Yes I have a couple of them, I have been playing with the hacked firmwares. SSB RX is surprisingly good. Not extremely sensitive when out of band (2/70), but amazing for what it is. Down to 18MHz and up to 900MHz, it hears things "OK".
I am using this firmware: "fagci-mod-v1.2.1-b6-regs.bin" - the latest with SSB support as of now.
Notes:
- Its SSB RX is in Double Side Band (DSB). (It will RX LSB and USB).
- It can TX a 'sort of' DSB signal, when you lower the DEV settings in the modified firmware. It still has some carrier but it can sound "OK"...
- It is NOT going to TX nicely out of band, at all, no matter what you do with firmware. The TX power on the fundamental frequency out of band is usually lower than the power of the harmonics!!. Please DO NOT try and use this radio as a TX on CB for example. You will see only microwatts (yes) on CB and WATTS elsewhere as harmonics, potentially in government and emergency services bands. You have been warned!
It's a really cool experiment and more firmware is coming. Hopefully the hardware guys will catch up soon and we might be able to improve out of band filtering. Pretty cool for the price and a bit of fun, bugs and all.
What the world needs and doesn't really have right now, is SSB handhelds! This could be something that helps push that along...
