Here's what we know about this rig so far...
Little to nothing. Only the scant details outlined in the flyer. It's not even type accepted yet.
We do see a comparison to the IC7200 on the flyer. This could signal a similar price point, placing it either just above or just below the 7200. A 'premium' entry level rig, as opposed to the IC 718.
All mode 7300 vs SSB/CW/AM/RTTY 7200?
Large touchscreen plus FM vs plain display, no FM. Is FM important?
Shiny knobs, lightweight case vs rugged case, knockaround pseudo field enclosure?
The phase noise comparison is probably of little importance to the market at this point, but 7300 promises to be better than 7200. What does this mean to you?
There are a few videos out on the internet that give us an idea of how the SDR architecture is represented in the user interface. There doesn't seem to be anything on the front or rear panel that screams, "SDR". However, the real-time panafall puts this tabletop rig in a different category from any other. This is the first physical manifestation of the conceptual 'affordable' 100w 'SDR with knobs' many have described as their holy grail.
It lacks some features such as separate HF and 6m ports. It does have a USB port that is described as rig control and audio, so it is entirely possible but not probable there will be some I/Q or downconverted IF output available there to feed an external SDR application. Is it more than likely it is just for digi modes?
Is built-in RTTY decode important? RTTY memory keyer?
If the IC 7300 comes in at $1200, does the addition of FM, panafall and large color screen make it a killer? The radio Icom compared, the IC 7200, now goes for about $800. So, they really aren't comparably priced. 33% is a significant difference for a large part of the Amateur radio market, even in entry level and low end base tabletop rigs.
If the IC 7300 can match even the receive performance of a Flex 1500, it will be outperforming (according to Sherwood) currently available rigs of substantially higher price tag, albeit with no frills.
Maybe that's the key feature set of the IC 7300. No frills. Potentially great receive performance. Good ergonomics. Low price.
