For some reason Flex decided to abandon the Yaesu "standard" microphone jacks and replaced it with an 1/8" stereo mini plug. They said it was for cost savings but my 3000 had a pick in place RJ45 jack that had to be almost as cheep as 1/8". Anyway...... I built a Y on one end of a shielded CAT6 cable to connect to the 1/8" for microphone and an RCA plug for PTT. The other end is plugged into my switch box. Since I recently purchased a Yaesu FT-991A and have a microphone setup using a Yaesu MD-100 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.

Flex has a great Transverter output. I am using the 2 Meter product from Ukraine. Unfortunately till the war is over he cannot ship any product. However a Google search will find lots of other vendors.

My Flex 1500

My previous Flex 3000

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. ( In June of 2018 I sold the 3000 to a local Ham and purchased a Flex 6400. ) 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." Flex Links 6000 Series FlexRadio Systems Website FlexRadio Systems hints forum.

I just wanted something to turn on/off and re-boot the radio when I was operating remote. The Flex Community have come up with the solution below. It's cheep and works well. If you already have other remote Internet Of Things ( IOT ) plugs in your house you could use them with the relay module. Connect a jumper with bare wires on the NO and Common on the relay module. Put an RCA plug on the other and connect that to the Remote RCA connector. Use the their app to turn your radio on/off remotely.

Setting Transmit Audio Gain Distribution in PowerSDR - W1AEX Another – Power SDR Transmit Audio Settings 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.
