Well, after looking at them every day for a year I have finally ordered a Flex 6400.
I know none of you have purchased a radio because you did not need it
but you wanted it?

New Flex 6400 tucked under the bench. It's a network appliance.

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.

Transverter

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

2023 Purchased a 1500 from a local Ham. I love the PowerSDR software and the features the current Flex software
is missing. With 5 watts to my Elecraft KPA500 amplifier I get a 100 watt radio.


My previous Flex 3000

Well, September 2023 found another 3000. Wow. The KE9NS software does a better
job of noise reduction than my 6400. Enjoying a 3000, again.

Remote Control

Many Flex users have extensive remote control systems for their radio, antennas and rotors. 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.

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.
