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!!!

HRD DM-780

Another day in the shack but not really on the radio as so much as setting up the radio. I decided to take the plunge and go head first into setting up a digi mode. PSK was my weapon of choice. I did some looking over of notes last night to get my mind into it. The software I have preloaded on the PC is  Julian's Kcomm, fldigi and HRD's  DM-780.  One of the trying tests for me is to get the radio to communicate with the
software. I was not disappointed.... figuring out the com port, stop bits, CAT settings,

Kcomm with fldigi

handshake or not....and the list goes on was a challenge. Then there is the sound card setup and settings!! Some of the troubles I ran into were.....not being able to get the K3 to key up when the software said it should. After overcoming that  the K3 had no problem keying up but then would not un-key at the end of the macro!!! After solving those two hurdles I then had troubles getting the 5 watts output I wanted to have. It turned out to be a jungle of sound card tuning and radio tweaking. I was not sure how I did it but I am now able to have a solid 5 watts out on all bands and simply adjust the K3's power control if I want to increase the power. I won't try to figure out what I did as when I do for some reason I un-configure  the configured. The software I decided to stick with was DM-780. Kcomm is great and works well with the

K3 radio. The setup of communication between the radio and software was the easiest of all the software I dealt with. I was not able to get the waterfall going I did integrate fldigi waterfall but it seemed to run as two separate programs. I was getting frustrated at this point and really never looked into getting around this issue. One great feature of Kcomm are the macro's that control aspects of the K3.  With running fldigi on it's own I was not able to get the K3 out of transmit when the macro was done sending....again frustration was setting in. I am sticking with DM-780 but have to do some reading on how to customize the macros and some other minor settings.

CT1IUA on the beach

Good afternoon fellow bloggers, went to see the Chiropractor and Physiotherapist today regarding my back troubles. The news was...... come back and see us and in the mean time REST!!! Well for me it is very hard to sit still and Julie can attest to that. One way to make sure I sit still and rest is to softly hobble into the radio room. I started out the day on WSPR I was transmitting 1 watt on 20 meters. The big reception report for me was from FR5DN on Reunion Island. At 1 watt that made it 9463 miles per watt for my attic dipole. I also tried some CW on 30m and 17m. Now my DX-33 dipole is not resonant for either of these bands but the K3 does

have a tuner so I gave it a shot. Things did not work out very well although the bands seem to be open my signal was just not happening. The LP-100A meter here was showing an SWR up to the antenna of 8.89:1 on 30m's and 9.3:1 on 17m's. The K3's tuner was able to bring it down to 1:1 so the K3 was happy. Later in the day it was off to CW and I checked DX summit's cluster and found a spot for CT1IUA in Portugal. I spun the K3 over to the spot and there was a nice pileup trying to make contact. I gave it a go and was able to snag CT1IUA on my first call with 5 watts. I then saw a spot for PV8ADI in Brazil I spun the dial in that direction and there was not really anyone calling him. He in fact called CQ several times without an answer. I gave him a go at 1 watt but that did not seem to do the trick. I then went to 2 watts and he was able to make out my call with 2 repeats. Funny though I still got a 599 as a report. So at 2 watts that makes it 1529 miles per watt on that contact. I did notice there was lots of action on PSK on the cluster so this evening I hope to get PSK all straightened out this evening with my rig and the software. That way on Tuesday I can maybe do some digi contacts.

Today while putting some laundry way in the bedroom I threw my back out. I  simply hung up a T-shirt in the closet and that was it. I was on my knees and down for the count, this has happened in the past and I do see a Chiropractor one a month for up keep.  Now it will be off to the Chiropractor to slowly get better. I will be off work but at this point not sure for how long. I do know there will be no lifting, house work or sudden anything with movements. Hmmm radio does not require any of that!!! So it looks like here at VE3WDM part of the healing will be radio and rest....:)

This was a very cool contest only lasting 3 hours on a Saturday morning giving me with some nice radio time and time to get other things done as well. The QRP ARCI Pet rock contest (please if you know why it's called the Pet Rock contest let me know) is a great way to make some nice QRP contacts. One thing I did find is you sure do put the rig's filters through the paces as you try to copy some signals that are very close to the noise floor. I was not in this one to win it or even come close but to log some contacts and look them up on QRZ.COM to learn about who I just contacted. The contest started at 10 a.m. local time, there was nothing on
10m, 15m gave forth some contacts but the best band was 20m. In this contest it was nice  leisurely  CW not like the world wide contests were CW sounds more like machine gun fire! Also during the occasional contact more was given than the required exchange info.....SAY IT AIN'T SO........we tossed around our names, rig and at times a hearty 72. ( that was not a typo 72 is the 73 of QRPers) This was the first time the Elecraft P3 was used in a contest and it was a great aid. It would show you what looked like just the noise floor but in the water fall below on the display a signal is made very apparent. Then along with the K3's APF (audio peak filtering) the signal just jumped out and a contact was made. This really was the first time I was able to see how great the APF was on the K3 I had tried it in the past and to be honest was not impressed but that has changed.
Power output          5 watts ( I can say I operated QRO compared to others)
Total contacts          9
Total points             2352
It's no record breaking contact count but this short contest was a blast there were some contacts I just could not put in the log as I did not get the full exchange due to fading. Also at times I got so excited about making a contact it wasn't until the contact was complete and it was ready to be entered into N1MM that I realized it was a Dupe!!! But not once did I get the CW sent to me B4...sorry for not paying closer attention gents and ladies regarding this but thanks for your understand.

VE1BA's shack

Well on Tuesday it's back to work and one of my 2012 ambitions....don't like the word resolution with me it is linked to a list of "non-goals". So for 2012 the buzz word is "ambitions". Well as I was saying the new ambition is to get on the rig more. This afternoon I did just that and had some two way QRP contacts. The first was with John VE1BA down in Nova Scotia. He was running 2 watts into an FT-817. At the time I thought I was running 500mW's but the K3 was set at 5 watts. So that gave me only 153 miles per watt. We had a short but nice chat on 20 meters. I had a chance on the K3 to use the APF filtering as John's RST was 229. The APF worked great as he jumped out from the noise floor.

I then called CQ on 14.060 and Mike N0ZH came back to me with a 559 signal. He gave the the same signal report. It was not long before Mike started to fade in and out and very hard to read. So my QSO to Missouri came to a fast end. For this QSO the K3 was at 1 watt with a better miles per watt at 694 miles. I did hear KF5HGL calling CQ I started returning his CQ at 500mW's and climbed all the way up to 5 watts and he was not able to copying me. So either conditions were changing or it was not time for me to make a QSO into New Mexico.

N0ZH's shack

So how was 2011 here at VE3WDM,

I have always been a QRP operator but for the first time I decided to drop my output power to less than 5 watts. By the end of 2011 the output had dropped to 500mW's or less with great success as well.

I took some time to look around the shack to notice how much "stuff" I had that was just taking up space. I then put up for sale items I was not using and made enough for some new toys.

I discovered WSPR and all that you can do with it. 


 I was able to upgrade the shack. The Elecraft K3 was upgraded with a second receiver and matching filters. Along with some added treats.

My main contest antenna was the Sidekick from High Sierra antennas. It was a great antenna that gave me coverage from 10m to 80m. The problem was it could only be outdoors when I was on the radio due to antenna restrictions. I tried the Sidekick in the attic along with my 20m dipole but it just did not work.

I sold the Sidekick and ordered the Alpha Delta DX-33 and installed it in the attic. I am now able to work 10m to 40m anytime I want and not worry about an outdoor antenna.

I found time to get some kits done and added to the shack. 

I also had some Plasma TV interference so I purchased an  MFJ-1026 and that fixed the problem it's a great unit.

I did more portable op's this year with my Elecraft KX1 and had a great time.

There was my trip of a life time to the UK and ham radio came along for the ride as well. 

There was some wall paper added  WAS awards, 1,000 miles per watt at 8,325 miles per watt. I then topped that record with 16,737 miles per watt.

Much more went on but these were the highlights here at VE3WDM!
