I spent some more time over at N6RO with Ken, N6WM and N6ML, replacing the 20M rotor. As we got to talking, I decided to voice some of my problems, since I am still a bit lost when it comes to troubleshooting some of the ongoing problems I have in the shack. The first and most important was the RFI that bit me a few weeks back at about 500w. While I have added some ferrite toroids to the NID that AT&T has their equipment in, this has not solved the problem of about 500w of power reflected when I have the Alpha 76PA on.
One of the first adjustments I made was to move the hex beam (again!). Thanks to N6WM, I now have it mounted close to 20′ when I am operating, but it is closer to the shack. Actually it is mounted on the exterior wall off the shack. I need to upgrade the stock RG-8 coax and solder on some good silver PL-259 connectors, as K3LR does at his station. I also need to added some tinned copper braids as grounds from the amp, rig and power supply to the copper grounding bar.
I finally measured the SWR of the hex beam and the measurements were relatively flat across each band, only starting to climb above 1.5 near the edges on a few bands. I know I am loosing quite a bit with the bad cable, but I am not able to use the LMR400 I have on the SteppIR, since it is buried in conduit. I figure 35-40′ should work.
All this work and adding more 33′ long radials to the BigIR are on the list of things to accomplish before SS SSB in about 2 weeks. I am hoping to get the coax on Saturday and add the PL-259 connectors to it and test it. The ground straps won’t arrive until next week from DXE. If I am still having reflected power issues, then I will have to call in “the experts” to stop over and see what else is incorrect in my shack set up.
If there is anytime I need the amp to perform it is in a SSB contest. Sure I could go < 150w, but I want to push legal limit. I am still reviewing my performance during the CW portion of SS and wanting to implement some changes. While I am still going to set my personal goal high, there are a few things I want to accomplish. One of those things on the list knocking off the states I need for 20 and maybe 40M WAS. I would like to really push for the “clean sweep” since I missed out on it for CW. I was 10 sections short and outside of 2 of them, I probably could have worked the other 8.
Speaking of fix’er up, I have finally updated the Contesting page. While my claimed scores are nothing worth of recognition, I have listed all the contests (outside of a few) I have participated in. I am hoping to use these as a baseline and work on improving these scores. Some of the scores…well many of them are not worth even mentioning, but a contesters has to start somewhere. Since I don’t have weekends off and time to dedicate to 24-30 hours of straight contesting, I will take whatever I can get, whenever.
