Frans improves connections to his Hurricane Transmitter

Many thanks to SWLing Post contributor, Frans Goddijn, who writes:

Here’s a little follow up on what I did earlier with the little Hurricane transmitter.

Before I had an ‘indirect’ connection between antenna-OUT of the transmitter and the radio as I had two insulated wires , one from the transmitter, one from the radio, taped close to one another.

Now I first tried a direct coax cable from transmitter-OUT antenna to receiver-IN antenna. That worked well if I took care to not amplify the incoming signal too much.

Next I made a one-off three-way antenna switch into an all-three-way connector.

Then I sent sound/music (by Joe Frank) from the iPhone to the transmitter, to all three radios.

I first listened to each radio and in the end had all three playing the sound.

A pleasant way to listen to some of my favourites!

Best regards,

Frans

I love this, Frans! And what a great music selection to test the new setup! Thank you for sharing, OM.

Dear Thomas,

In the following video, I show a little loop antenna that I bought online from AliExpress:

On arrival one of the parts, the semi-transparant box with variable capacitor for antenna tuning turned out to be broken due to the bigger box having been thrown around in transit.

The seller promptly provided me with the necessary part (plus extra) for repairs.

Yesterday I repaired it and today I assembled the antenna and tested it a bit in the afternoon and early evening as soon as reception started to get well enough.

It’s a fun antenna, affordable too.

The video shows how effective the variable capacitor is.

Best regards,

Frans

Thank you, Frans. That is certainly a very affordable passive loop option. If you’re an urban QRPer, all the better. I should also mention, you have one of the nicest radio operating positions out there!

Frans purchases the Hurricane AM Modulator

I bought the Hurricane AM Modulator.

Here in my living room the hum was considerable even though I had an EARTH connection. So what I did was use a coax cable made of two different ends of coax cable, just the isolated kernel of both taped close together so the signal is transmitted on one, received on the other without the wires touching. One end in the antenna OUT of the transmitter, the other end in antenna IN of the receiver.

Now I can wirelessly send music from my laptop or telephone to the Hurricane and ‘receive’ it on the radio of my preference.

The HUM obviously does not originate from the Hurricane.

Thank you for sharing this, Frans. The Hurricane sounds amazing via that gorgeous Hammarlund SP-600!

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!

The AMT-MW207 mini AM radio transmitter kit

9 Replies

Many thanks to SWLing Post contributor, Frans Goddijn, who shares the following video demonstrating the AMT-MW207: a tiny $25 mediumwave transmitter kit that can be purchased on AliExpress:

To be clear, the AMT-MW207 is not designed to be a whole house AM transmitter like the SSTran and others.

The seller describes it as a device to debug and test AM receivers. Since it only employs a built-in bar antenna, the transmitter would need to be placed in close proximity to the receiver.

Thanks for the tip, Frans!
