I have both of these new sdr rigs and have been enjoying them for a while. First the Icom 705, its a mini 7300, same display, its an SDR and has a lot of the same Icom menu/operating setup which is very good. It is NOT a little 7300 though, it does not modulate as well, nor sound as good with the supplied microphone. It has a speaker/mic setup with a 1/16? trrs jack for the mic and a 1/8 trs jack for speaker/headphone/microphone speaker. Audio has the same limitations as the 7610 and 7300, nothing below 200 Hz on RX or 3000 Hz on TX, but I think the TX goes down lower then 200, maybe to 100 Hz. Within those limitations the RX audio sounds very good and clean. TX power is 10 watts pep, 5 watts pep with the built in battery. On AM, you only get about 75% modulation no matter what the power, and the supplied speaker/mic does not sound very good despite the ability to adjust the lows and highs in the radio menu. It does 160 meters to UHF and all modes plus repeaters and digital voice. If it worked better on AM it could be your entire station if fed into an amplifier. The 7610 is better, but then it should be for its size and price. The display is great, the ease of use is great, you can watch 2 bands at once and switch between them very quickly. The audio on RX and TX is the same as the 7300, not bad for an Icom, not very good for AM. I do find the 200 Hz rx audio cutoff not as bothersome as I would when my hearing was better, it helps with the copy. That is one big flaw in my book, on the TX side it does not matter much, its a 25 watt radio and at 25 watts you likely want restricted audio to punch through. Not the rigs to put into an amp for good hifi AM. I find myself liking the 7610 a lot. Its really nice sounding on strong signals, on weak signals the agc tends to boost the noise as many sdr's do. The RF gain helps there.
