    SunSDR2 DX HF Ham Radio Transceiver - today I setup a new HF radio from SunSDR, the SunSDR2DX 100 watt Transceiver running ExpertSDR software. A special thanks to the nice folks at Gigaparts for allowing me to review this radio!

    Nice radio, I imagine it would certainly have excellent filtering abilities.

    They are mini-UHF and SMA for others I believe.

    This is correct. Mini-UHF. Same connection used by many Motorola mobile radios (not that that means anything, just relating it to that same style)

    although I would rather have SMA connectors, not a big deal.

    The advantage of mini UHF is they aren't much bigger than the coax, so installation is easier, drill one smaller hole. Otherwise, not compelling.

    Interesting looking SDR radio. Have you had a chance to compare it to the Flex Radio SDR?

    Hi Cliff (neighbor)- Yep, and the mini-uhf ports are certainly more robust than if Sun used SMAs. SMA to SO239 adapter or pigtail, and then to a 'good run of coax' would likely have operators stressing the ports. Regarding Ant port 2 & 3: Sun will relabel these as A2-"HF/50" and A3-"HF/50" in the next production run, and Ant 1 as A1-"144"...hi
