Alpha Delta DX-EE

 Many Amateur radio ops now find themselves in a neighbourhood, downsizing to a condo or moving to an assisted living complex that is ham radio antenna unfriendly. I have lived in many antenna challenged, HOA and condo rules that outlaw antennas. But I have always managed to get on the air using HF and enjoy the hobby. Over the next few posts, I am going to share how I accepted the antenna challenge and kept the HOA hounds or condo cops from having their heads spin backwards. Today let's look at a situation that involves home HOA hounds or townhouse condo cops. 

In the neighbourhoods I have moved to I always get a copy of the rules. (HOAs and condos have more pleasant words than rules) But let me start by saying I am not against having common understandings (rules) as it can control some funny things that can pop up in uncontrolled neighbourhoods or condos. In most of the rules I have read regarding antennas, it boils down to you can't have them due to safety, how they look and the size. The way I see it is if it's safe, no one see's it and it's small then we are good to go with an antenna! 

The first big hurdle is out of sight, as with amateur radio an HF antenna can be a tough one. For 16 years I lived in a townhouse which was not antenna friendly. I found we had a very large attic and then the next challenge was what to put up there for HF operations. What I tried was 2 mobile whips configured into a dipole. This had a very narrow bandwidth and only a single band as I could not set up more than one due to space and interaction. A band change meant getting up in the attic and doing the whip change. That idea was deleted due to attic heat in the summer and just getting up and down from the attic. 

Electric fence stand-offs

My goal was a multiband antenna that was small and could be left in the attic and forgot about. I committed to a dipole antenna from Alpha Delta the DX-EE model. This was a 10-40m antenna that was 40 feet long. Now my attic is nowhere close to being 40 feet long but I ended up installing it in a "Z" configuration. To secure the antenna in the "Z" configuration I used electric fence standoffs. Also, I added a 1:1 choke balun at the antenna feed point. This antenna served me without issue for years and it was out of the elements from the weather, out of sight and got me on the air. As a sidebar, I only transmitted at QRP levels as I did not want to have any issues with those on either side of us in the townhouse.

Some of the challenges were:
The antenna had a narrow bandwidth on 40m but the Elecraft K3 tuner looked after that. As well using the Elecraft K3 tuner I was able to also use the WARC bands as well.
I picked up very bad band noise from a Plasma TV but that was fixed with an MFJ noise-cancelling unit.
Getting the coax from the attic to the radio room. The room was on the second floor and I ended up putting the coax in the wall and out in the radio room.
Securing the antenna for a "Z" configuration. As mentioned I used electric fence stand-offs. 

Getting the best bang for each watt of power meant CW and not SSB. That began my journey of re-learning CW. Also fast forward to now there is also the digital modes you can use. 

 The next post (part 2) will be dealing with my condo apartment antenna challenges.

Good afternoon all.....The IARU contest has come and gone. This one is a CW and SSB contest but as for me, it was 100% CW. The WRTC (World Radio Team Championship) happens alongside this contest. These folks are the best of the best and competing both in CW and SSB to be the best! This year's WRTC was held in Italy and all the WRTC stations are designed so no one station has an advantage over the other. The power is maxed out at 100 watts as well. For more info click on WRTC. 

Ok well, I am not even close to qualifying for a WRTC team member but I did take part in the IARU contest this weekend. I took part for about 11 hours of the 24-hour contest (social engagements cut into contest time) and for the time I was on the air it was great. Propagation was good and some highlight contacts were KH6, JA, ZL and UP2L in Kazakhstan to name a few. I found my average running (calling CQ contest) speed was around 32 wpm. My contest code practice is paying off as I have no issues when someone comes back to me at 36-38 wpm. I don't call CQ contest at that speed as I feel it limits my score. I have an Icom 7610 at 100 watts with a Huslter 4BTV not a KW of power and huge beams. My best one hour run was 60 QS0's in the log BUT at 2100 things were HOT and I had to pull the plug after 30 minutes and my count was at 50 QSO's. I have to keep my dear wife loving my hobby which means radio does not trump our social things.
I had no technical issues at all....finally and had a great time. 

Good afternoon blog readers I hope you are still enjoying the summer heat and are putting it into perspective as it compares to winters freezing cold? 

I have a question, when it comes to CW contesting…how fast is to fast? I have asked myself this question during CW contests, when I decide to search and pounce most of the time the speed is in around 30-34 wpm. Now having said that there are some big guns that run at close to 40wpm. BUT they have been spotted and always will be thus for the most part then the caller already knows their call. It is just the exchange that has to be handled and if it is a contest that has a generic exchange (CQ zone, ITU zone so on) then the software fills in the exchange details.  

For a small gun like me it’s only now and then I get spotted on the cluster and I know when this happens as I get into a pileup situation. I am not some multi operator high power station with dream antennas I am just small potatoes. I feel that if I was to knock out code at 36 wpm I think my contact rate would drop? In my humble opinion ( please correct me if I am wrong) I should stay in the 30-34 wpm range to gather fish in my net? 

What say you fellow CW contesters…..in a dark place in my mind I am thinking that for me its a waste of time to practice for the 38-40 wpm goal because with my 100 watts along with a simple vertical antenna at that speed I will hear crickets when calling CQ contest? What say you…………

Now it's not a numbers game I play with myself but my goal is to get better at what I do. Improving my skill in whatever it is, is important to me. With Amateur radio CW is my skill and I will be honest I work hard on it and it's nice to see the efforts are being rewarded oh and it's a lot of fun too. To gather as much understanding about my radio, antenna, propagation, pileup skills and the list goes on is what keeps my hobby a busy one and exciting one.
Cheers to the upcoming 6 months of 2023!

 We have had our share of rain over the past 8 days as we are in the middle of a low-pressure system that has stalled out over the Maritimes. This low-pressure system brings cooler temperatures and rain. The upside is the wildfire smoke here is non-existent. We see the results on CNN of the wildfire smoke that is blanketing the central and eastern U.S.

On another note, a funny thing happened today while I was doing my daily CW contesting practice with the G4FON software. It sent me my call sign....I took a double take thinking that call sounds familiar. Then I realized because it was my own. The first time this ever happened. Oh well, it's a way to spend just another rainy day but Saturday we are told the sun will be peeking out from the clouds.  Also, I am hearing the wildfire smoke will subside over the U.S. as well.

Do we need those inline fuses between our radio and power supply, most if not all radios come with them but are they always needed? There was a time when I thought the more fusing the better and safer, but does it add to the safety or is it just redundant fusing? First off let me begin with, this is my own opinion and I do follow it whether you choose to or not it is absolutely up to you. 

I was having an issue with my Icom 7610 cycling off and then back on again while transmitting . The issue was narrowed down to resistance within the cable from the power supply to the radio. I first replaced the poor terminal connections on my Astron power supply. The issue returned again it was then further determined that the guilty party was the inline fuse/fuse holder connection. I cut out both inline power cable fuses...OMG, you say?
Well, not really if (the big if) you have a power supply with very good built-in protection meaning over-voltage protection (crowbar), over-current protection (fold-back current protection), over-temperature shutdown and an internal AC fuse I believe you are good to go without inline DC fusing between power supply and your rig. Again in the background I hear "OMG, you did what"

I do hear some saying "Wait what if there is an issue in my supply line from the power supply to the rig" This is true BUT keep the power cable as short as possible and if you have worries about overheating cables, moving parts or rodents then you have bigger issues than un-fused power cables. Having said that if something between the power supply to the radio power cable causes a sudden increase in current or voltage the power supply protection will quickly look after that. 

 Some who have a large rig such as the Icom 7610 or other manufacturers could be saying "there is no way this rig will be used as a mobile by the average ham but it has fused leads". My answer to that is the big 5 (Icom, Kenwood, Yaesu, Flex and Elecraft)  have no idea what power supply you are going to use. Also, some may opt to use a deep cycle battery at home on a trickle charge or whatever. 

After everything I have said about fuses I am not against them and as a matter of fact I have a Rigrunner fused rail and use it and I am thankful for it. I connect my external ATU, noise cancelling unit and SWR meter (for the light) to it. 

Now if you have no issue with your supplied power to your radio and things are not acting up like they were with me then by all means keep the fused line but for me, some radical thinking cured the problem and some power supply understanding allows me to sleep at night knowing the radio is in good power supply hands.

 I wanted to thank the Dutch PACC contest committee for a nice participation ribbon that arrived today. It was the first time I took part in this contest and it was well-attended and fun. When I looked up my log results I was not able to find them at first. I later clued in that I entered as SOAB low-power MIXED! I have to pay closer attention as I was and always am CW and not mixed.
