Receiving LW AM Broadcast band in Macedonia with RSPdx [00:04:46]

As you can see and hear in this video, reception of the Long Wave AM Broadcast radio stations with SDRplay RSPdx is excellent. The sound is crisp, clear and very good thanks to the large HDR capabilities of RSPdx receiver and SDRuno software DSP features, with a large number of predefined filters and opportunities for their customization also. The video practically shows how filters can be manually adjusted to avoid interference from the neighboring very strong signals in adjacent channels, giving a much better sound to the desired radio station. Watch the video and see for yourself, especially in the second half of the video, where I am playing with filters and adjusting them according to situation...
The Receiver is SDRplay RSPdx, and antenna is homemade Mini-Whip active antenna, only 10 cm long, mounted on a 6-meter high plastic telescopic mast.

CQ WW DX CW Contest 2019 Receiving with SDRplay RSPdx on 14MHz [00:07:55]

CQ World Wide DX CW Contest receiving with SDRplay RSPdx receiver on 20 meters band. Plenty of signals here in Macedonia, with excellent conditions and brilliant SDR-receiver. In the middle of the contest, In very difficult conditions for any receiver, RSPdx was a real pearl, extracting weak DX-signals very successfully. Watch the video and see for yourself. You can see and hear many DX-stations from all over the World, received at my home in Macedonia. On this video I am using Mini-whip active antenna, which I made it myself.

The New SDRplay RSPdx receiver — First Impression: Excellent! [00:07:01]

Today i have received the new SDR receiver from SDRplay, the RSPdx and was eager to turn it on and do some tests receiving on HF and VLF. Although at the moment my mini-whip antenna is not operational, I have connected some 20 meters wire as an antenna and start listening on VLF, LW, MW and HF...
I have to say that SDRplay team did a good job with this SDR-receiver, putting better filters and redesigning front-end to improve dynamic range and enhance overall performance in relation to its predecessors RSP2 and RSP2pro. The new RSPdx is very good indeed. Especially on HF and below.
The RSPdx has new features like HDR (High Dynamic range) mode for reception within selected bands below 2 MHz. HDR mode delivers improved intermodulation performance and less spurious responses for those challenging bands.

9A0BXV in JN74LT 10GHz beacon Oct.6th 2019. [00:00:42]

Automatic Programmable Beacon 4kHz to 225 MHz with Arduino & Si5351 [00:03:32]

This is Programmable Automatic Radio Beacon made with Arduino NANO and Si5351 chip.
The RF output power is only about 10 mW, but it can be increased with additional RF amplifier.
Can be programmed to transmit in 4 kHz up to 225 MHz frequency range, with different speed of Morse keying and any transmitting message ...
It is very cheap! The material cost is only about 5 US dollars !
