

Please note however that LUNA is not a valid multiplier for North America. :-)

If you are a contester inclined to also seek special event stations, during the NAQP RTTY*** W7RN in Nevada will be operating K7A "Celebrating the Apollo 11 Moon landing from the Nevada Space Center". Special QSLs available by SASE, of course.

Yes there is really a Nevada Space Center, thanks for asking:

73 and have fun! jeff wk6i

Re: RTTY AFSK suggestions

Stick with MMTTY if you must but open a second digital window with 2Tone, set to 'spread'. You will often find that one decoder will print a clear callsign or exchange when the other shows garbage.
Here it's not FSK .. it's DOOK.

Subject: [RTTY] RTTY AFSK suggestions

Ever since I started using RTTY 5 years ago, I've used FSK. I've read many comments and suggestions about FSK vs. AFSK and I really don't want to re-hash that debate. But, I am thinking about switching to AFSK for the NAQP RTTY contest this weekend.

Note that I am not a serious contester. I like to participate and have some fun while I make contacts. Therefore, it's not unusual for me to make changes to my set up just before the contest starts.

I typically use N1MM+ for logging with MMTTY integrated into the logger for RTTY decode and encode. The radio this time around will be an Icom
IC-7610 with USB connection for CI-V and TX/RX audio.

So, knowing all of that, what suggestions do you all have for running AFSK? Should I stick with MMTTY or use something else? What MMTTY settings do you suggest? (Along those lines, if there's a web site or YouTube video that has already covered all this, please suggest some links.)

Thank you and I hope to work you in the contest!

Re: RTTY AFSK suggestions

I ran AFSK for years w/o issue---until I started running QRO for the W1AW Centennial...?? Too much trouble trying to filter the audio lines/pc/etc so just used MMTTY and Writelog to run FSK.?? Nearly all radios now have an easy way to key the FSK.?? Older analog rigs like my Drake 4 line were a bit more complicated but very doable.

At 100W I am sure no one even with a scope can tell you are using AFSK or FSK if the audio chain is working properly--as others have said, it can be mis-adjusted to provide real garbage.

Subject: [RTTY] RTTY AFSK suggestions

Ever since I started using RTTY 5 years ago, I've used FSK. I've read many comments and suggestions about FSK vs. AFSK and I really don't want to re-hash that debate. But, I am thinking about switching to AFSK for the NAQP RTTY contest this weekend.

Note that I am not a serious contester. I like to participate and have some fun while I make contacts. Therefore, it's not unusual for me to make changes to my set up just before the contest starts.

I typically use N1MM+ for logging with MMTTY integrated into the logger for RTTY decode and encode. The radio this time around will be an Icom IC-7610 with USB connection for CI-V and TX/RX audio.

So, knowing all of that, what suggestions do you all have for running AFSK? Should I stick with MMTTY or use something else? What MMTTY settings do you suggest? (Along those lines, if there's a web site or YouTube video that has already covered all this, please suggest some links.)

Thank you and I hope to work you in the contest!

Stick with the MMTTY engine in N1MM+. *HOWEVER* change the defaults in
MMTTY -> Setup -> TX -> TBPF/TxLPF to enable TX BPF with TAP=512 and
Freq=300. Also, keep your mic gain (or equivalent) down so there is
NO ALC.
