[R-390] R-390A On 160 Meters

[wb5uom at hughes.net]

Good reading Bill ! Thanks
This morning at 6am Central, I was listening on 6.676Mhz to the VOLMET
Broadcasts .
 All Receivers are fed thru a DA-4 Multicoupler. The Rcvrs are : R-390,
Mckay Dymek DR-22, Drake R8-B, Racal  8217
When Honolulu was broadcasting, all 4 Radios were receiving it fairly well,
when Toyko came on
it was readable on the R-390, the DR-22 was really in the dirt, and the
Drake was having a tough time as well. and  The 8217 was all noise

I love this hobby.

> I had an experience over the weekend that I thought I would share with the
group.  I have a fine EAC R-390A from the 1967 production run that I
purchased from Bill Neill a few years ago.  I have never performed an
alignment on the radio, but have spot checked the sensitivity on various
bands of interest with an HP 8640B and the sensitivity appears to meet or
exceed the specifications everywhere I checked.  While listening to the K5D
DXpedition on 160 meter CW this weekend, I found that my R-390A could hear
K5D when my FT-920 transceiver and my NRD-525 receiver could not.  At the
time, all three were sharing the same antenna via a Stridsberg MCA104
receiver multicoupler.  While I have made this type of comparison a number
of times in the past, this is the first time in my experience that my R-390A
has clearly outperformed the receiver in the FT-920.  My FT-920 has an
excellent receiver and always outperformed my NRD-525.  I made the same
comparison between the FT-920 and the R
>  -390A on 12 meters yesterday afternoon, and the FT-920 may have had a
slight edge there, but it wasn't as dramatic as the 160 meter comparison.  I
realize that the alignment on the R-390A is a band by band issue, and
looking back at my notes, I don't see that I have ever checked the
sensitivity on 12 meters.
