Petition to change the way the FCC deals with RFI

FCC LogoThere is a petition to change the way the FCC deals with RFI complaints at whitehouse.gov.  Please consider signing it.  Please click here to sign the petition.  You will be taken to the whitehouse.gov site to sign the petition. The petition is directed at all Amateur Radio Operators within the United States, asking that the current administration vigorously suggest to the FCC that they change the RFI complaint process to take the Amateur Radio Operator reporting the RFI out of the door knocking part of this process. Currently the Amateur Radio Operator experiencing RFI must locate the RFI, make sure the location provided to the FCC is correct, and then submit the RFI report to the FCC.  This can involve knocking on doors, asking the party, or parties who may be generating RFI to power their house, or home down.  This process can put the Amateur Radio Operator(s) looking for the RFI in a perceived enforcement role in the eyes of the person generating the RFI.

ARRL to FCC: “Grow Light” Ballast Causes HF Interference.

ARRL to FCC: “Grow Light” Ballast Causes HF Interference, Violates Rules.

arrl-smallOn March 14th, the ARRL published an article stating: “ARRL formally complained to the FCC, contending that a “grow light” ballast being widely marketed and sold is responsible for severe interference to the MF and HF bands”.

In a bold move, the ARRL complained to the FCC regarding Grow Lights and the RFI they generate.  The ARRL included extensive lab reports on a single lamp unit showing HF interference beyond commission set limits.  See the this article on the ARRL web site for full information. Read more »

Review of Ameritron’s AL-82 Amplifier

Ameritron's AL-82

Ameritron’s AL-82

After several years of use, this review of Ameritron’s AL-82 amplifier seems long overdue.  I have owned the AL-82 for three years now, and over that time, it has given me incredible performance on all bands.  This review will not be a technical review, it will in fact be a general observation and usage review.  Questions like:  does the amp hold up, does the amp work, does it run hot, is it easy to tune, etc., that sort of review…  All comparisons will be based on my ownership of the following amps: Heath SB-220, Heath SB-200, Drake L4B, and a Gonset GSB-201.  All amps but the Gonset were wired for 220 VAC, not  110 VAC.  All amps were run in desktop service.  ie. not in a rack with additional cooling, just sitting on a desk.  All amps were used in contest service.  We need a base to compare amps with, so we will break the amps into the following.

Review of ‘The Daily DX’

The Daily DX

The Daily DX

I wanted to actually use “The Daily DX” for a year prior to reviewing it, that way, I could actually speak from a position of knowing what I was talking about, and not just mouthing a review of it.  I tried the free two week trial.  The Daily DX provides.  When I signed up it was on the order of 49 bucks a year or around fourteen cents per day.  The daily DX is a DX newsletter that comes out pretty much every morning at 4 AM PLT.  It comes out as email, and is very topical.  The first question to answer is “Was it worth it”?  The answer is yes, if you like DX.  If you are not interested in DX, then skip “The Daily DX”, it is not for you.  If on the other hand you want to know what is happening in the world of DX by all means subscribe.  If you have the slightest interest in DX, you should subscribe.  I initially subscribed to do the review, I have however now renewed my subscription as The Daily DX has actually helped me get more DX!  For instance, today, it noted that the Vatican would be active for a 10 hour period…  I have not seen this information anywhere else, just in The Daily DX.

Review of N3FJP’s AC Log 4.x

 

Overview:

This is the review of N3FJP’s AC Log, One of the best logging program available just got better!  Scott Davis, (N3FJP), has announced his completion of the rewrite of the popular logging program called “Amateur Contact Log“, version 4.0 from Visual Basic to the C# language, moving the version number from ACL3.4x to ACL4.x.  See my review of ACL3.4 here.

Alas, I had hoped that the next rewrite might make it possible to port to Linux…  This rewrite does not do that, (thank you Microsoft), but, it does run under VirtualBox, and I hear under Wine for Linux as well.  So it looks as if I will be keeping  my VirtualBox Windows XP box for a bit longer…

Overall the program seems more mature, the look and feel are better, the fonting seems better, but there are a few foibles in it yet, not many, and nothing bad so far.  Overall the program is well written, seems a tad bit slower than 3.4, (which is not a surprise), but has several new features which make it a good change.  Best of all, N3FJP makes the update available free to registered users.  Something that surprises me.  Most vendors will charge for a major version change.  Perhaps given that this was not really a massive change, (to the user, but a total re-write to the author), no charge was levied.

Phased arrays for 40 and 30 Meters – 1

Overview of Lot

Scaled view of project

Introduction:

If  you look at this site, you will see that I have been fighting an RFI problem for years…  For the most part I have it beaten down, and it seems to not be coming back…  So…  That said, I decided to construct a four square array for 40 meters, and a two element 30 Meter phased array, so I could null the remaining RFI, and gain some signal too boot.  This also gives me a decent 30 meter Antenna array as well…  A four square system is not a small project, you need four verticals, miles of ground wire, a phasing unit, and some land, couple that with a two element 30 Meter phased array and you end up needing something like two miles of ground wire, and five antenna…  For the past few decades I have been threatening a 40 Meter phased array, maybe two elements, maybe parasitic, or maybe driven, I never really committed.

I had a failed tower project, and found myself with a slight surplus of money after I sold everything dealing with the tower…  The cash I was going to use for the tower, could be redirected to the four square project.  So I decided to build a phased array for forty and 30 Meters!  As I see it the pros/cons as as follows: Read more »

Review of DX Engineering’s Radial Plate

DXE-RADP-3

DXE-RADP-3

This review of DX Engineering’s Radial Plate was prompted by the installation of a Four Square array, and a two element 40 Meter vertical array at NK7Z.  I decided to evaluate each item in the building of the arrays separably, then review the entire system as a whole later.  Years ago I had promised myself I would never spend fifty bucks on a piece of metal with holes in it.  After making the decision to build a Four Square for 30 meters, and a two element phased array for 40 meters, I decided to revisit that decision, as I had a lot of ground radials to lay and connect to antenna bases.

My plan was to buy the needed parts for a single monopole, construct it as perfectly as I possibly could, and then duplicate that process for the other five antenna.  Part of that process was to buy a radial plate for the ground radial system so I could keep all of the wire under control…  I bit the bullet and bought one!  I was pleasantly surprised when it arrived, it is so pretty…  So perfectly built…  So heavy…  I actually didn’t feel so bad about spending fifty bucks on a piece of metal with holes in it!

The photo above, and on the DX Engineering web page does not do the plate justice…  It really looks a lot better than the supplied photo from DX Engineering.  The surface is smooth, the holes are sharp edged, and perfectly lined up, and in general the construction is a 10 out of 10 for quality.
