Antenna Switch 1269 big interference
« on: 2021-10-29, 07:51:03 »
Hi, I just installed this 1269 switch and encountered these issues : when I feed the switch in the whole spectrum hf I have repetitive disorders, they are not generated by the power switching because I tried to power the 1269 through a 12 v battery. I use a shielded ftp cable. A note: the 1269 has never worked by feeding it in poe (jumper in correct position) that it is a defective product? has it happened to someone else? thanks and 73 ik4pkn
I attach two photos of the flexradio spectrum with 1269 powered photo below and photo above not powered

Hi I did several tests to eliminate the disturbances, finally I powered both the 1269 ant. switch that flexradio through batteries, connected all through a small switch (tplink 5 ports) to a battery-powered laptop. The result unfortunately is always negative, I continue to have the same disorders.... I also bought a lan network isolator filter (https://www.reichelt.com/de/en/network-isolator-for-galvanic-isolation-ttl-1502-0-15m-p251526.html?&trstct=pos_15&nbc=1) but without getting improvements.. I don't really know how to do it... :(

Have you tried to lower network speed to 10Mbit under IP settings Eth-type?
This helps on WebSwitch 1216H.

yes, I tried with a 10 Mb switch and the interference was reduced. lastly I removed the 1269 switch and now the frequency is finally clean.
Thanks for reading
