[R-390] Mechanical Filters and "A" (was Hi)

Cecil,

I have one R1051A front panel. It looks like a B but with an A tag. Haven't
a manual for either so can't say if ther are any difference between.

Own Montedel manuals for the following equipments.

SRT-100 Receiver transmitter set
CU-973/UR-N  antenna coupler
AM-3007/URT-N  RF amplifier (group = Receiver R-1051-A-URR; FSK conv-comp
SP-270; Exciter T-827-A-URT; RF amp. AM-300-URT-N & interconnecting unit
SP-363-A)
T-827A/URT Exciter
SP-263-N LF converter (for use with R1051A/URR receiver or similar, Extend
the frequency range of the R-1051A/URR down to 14 kc/s)

Perhaps Montedel was/is an European contractor for maintenace. Maybe some of
the Italians fellows, or the ones who spend some of their "tax-payed
vacations" in Italy, can say more about Montedel.

There must be E & F models because I own one manual for R-1051E (Navelex
0967-428-2010), one for the R-1051F (Navelex 0967-LP-617-7010) made by
Stewart-Warner Electronics (N00039-76-C-0297 15-Nov-1978) and the
Maintenance Standards Book for R-1051F (Navelex 0967-LP-617-7020).

Regards

Miguel
