[Milsurplus] [Boatanchors] CU-872A/U antenna coupler FS near Boston

[Francesco Ledda]

Also, the CU-1099/FRR is 70 ohm. It was used with receivers with Z 50 ohm.  Wonder why....

And i always wondered if the antenna connector was a 75 ohm N connector or the standard 50 ohm. (The difference is that the male center pin is thicker on the 50 ohm version, and will damage a 75 ohm female part)

>> Greetings,
>> This is working, some "test" readings are a bit on the low side so perhaps some of the 6922 tubes are getting tired.  There is some glue residue below the normal data tag most likely from some other data tag that was mounted there.  Looking for a local sale in the Metrowest or North Shore Boston (This of course means that the first reply will come from Alaska!).  I'm not really interested in shipping this or dealing with Paypal any more in MA.  Any interest?  I could bring it to the Lewiston ME, Nashua, NH, or Framingham, MA fleas.  Nearfest as well but I hope it finds a home sooner than May!
