S’il fallait une preuve de plus que les antennes vendues à très bas prix sur les sites de vente en ligne asiatiques sont loin d’atteindre les performances annoncées, vous la trouverez ci-dessous.
N’allez cependant pas croire que les antennes moins abordables sont de meilleure qualité… Ah, et méfiez-vous aussi des commerçants en apparence plus sérieux qui revendent la même m****. |
I’ll probably update this procedure with a nice PDF document, as usual, but for now you’ll have to settle for this.
UPDATE: You can now edit the codeplug with a hex editor and keep all your presets (config & channels).
UPDATE 2: I’ve performed a very quick TX/RX test on the 200MHz band with a R&S radio service monitor. Jump to the end of this article to learn more.

So, I’ve designed a small tube that holds the SMA to FME adapter on the inside, and that provides wide contact area on both ends: my Procom FSP70’s antenna base and the MD380’s SMA socket. It just took me less than 2 hours from scratch to draw and print that little strengthening piece. Click « Read more… » to see the result and the gcode file download link: |
