My first contact as VE9KK
Well once the headphones were repaired and I ran through the starting of the radio software and making sure it was speaking politely to the radio I was off to try my hand at FT8. I was calling CQ on 20m and on Hamspots my call was being spotted in Europe and I was thrilled! Back at my condo QTH in Toronto I was only spotted in the U.S. and there was a spot in Iceland as well. It was not long at all until IU8DON from Italy answered my CQ call on FT8!! I was amazed that my signal was making it finally across the ocean. I did not have to much time after the sorting of the software and radio communication testing but the contact with Italy just made my day!

Well it’s now official!
It's now official on paper with my new call sign for New Brunswick. Funny thing the other evening I was calling CQ (CW) and a few times I used my old call without evening noticing it. Old habits die hard I guess.....it's just going to take time to get the new call rolling off the key like the old one did.
Some positive steps forward with shack RFI
| Old HDMI monitor cable |
I am the kind of person that things just don't click right away and I need time to mull things over. One thing that came to mind was my monitor issue I was having. I was using an HDMI feed from my PC to the monitor as I always have in the past BUT in the past I was not faced with the RFI issue. Chameleon Loop antenna and I remembered the coax that came with the antenna had a set of RF
| Chameleon coax choke |
I replaced the HDMI cable with a DVI cable that had RF chokes at either end. This solved my monitor issues of it waking up from sleep mode on it's own and characters showing up on the screen.
I did on Friday end up ordering the Balun Designs 1115 Balun and it should be arriving within the next week or so. My positive tests using the RF choked coax tells me that the purchase of the Balun was a good choice. My next step will be to try out a counterpoise that is 25 feet long secured at the PL-259 that feeds the W1SFR Endfed antenna and see what this step produces. I am hoping with the new Balun, the counterpoise and changing the monitor cable will solve the issues I have been experiencing.
It now the next day and my experiment with the separated 25 foot counterpoise have been completed. I stripped one end of the 25 foot piece of wire and attached it to the outside of the PL-259 using a screw clamp similar to the clamps you see on automative rad hoses.....but much smaller. I checked the SWR on 40m, 30m, 20m and 18m and it really did not change much but what did change was the amount of RFI what was showing up on my waterfall on the 7610. I then removed the counterpoise and the offending RFI was gone. So that was good enough for me I am going to keep the Chameleon coax with the chokes in place until the Balun from Balun designs comes in.
The Endfed antenna is up but with mixed results.
The W1SFR Endfed antenna is up and things went very straight forward with the install. My options for a location a limited so I ended up having to place the antenna in a tree that beside our mini home and then down to the shed about 40 feet or so away. The antenna runs parallel with the mini home along the north side of the mini home. The feed end of the of the antenna is about 25 feet up and mounted to the tree. The far end at the shed the antenna is about 15 feet from the ground. The coax from the antenna to the shack is about 65 feet in total as the Endfed antenna uses the coax as the counterpoise and Steve W1SRF recommends you have at least 25 feet of coax. The time came to flip the switch on my antenna analyzer and see some SWR results:
Band. Freq. SWR
40. 7.0001. 1.9
40. 7.070 2.5
30. 10.100. 4.4
30. 10.150. 4.5
20. 14.001. 4.5
20. 14.070. 4.3
17. 18.068. 1.5
17. 18.168 1.5
21. 21.001. 1.8
21. 21.070. 1.8
I was a bit alarmed by the results so I emailed Steve W1SFR regarding the results from his Endfed antenna. He came back with positive comments saying my results looked very normal. This is the very reason it's said that with the Endfed antennas you need to use a tuner. The next step was to connect the Icom 7610 to the whole mix and see how things worked. This is where Murphy popped his head up to give me grief! I began to transmit on 40 meters and with the power at 40 watts things started to happen around the shack and house! In the shack my PC was not running but the monitor was in sleep mode. All of a sudden the monitor would wakeup from it's sleep, on my PC desktop I have a program that allows me to post notes on the desktop when I transmitted CW I would see random letters being typed on a posted notes on the desktop, my electronic keyer would send dah's and no dits and finally our new electronic washing machine would just shut down. The other band I tried was 20m and when transmitting CW at about 60 watts the PC monitor would wake up from it's sleep but no other issues. I was wondering it it was the RF coming back on the coax or because the Endfed run parallel with the mini home is about 15 feet away from the home?
I contacted Steve again who informed me that it could be RF on the coax as it's a counterpoise. His suggestion was for me to purchase a 1:1 balun and from there see if it solves the issues. Steve suggested it may or may not solve all the issues and I may have to look at other options for unsolved issues. Well I have a decision to make....do I want to start spending more money and go down a road that may lead me to gaining more "stuff" but still not being able to use the antenna. Now I did get some comments from my blog readers who do have and are using with success an Endfed antenna.

Ever so slowly things are coming together.

Antenna planning for the fall and winter.
I'm looking at (in my spare time) an antenna I can use over the winter months and then when the spring comes and more time on my hands to then further explore antenna options at the new QTH. At this time I have two options......the first is to setup the MFJ 1788 mag loop in a wooden shed that is at the back of the property. For this option I would have to first see how the loop and wood shed react with each other. If there is no issue this may be a good option for the winter as the antenna is protected from the elements. The other option is an antenna I have had in the drawer and really have not used, it's the W1SFR Endfed 6m-40m antenna. With this antenna I can secure it to a tree at one end of the property were it would be about 30 feet off the ground. Then terminate it out by the shed were it would be about 10 feet off the ground. The Endfed antenna is 35 feet long and is not a problem fitting on the property. With the antenna being secured to a tree at one end I have to take into consideration the swaying of the tree in a wind. I was going to put an eye hook into the tree and then a short spring and then attach it to the Endfed housing this I am hoping will allow some flexing via the spring if a wind picks up and the tree starts to sway. The W1SFRR housing is not meant to be premaritally outdoors as the case is not water proof but water resistant. I plan to wrap the housing in self amalgamating tape which would no problem keep the water issue at bay. The advantage to this antenna is I don't have to keep retuning it like I do with the MFJ Mag loop. Once my Icom antenna tuner programs into it's memory the tuning of the Endfed I hope I can just tune across the band and not worry about tuning as I do with the MFJ loop.
Any input from fellow hams who have faced such an adventure would be great.
