Where and when can I purchase one?
Anyone know when and where will it be available for purchase?
How much for the Q900 SDR transceiver?? and when is it available ????
If it had DMR, OpenDV and Ethernet I’d buy it
WTH do I get one?!? It looks like it is worth a shot.
The price looks GREAT! …wonder what the modules cost?
…BUT, unless they made typos, you Lose Out with less coverage on 80, 40 and 70cm (not that I frequent 70cm often).
Still, $380 bucks isn’t bad to play with SDR and get HF and VHF with Bluetooth and good software options!
Interessantes Gerät, der Q900. Würde ich sofort kaufen.
A UK ham who reviews kit for one of our mags was sent one for review. It was so bad that he just returned it without writing the review.
