I have an extra Efratom model FRK Rubidium Frequency Standard, serial#
250/2140. Provides a very stable, accurate 10 MHz output. The unit
requires a 24-28 volt regulated power supply at approximately 2.0 amps. I
will provide a suitable supply with this one. These units are usually pulls
from Omega Navigation receivers. Since the Omega system was
de-commissioned, some of these have found their way into ham circles. They
sell around $300-400 bare with no power supplies and no RF cable. It has a
funny little coax connector on the unit, and I will also provide several
matching cables to make life easier for the lucky person that gets this one.
I would like $325 cash, check, money order or PayPal for this one and I'll
pay the shipping anywhere in the US only. I will not ship this overseas or
to Canada as it's US Military Surplus and I don't know the legalities of
shipping it out of the States.
I will also trade even for an MFJ-989D or an MFJ-986 Tuner. Either tuner
would be okay. I'll pay shipping on the standard, you pay shipping on the
tuner.
Please, reply off list if you are interested - an older Dentron MT-3000
tuner would also be considered for trade.
