Both USB cables are autosensed by the computer and work fine with Win10 to check the software versions in both tuner and amp.
But when trying to complete the Tuner/Amp install into SmartSDR v2 the USB Cables are not to be found under Settings-->USB Cables...
Ideas please? TNX Dave.
The USB cables for the back of the Flex radio must have the FTDI chipset. Is it possible that the Elecraft cables are not FTDI?
If you don't see them in Settings, but might be something to consider.
You can test this by installing those same cable in a PC, then go into the Device Manager and then inspect the cables to make sure they are not the Prolific chip set.
That is the first thing I would look into.
Elecraft has this 'kit' specifically to hook their Tuner/Amp to the FLEX 6000 series. (It is an xlnt combo btw. I have used it earlier without this auto-tune cable upgrade.) -Dave
Honestly, though, I stuck with the PC connection for the remote software. Both the KPA and KAT do a fine job without direct integration to the Flex.
The system may in fact be working as designed, simply not as I anticipated based on instructions. The bands do change with changes in SmartSDR if:
1) The TUNE button is pressed, and
2) The TUNE power setting is larger than 0.
But that is no different than before without the extra cables.
ELECRAFT document E740349 rev C, part of what I used for the install says "As you tune your transceiver, the KAT500 will follow and automatically select the correct ATU tuning solution, EVEN BEFORE TRANSMITTING."
Does TUNE above mean to change frequency or bands, or to apply RF power? I had presumed the former. Tuning with any amount of power is called TRANSMITTING.
As of now actual RF based TUNING is still required to change bands. I had assumed the amp would track the 6000 'automatically' and without manual
intervention but that isn't happening.
This is where I am stuck...
I run the KAT500 in MAN (Manual) as recommended. As I tune the 6500, the tuner follows and can be heard changing the tuning, without transmitting. The KPA500 changes bands when I change bands on the 6500. I am using the Elecraft supplied cables and the null modem adapter for the KPA500
Here is a screenshot of the Flex USB cable settings for the KAT500. The KPA is essentially the same.
There is no shortage of real estate on the back of the 6400 so why not use a connector package with more spacing on future products? -Dave.
