The boards you have shipped recently, do they have the latest firmware?
If not, do we need some equipment and special software to upgrade?

Merry Xmass!

Hello.

Next two Ody went to Fremont (California) and State of New-York.


Please be very carefull with 1 Watt output driver, don't try turn on PTT when connector is in air.

If you don't use TX mode switch off 1Watt driver by button UP on your hand mic.

Best regards,

David

Is it a matter of over heating or an electrical burnout due to high VSWR?

Happy new Year!

Hello, Neoklis

Due to high VSWR could be burned the driver, FPGA and other chip. 

I will experiment with this later.

Best regards,

David

Hello, Neoklis

I ran a stress test and found out that it was impossible to burn the transistors due to an unconnected load.

The maximum voltage on the drain will be only 22 Volts peak but the maximum allowable voltage 40 Volts.

Be calm, it's reliable.

David.

Thank you for that David. I is also possible to use a 3dB attenuator to present a permanent
load to the output but a more sensitive PA will be needed.

>Be calm, it's reliable.
I am trying to be calm but my stomach is very upset - new year party! Lots of Cyprus wine...

happy new year all.

Suffered from a bad bug over the holidays, wished it was Cyprus wine.
Missed the St.Panteleimon and Commandaria St. John.

Hoping to visit again soon.

Enjoyed my 3 years there as ZC4AB (1966 - 1969) and many other visits since.
Happy New Year!
73 ... Sid.

Things have been getting progressively worse here, but St.Panteleimon
and Commandaria St. John (and others) are still as good! ;-)

We have had no news from Cyprus after the 2008 financial crash.
Guess the Keo and other stuff will still be the same.
Even the Coccinelli had improved over the 1960's vintage.
