Successor to FA-VA5 (long!)
Hello Michael, Thank you for your message on the status of the FA-VA5. I waited some time to see if someone else responded first but I see no response. There was also QRL (which is such a time sink!)

Notes on FA-VA 5 status
Dear FA-VA4/FA-VA5 users, some of you discussed in the forum that the FA-VA 5 has discontinued. As the developer of the antenna analyzers I am happy to comment the current situation. The exclusive

Re: FA-VA5 sold out?
Hi, I am just on vacation in south Europe with very limited network access. I will comment the current situation the week after next week. Regards Michael? DG5MK

Re: FA-VA5 sold out?
Since the discontinued notice is on the official page, it seems a legitamate notice. They also say the official support page will continue, so that is good news. -- VY 73, Wes WB7BR

Re: FA-VA5 sold out?
I read on the SDR-Kits website that the FA-VA5 has been discontinued. Perhaps someone can confirm this. This group will continue, however. 73 Dieter, VK3FFB

FA-VA5 sold out?
The FA-VA5 currently lists as "sold out". Will there be another batch? Are there other developments? 73, Geert Jan PE1HZG

Re: LCR inductance measurement and determination of the coil-capacitance
Hi I found that a coil with a relatively small winding capacitance may not be accurately measured with the proposed method above. For a 3.9 uH coil with a diameter of 27.5mm, wire diam. 1.5mm and

"Why not just post them in the Files section of this group?" Would be a good idea for those of us who absolutely refuse anything and everything google related! Just sayin'...

Re: LCR inductance measurement and determination of the coil-capacitance
Thanks Dieter, I accessed and downloaded the file FB. I think I have figured out the procedure, and played with it a bit. Fine bit of work, thank you for taking the time to build this spreadsheet.

Good to see some interest in the subject. Four members have requested access to the Google spreadsheet which I granted. Presumably, the direct link requires to have a Google account. I can provide

LCR inductance measurement and determination of the coil-capacitance
Hi Recently I wound a cylindrical air-coil of about 15 uH for a loaded antenna. I used stranded electrical wire with plastic insulation. Clearly, the insulation helps in making all windings nice and

Re: Calibration Question
Hello Hans did you do a "master calibration" as described on page-12 of the manual ? The data of the "current calibration" on page 11 is lost when the unit is switched off (page 11, last par). This

Calibration Question
Hello all, I need some assistance with the calibration process as I am obviously doing it wrong. A 25 Ohm pure resistive load shows an SWR of 2.7 I have a set of open/short/ 50 Ohm calibration loads
