Re: FA-VA5 Available No Cost
I can re-home it Tim. I mentor a large group of hams who are interested in antenna work. I am good in QRZ, and would be happy to reimburse you for whatever expenses you incur.

FA-VA5 Available No Cost
I have an FA-VA5 that is not being utilized. I'd like to send it to someone who can use it. I'll pay postage as well.
Let me know if interested. This is not a scam! Check out my call, WB7UVH on

Re: Calibration after 1.09, what is the sign of the correction values ?
Thank you Michael.? I have the paper, and the numbers are negative.? The problem for me, is the statement "negative of the negative of the delays of the standard."? ?I watched a few videos, but

Re: Calibration after 1.09, what is the sign of the correction values ?
Thomas,
this is more a question to the designer of VNWA about his implementation (DG8SAQ). Please note that sdr-kits provides a download link (on the small paper of the kit) to a calibration value

Re: Problem with FA-VA5 connecting with VNWA software
Thanks for the response Rick,
Apparently that driver isn't compatible with Win 11 on my computer as it never showed a driver to download or install. I ended up deleting the CP210x Windows universal

You can go to properties on the "other device" and point it at the
downloaded driver?
Also, Some drivers need to be installed before plugging in a device.

Greetings to All,
I am new to the group and to the FA-VA5. I am having a problem trying to get my FA-VA5 to work with the VNWA software. I have downloaded the software for the VNWA and it seems to

Re: Can the Fa-Va5 be used like a signal generator ?
Frank,
yes, it is possible. At fr, the IF filter will change it's impedance significantly. However, most IF filters are designed for other system impedances than the 'normal' 50 Ohms, which makes SWR

Re: Notes on FA-VA 5 status
One item of the VA5 that really needs improvement is the On/Off switch. The one in all the units I have bought for myself or for other people has proved to be 'touchy' at best, and intermittent as

Re: Can the Fa-Va5 be used like a signal generator ?
Frank,
it is easy:
1. Start FA-VA5
2. Press and hold the left button (about 2 seconds) until the main menu
"Operating Mode" is shown
3. Press middle button [Dwn] quickly three times to move down

Can the Fa-Va5 be used like a signal generator ?
Newbie just starting out -
I heard that the Fa-Va5 can be used like a signal generator ?
I looked at the operation manual and it looks like it has a very steep learning curve.
Can anyone out there

Re: Successor to FA-VA5 (long!)
I guess it's time to wade in.? I've been making transmission line measurements since the days when I used a waveguide reflectometer and "calibrated" a scope screen with a grease pencil.

Re: Notes on FA-VA 5 status
Hi Charlie,
thanks for your input. Some comments:
50 Ohm/ 75 Ohm
There is an option in the setup to change to 75 Ohm system impedance. Of course, this will not change the hardware of the bridge, but
