February 2017. Sold my Icom IC-7600 and replaced with a FlexRadio 3000. The 7600 is a great radio but after playing with the SDRPlay receiver since it came out I really wanted a SDR Tranceiver. The radio has not been manufactured by FlexRadio for a few years. In the links below I am gathering together everything I can find on the 3000. Come back often.

My current setup, above. The 3000 uses the same microphone connection as Yaesu. Since I recently purchased a Yaesu FT-991A and have a microphone setup using a Radio Shack 33-3042 dynamic microphone, I found a 2 position A/B switch box on Ebay for $6.98 and FREE shipping. Add 2ea, 2 foot shielded CAT-5 patch cords from SF Cable and you have a great A/B microphone switch.

So far the only downside is the Noise Blanker in the 3000 is no way as good as the 7600. Below is a suggestion from KE9NS that is a good place to start:

"I think that you need to set the setup->DSP->phone->RX butter size low to allow it work.
If you keep the RX buffer big 2048 or 4096, you get super sharp band pass filtering, but it messes up the NR and ANF. Not sure why.
If you set the buffer to 1024 or smaller, NR & ANF will work better. Then you can set the TAPS big so the NR can work out the noise better. If you try a high TAPS while running a big RX buffer, its really bad. NR seems to work better in AM than SSB."

One of the great things about Software Defined Radio is the ability to make "virtual" ports. Most of the above links recommend the Com0Com virtual serial port software and the Virtual Audio Cable program to create audio ports. VAC worked great for me ( Probably because it is not free? ) but Com0Com was a complete bust.

Thanks to Google I found VSPM ( Virtual Serial Port Monitor ) by K5FR. Worked great for me for HRD and Winlink.

A Voice over IP (VoIP) application primarily designed for two-way amateur radio remote control over the Internet I haven't tried this yet but gets good reviews.
