Frans add a Decca manual antenna tuner to his urban listening post

Hi Thomas:

I bought a vintage antenna tuner, one that does not need a power source, very basic just a box with some beautiful coils and nice big variable capacitors and it works for the big magnetic loop antenna here.

I have four GRAHN loop antennas which each have their box with dials to fine tune the signal but the big loop didn’t have that yet.

The tuner works well, filters out some noise but I must say the iCOM radio also managed to select good signal from the loop with its own tuner system and the DSP noise filter at the speaker end of the system further clears up the voice sounds.

Best regards,

The internals of manual antenna tuners are simply hypnotizing, aren’t they? You’ve a beautifully-built tuner there that is functional and will outlive us all!

Thank you for sharing!

Hello Thomas

I recently got a new Icom 9500 and have made several in depth videos on it for my YouTube channel including multiple direct comparisons to other premium receivers.

Here is the main overview video:

Thank you for sharing this, Nick. The IC-R9500 is an impressive receiver indeed!

Video: Giuseppe’s “Cassette Loop” on the shortwaves with induction

Dear Thomas and Friends of the SWLing Post,

I’m Giuseppe Morlè from central Italy, Formia on the Tyrrhenian Sea…

My Cassette Loop experiment this time shows how induction takes place on short waves after medium waves.

I used a smaller box as the primary antenna which, however, is pushed by the secondary one due to the induction effect generated between the two windings brought closer together.

This way, the larger loop “captures” more of the signal and sends it to the smaller cassette…

I really like working on induction… I hope you like it:

Video: Giuseppe tests four classic receivers on three different antennas

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas and Friends of SWLing Post,

This is Giuseppe Morlè from Formia, central Italy on the Tyrrhenian Sea.

I want to share with you this test with 4 old receivers with 3 different antennas:

    • Yaesu FRG-7
    • AOR 3030 – MINI WHIP antenna on the roof
    • Kenwood R-1000 – INTERNAL CROSSED LOOP antenna
    • Yaesu FRG-8800 – VERTICAL NAVAL

I tuned the 7,390 kHz frequency of Radio New Zealand at 14:10 UTC on November 16 on the 4 receivers. I used the narrow and wide filter on each receiver.

I state that a storm was in progress in the area, the afternoon signal was very discontinuous with a difference on the 3 different antennas.

Surprising the result of the internal cross loops which I use a lot when there are thunderstorms in the area to listen to anyway; their behavior is definitely very good despite being inside my shack.

The Mini Whip is excellent on long and medium waves but gets worse above 7 MHz. In fact I only use this antenna for medium and long waves.

A good signal also from the external naval vertical of 8 meters with a “soft” listening on the Yaesu FRG-8800.

Judge dear friends your comments are welcome!

I wanted to compare these 4 “glories” that have accompanied most of my life and that I still consider excellent.

I wish everyone a good listening …

Thank you so much for sharing this, Giuseppe! We love your videos and demonstrations especially since they so often involve antennas that you have home brewed. Your cross loop antenna is truly amazing!

Dan, I’m not sure how you find these things, but wow! I know you had a lot of fun unboxing this NIB WJ 8711A! How amazing it is to turn on a radio like this that’s been in the original box for two decades!  I hope you have a lot of fun with it on the air. Thank you for sharing!

Hi Thomas

I just picked up a new to me radio that [is] very rare in the US.

I loved it so much I did a comparison to an 8711 and a FTDX101MP. The Skanti presented very well.

Excellent Nick! Thank you so much for sharing this and for demonstrating some weak signal work. You were certainly pitting the Skanti against some benchmark performers!
