PA2MRX 2/70/23 station setup
In mast coax relay in use. ARS-BPR-1N. On TX isolation to other port is more then 80dB.
Another amateur measured these relays, I came to the same results using my SA.
Want more protection, just add another relay.
LNA protection using a extra SMA relay and 50Ω resistor in plug. When the system is not in use the
LNA will be disconnected from the antenna.
Software on the computer:
LNA`s are also homebrew and ready, made after plans from the internet using a ATF-54143
A nice page for EME beginners (like me). I also just started trying MS (meteor scatter)
