One is marked as: FILTER BAND PASS 5915-99-920-1117 500 C/S TX & RX The other one: FILTER BAND PASS 5915-99-920-1118 700 C/S TX & RX Dimensions about 8cm cube and with a DB-9 male connector fitted on top. As they are painted in the well known RACAL RA-17 green I suppose they are RACAL origin. I have measured the B/W and it's about 180Hz by 6dB when connected to 600R. Anyone in the group who knows more about this specimen? Best regards, Guido, ON6RL.
