Re: Anvelina SDR transceiver by EU2AV

Carried out 2 more improvements: 1) Added a variable resistor to the circuit to adjust the fan speed in reception mode. Reduced the speed, the noise of the fan decreased, and the air flow did not feel much changed. Taking into account the modernized gaskets for the radiator, about which I told the t...

Re: Anvelina SDR transceiver by EU2AV

He specifically paid attention to cable management. All signal wires passed through the copper sleeves. I took the braid from the RF cable. I tried to spread the wires around the perimeter of the case, and so that they did not interfere with the flow of air from the fans. He put ferrite rings on the...

Re: Anvelina SDR transceiver by EU2AV

Then I wanted to see the scatters under the antennas of the SO239 sticking out from the inside. See photo. To do this, I had to cut off part of the power amplifier board in the contact area where the wires are soldered to the SO239. Photo. The inside of the back wall of the case was cleaned of paint...

Re: Anvelina SDR transceiver by EU2AV

There were gaskets, but I wanted to increase the contact area of the heating parts with the main radiator. After this refinement, the rotation speed of the fans decreased, and the background noise from them at the reception decreased.

Re: Anvelina SDR transceiver by EU2AV

I received many different cables, connectors, adapters in addition. The work boiled over. I want to immediately warn you that the transceiver is going into the case and works perfectly without improvements, without finishing, but I, only for myself, decided to make some improvements in my opinion. G...

Re: Anvelina SDR transceiver by EU2AV

Hello to fans of transceiver Anvelin pro 3. Today I want to talk about my build version of this wonderful transceiver. The beginning of this whole venture appeared in January 2022. And the end of the project, before the last screw is twisted, in September 2022. I learned from my colleagues of radio ...
