Measured how much gain and output power a chinese RF power amplifier actually has.
It promises 1W and delivers about that much when saturated.
P1dB seems to be around +27dBm, which is not horrible.

Is an isolator overkill when measuring a Gunn diode oscillators output power?
Not even the frequency, just power.

The badly soldered .141 coax broke off one of the radio clubs test antennas. So I fixed it more proper with more appropriately sized coax.
Pigtail used was a random one from the radio clubs "SMA pigtails"-drawer.

Nice antennas with nice and flat gain too.

YES!
Band is not gone.
Not back to it's former glory. but not some evil joke like 25mW EIRP limit or something.
But still very usable.
And unlike now, I should not have to buy back the band in 25kHz chunks if I want to operate on it.
