In Canada and the U.S. this is a long weekend (Labour Day Weekend) with Monday being a holiday. I was able to spend a little time on the radio in the late afternoon a few days of the long weekend. I was able to spend a few hours on both Saturday and Sunday. For the most part I spent my time on 20m CW and both days the bands seemed to not be too busy. As I spent some time on the radio I found the bands were not that quiet. It was deep QSB that was working its magic to drop an S9 signal just at or below the noise floor.
Having a radio with a waterfall is a great advantage and my Icom 7610's waterfall came in very handy showing me a signal before they would fade away to nothingness. I heard 4X6FR from Israel calling CQ and I was surprised he did not have a pile up. I gave him a few calls but he answered other stations. Not a problem I would just wait it out. This is where the QSB kicked in and within a very short time I found only static and no 4X6FR! The 7610 has 2 independent receivers which is a great advantage. In this case with my headphones I listened for a reappearance of 4X6FR in my left ear or VFO B. The right ear VFO A was scanning other signals that appeared on the waterfall. Needless to say, the station from Israel never again showed up on the waterfall, but he was still out there as he was being spotted by U.S. stations on DX Summit.
As time went on the best way to describe what I saw on the waterfall was "now you see them and now you don't" When I did tune on some DX and made contact it was touch and go to make a fast and simple RST exchange and if I felt lucky I added my name and location. I was pleased with my radio time and made contact with 4O4T in Montenegro, R5AF, SP6AEG, LZ305AI, IK5OPR and finally TZ4AM from Mali which was a new one for me. I saw him being spotted on 17meters and I decided to venture there as 20m was getting a bit slow.
The spot indicated "up 1" which meant there was a pile up and he was operating split. I skipped over to 17 meters and then landing myself on his calling frequency just to make sure I could hear him before I got too excited. There he was at S6 and I knew I had to move fast as the deep QSB had robbed me a few times from catching nice DX. I set my radio to split and dual watch which allows me to hear the DX and those who are calling him. BUT strange thing no one was calling him and my waterfall was void of signals. It could be the QSB playing games with me. So when I heard him call CQ I put my call out and he came back to me on my first call. TZ4AM was in the log and I was happy. Very shortly after the contact the deep QSB took the signal from the waterfall.
It's Monday today and I was busy getting some household chores done throughout the day. Maybe this evening I will be back on the radio and see how 40m treats me.
The 7610 has what is called "Dual watch" this utilizes the two completely independent receivers in the radio. This allowed me to leave VFO A (listening with my left ear) on a spotted frequency listening for a lull in the activity. VFO B (listening with my right ear) was moving around on the same band or different band hunting for a nonspotted colony station calling CQ. If VFO A was getting really crazy with callers but I wanted to stick it out for the just in case moment, I am able with a push of a button to mute VFO A. With each receiver you have filter, twin passband, NR, NB and antenna choices you can make to help out with you dealing with band conditions. Finally, as you can see from the screenshot above I was able to activate the "Dual scope" option and have a separate waterfall for 20m and 15m or you can do it for the same band as well. I have always been an Elecraft person (I still have the KX3 so I guess I still am) but I am very impressed with the 7610 a great bang for your buck!
At this point, I am looking for K2C out of RI and GB13COL in England and I want to continue using CW as all other stations were logged using this mode. At this point in time I have found that K2C spends little time on CW and as for GB13COL many have said they just cannot hear them and I concur. It 's getting down to crunch time as the 7th is the last day so let's see if the ham gods are smiling on me?

While on FT8 Saturday morning on 30m which is my normal watering hole these days with a cup of Java as I greet the morning I noticed a message appear on my PC screen. It was a message from my Win4icom software suite. Usually these messages are not a good sign and rarely contain info you really want to see while having fun on the radio. This message was not good news...and my FT8 stopped working, my rig was stuck in transmit and CAT communication was lost.
|Just love seeing these messages|

As for the contest I was running 60 watts (not sure of reason for the 60 watt number) and my antenna is the MFJ 1788 mag loop. I am in a condo so it’s a balcony antenna about 180 feet up facing south east. The software was N1MM+ and MRP40 CW decoder for the super fast fisted contesters. On Sunday the winds for some reason really picked up and my MFJ loop was moving around the balcony. I shut the radio down and took it in I would rather save the antenna from damage than taking a chance on getting more contacts.
I made only 25 contact and a score of 1575 BUT my intention was not to blow the doors off with a great score. Instead after I made contact with a station I would look them up on QRZ.COM and read about either the individual or the contest station. Over all the limited time I was in the contest I had a blast and was very please with the Icom 7610 and the ability of my balcony mounted Mag loop antenna.
