A photo tour of the 2022 Shelby Hamfest

On Friday, September 2, 2022, I had just enough time in my schedule to visit the Shelby Hamfest for a couple of hours.

The Shelby Hamfest–referred to, locally, as “The Grand-Daddy of them All”–has long been regarded as one of the largest outdoor hamfests in the southeast US.

Weather was ideal for the hamfest: clear skies, sunshine and very dry. It was quite hot, though! Attendance was much lower than I’ve ever seen at the Shelby Hamfest in the past, but then again this was also my first Friday attending; typically I visit on Saturday which is historically the busiest day.

Dan reviews the new Chameleon CHA RXL Pro Wideband Magnetic Loop Antenna

The Chameleon CHA-RXL Pro:  Improved Amp Board Raises the Game

by Dan Robinson

Back in 2021 I reviewed the CHA-RXL loop by Chameleon.  This loop antenna is sold by major retailers such as DX Engineering, Gigaparts and Chameleon itself – the company is a well-known name in antennas and other equipment for the amateur radio world.

I compared the CHA-RXL to Wellbrook 1530 and W6LVP loops feeding into a four-position Delta antenna switcher, and then to a Raven 16 port multicoupler which maintains good steady gain.

My Wellbrook is mounted on a telescopic mast about 15 feet above ground level, with a rotor.  The W6LVP (using LMR400 coax) is tripod-mounted with an overall height from ground of about 12 feet. It has special filters to prevent strong medium wave signals from bleeding into HF.

I have since added a UK-made loop (essentially a copy of a Wellbrook loop but smaller diameter and made of metal) combined with a W6LVP amp.  This W6 amp does not have filtering to block strong mediumwave signals.  In all, I have four loops into my Delta switcher, which feeds about two dozen receivers.

There is by the way quite robust discussion at https://groups.io/g/loopantennas about various loops, including the Chameleon.  And this past July, Steve Ratzlaff posted news about the upgraded loop amp board which will ship with what is now the CHA RXL Pro, saying:

“Chameleon has completely redone their CHA RXL loop amp board from the previous poor-performing loop amp that I tested some time back, and sent me one of the new production boards to test. I’m happy to say it tests very well especially for LF sensitivity, and I can now give it my “seal of approval”.  The new board is a version of the LZ1AQ loop amp.”

It turns out, according to an email from Don Sherman of Chameleon, that Steve is one of the engineers who helped design the new amp board for the CHA RXL Pro, and on the Loop Antenna group he provides a folder in which he placed previous test results with “new files of the new board (sweep of the new RXL Pro loop amp, and a picture of the new amp PCB).”

Music from out of the KFOG

Hi SWLing post community, hope you are all well. This weekend there’s another in the Imaginary Stations series, this time the return of KFOG. The transmission will be on air on 9395 kHz from 2200 utc on Sunday 4th September 2022. Expect tunes in a nautical style. It will feature “music from out of the mist” as they say at KFOG HQ.

RNZ Pacific resumes shortwave analogue service to Pacific region

RNZ Pacific resumes shortwave analogue service to Pacific region (RNZ)

From September 1, RNZ Pacific will resume its shortwave analogue service to the Pacific region between the hours of 5 and 9am New Zealand time.

Shortwave radio is radio transmission using shortwave (SW) radio frequencies.

RNZ Pacific broadcasts in digital and analogue shortwave to radio stations and individual listeners in the Pacific – the digital service is available via satellite and the analogue shortwave can be accessed by anyone with shortwave radio.

The AM service during the breakfast period was stopped in 2016.

The resumption of the analogue service will allow listeners in remote locations with a domestic shortwave radio to hear RNZ Pacific 24 hours a day, made possible with extra funding from the New Zealand government.

RNZ Pacific will run three different frequencies at various times, at 5am NZT tune in on 7425 kilohertz, at 6am NZT listen on 9700 kilohertz, and at 8am NZT change the dial to 11725.

For our full schedule of shortwave frequencies check out the RNZ Pacific website.

The DRM digital service during breakfast hours will continue on transmitter two for our partner stations around the Pacific region.

RNZ Pacific’s flagship daily current affairs programme Pacific Waves is widely listened to across the region and is also broadcast by the BBC Pacific Service.
