This is my friend Duncan calling CQ on various frequencies and having QSOs with many stations including myself.
Go to 2:40 min and you can see and listen how I was heard in Scotland.

I went out without checking the Solar forecast can ended up calling CQ during a radio blackout. The livestream ended up with a few surprises from some of the...

For everyone that wants to connect an old rig with a today's app, follow the instructions of Mr. Steve Brightman given in a webinar. You may find it on YouTube, if you search for "SDRplay Panadapter Webinar".
In my case, I control the Yaesu FT 2000D using the SDRuno app and the RSPduo receiver.

16/03/2024

Following the suggestions of a fellow ham, I made these connections from the RXout to the RXin, using this T connector. So as long as I have the RX antenna selected, the signal feeds both my RSPduo SDR and the 2000's receiver.
Below a small sample video.

It is not only an Amateur's new toy. It's the way to communicate and send even spreadsheets over the air, at 128 kbps, WITHOUT internet. Imagine that.

Comparison in 21 and 18 MHz bands in USB between Kenwood TS 2000 and Icom ic 7300. Both rigs share the same antenna and their filters have the sam settings.

A comparison at the reception between the 3 rigs, using the same antenna and an antenna MFJ 1704 swich.
It must be mentioned that the antenna is NOT suitable for these frequencies. The wave length (λ) here is more than 3.868 m.
However, the Kenwood outperforms both the Icoms as you can hear.
Μια δοκιμή λήψης μεταξύ των 3 μηχανημάτων χρησιμοποιώντας την ίδια κεραία και ένα διακόπτη MFJ 1704.
Πρέπει να αναφερθει πως η κεραία ΔΕΝ είναι κατάλληλη γι αυτές τις συχνότητες. To μηκος κύμματος (λ) είναι περισσότερο από 3.868 m. Εντουτοίς o Κenwood υπέρτερεί έναντι και των δύο Icom.

In this photo there are 3 traces.
The Yellow one is the SWR.
The Green one is the Smith Chart.
And finally the Blue one is the Reactance.
As many should know, the resonance frequency is at the point where reactance is 0.
So, the resonance frequency of this antenna is (almost) at 24.740 MHz, where the Reactance is -985 mΩ, (can not pin point the exact 0), the SWR 1,37:1 and the Z 36,3 Ω.
At this exact point the antenna radiates the max and the frequency IS NOT where the SWR is 1:1.
