Hallo Rolf,
nach dem Datenblatt des USB3320 hat der einen integrierten ESD Schutz, braucht also keinen externen. Vielleicht ist der auch defekt.

Hi Andreas,
do you use a 20 W amplifier or a 43 dBm amplifier?
Once I've used a 88 dBm amplifier on 1 000 kHz.

Hi Thomas,
I think we use mixed units of measurement: dB for amplification and attenuation and W for the power.

Hi,
you can use a directional coupler (eBay about € 15.-) and a crystal detector:
N-Typ HF-Koaxial-Richtkoppler, Weiblich, 200W, 800-2500 MHz, 5 DB ~ 40 DB, 50Ohm

Don't forget, Analog Devices produces also the Pluto.
PE1CMO's price list is in the brochure, but no address! Very strange. I had no problems getting my 20 W amplifier from René.

Hi Matthias,
my 20 W amplifier from PE1CMO is full duplex.

Hi there,
I miss the 1 W amplifier from AD CN0417 and the 20 W amplifier from PE1CMO.

Danke Matthias,
da ich noch analog sende, werde ich erst einmal die PTT-Lösung wählen.
Viele Grüße,

Wie realisiere ich denn eine Rückhördämpfung, um mich selbst leiser zu hören als die Gegenstelle?

Hi,
I don't know if SATSAGEN is a reliable analyzer. If you switch 10 dB in between, all lines must decrease by 10 dB.
I have to finish my clock generator and measure with a HP Spectrum Analyzer.

I suppose dxpatrol adjusts the capacitor for best swr
