1st PSK QSO with K5ZG

I want to thank all those who posted comments and emailed me direct to help my PSK journey along the road to success. Today I sat down and read all the comments and considered the feedback which helped me  get a plan going so I could be on the air with PSK. So what was wrong....well the good old Elecraft K3 was for some reason not set up the way I thought it was. I went back into the manual to see what the recommended settings were. The K3 when in DATA A mode (which is the mode that is recommended for PSK) the Line out to the Tigertronics Signalink is not taken from the MIC but the rear LINE OUT on the K3. That was the first problem it was not. I am sure I selected LINE OUT rear panel....but the menu does not lie!!! it was set to

fldigi and KI4BIY

something else. So that was changed and I gave some PSKing a go.... but still nothing!!! So it was back to the K3 settings again, this time I had to check to make sure DATA A was set to DATA A.  I thought it had to be as  the LED readout on the K3 reads "DATA A". I checked and DATA A was set to PSK D what ever that is  so I set DATA A to DATA A. It was then that things seemed to be looking up. I saw a station (K5ZG) calling CQ on the waterfall, I gave him a call and he came back to me!!! SUCCESS I made my first QSO on PSk but the QSO was not complete as QRM and the band conditions were changing and he faded away before the QSO was completed. I then closed down DM780 and opened up Fldigi to see how that worked. It was about 20 min's or so later I made contact

with KI4BIY. The problem here was not the band conditions or the contact but I was using Fldigi and had NO macros setup. So it was live PSKing but I  was able to have a very nice QSO. This gave me the confidence the program was now working. There is one question I still have, when I transmit my output power can start off at 5 watts but as the transmission progress the output can climb as high as 12 watts before leveling out. I can readjust the output and get it to stay at a steady 5 watts but it takes some adjusting and readjusting of the Signalink TX. Any thoughts on this.....is it normal or are there more adjustments to be made??

Through Eldon, WA0UWH I have discovered another blog to add to the blogroll: that of Jeff, KO7M. Jeff is interested in a lot of the same things I have been (including light aviation: an ambition of mine when I was in my 20s but which I could never afford to take up.) But what really piqued my interest was that he has just got a Parallax Propeller to generate a WSPR signal.

This is one of the things I was interested in trying. But I never got further than wondering how to implement the fractional frequency shifts of the WSPR signal, which uses 4 tones shifted by just under 1.5Hz from each other. Jeff has apparently found that a 2Hz shift is good enough to be decoded, allowing WSPR to be sent using the integer frequencies the Propeller chip can easily generate.

Once I have finished the Tiny Keyer project and can get back to the Propeller I will be trying this myself. My ambition at the moment is to make a multi-band multi-mode (OPERA, WSPR and perhaps QRSS as well) standalone beacon with an LCD panel to enable me to choose the band and mode. We’ll see how far I get, but having two other people working on the same ideas should certainly make the task easier!

Giving PSK a go

On Wednesday I spent some time familiarizing myself with HRD's DM-780 and getting some custom macros setup. In time I am  going to try out Fldigi and see which program I like better. The only reason I started with DM-780 was the K3 is all setup with HRD so I am half way there when it comes to PSK. So how did it go...well I am operating at 5 watts and there were some stations calling CQ but I was not able to grab their attention with my replies. I setup DM-780 to send info up too PSKreporter but up to this point and including today I just don't seem to be spotted at all. I am not sure if my setup with PSKreporter is wrong or I my signal

Action on the band

is not getting out. I do see on my LP-100 watt meter there is 5 watts getting to the antenna but whether it is readable or not I am not sure. Besides I am still getting the hang of PSKreporter as well so it could be operator error at this end. Also today I was involved in the NAQP CW contest but am now just taking a bit of a break. I was calling CQ on 40m CW a short time ago and KC9SNC came back to me. Our QSO was going well and the CW speed was very comfortable for me.......then came the contester's right over our QSO!!! Now they may not have heard us as I was QRP at 5 watts but that brought the QSO to an end. I did email Matt and gave him some more info about my station and that we may have better luck next time. So up to this point I have not been able to make a PSK contact maybe I will give Fldigi a go on Sunday and see if I can bag my first PSK QSO. It's now time to head back to the NAQP CW contest......and try not to QRM anyone who is not involved in the contest!!!

There re just a ton of data modes you can play with and this morning was the turn of JT65-HF to be on my screen. I’d installed it quite a while ago and not used it for some months but I thought I could do with giving it a quick run through to remind myself of the protocols in case we use it on the SOS radio week operations (as GB4LBC for St Bees lifeboat station).

Time is very important with JT65 and a few other modes and I’ve never been a big fan of windows time setting utility. It never seems to be right and there is always a problem with either this or that. I use Dimension 4 on XP machines and it works very well. Under Windows 7 you have to remember to run it as an administrator so I suspect the same will be true for Vista. there seemed to be a bit of a conflict going on on my puny little computer so I had to reinstall JT65-HF and only then did it start to decode the received signals.

I took the opportunity to use my stealth antenna (A Watson 80 plus 2 dipole – which is really only good for 20m here) and immediately got a contact with DG8RW & W3PV with 15 watts. I had a bit of trouble with the first contact as he couldn’t copy my signal report for a while and I had to resend it quite a few times before he got it. Eventually we got a QSO together and that was pretty pleasing.

So I’ve got my hands dirty again with JT65 and whilst its not the most interactive of modes it reinforces the fact that SSB is inefficient in comparison as I doubt I’d have got where I did with 15 watts and a loft mounted antenna. Still, it was a nice distraction from what I should have been doing. That was to be revising for an exam on Tuesday. Nothing exciting, a professional exam and much less enjoyable that playing with radios.

I’ve setup an independent blog site to somewhat showcase my past and future SOTA or Summits On The Air activities.  In addition to posting alerts to future SOTA activations and detailed trip reports after, I also plan to post some “How To” or instructional related topics all about SOTA.

These special instructional SOTA topics can all be found under the category of “How To”.  In addition, I’ve setup links to all the various SOTA related websites and even documented some of the gear I carry along with me.  The gear page explains what I use and also details into why and how. 

You can access The SOTA Activities of KD0BIK by clicking the SOTA Activities link at the top of the page. 

Thank you to all who continue to read my blog sites and listen to the podcast. 

Until next time…
