as OM Gert Nilsson wrote, the CFJ455K5 or CFJ455K4 could be the ones used in
the R 1000. Here are the values:

CFJ455K4
6 dB bandwidth: 2.7 kHz min
60dB bandwidth: 5.0 kHz max

The K5 is not listed, sorry, the values for the K6 are 2.0 / 4.0 kHz, and
for the K8 1.0 / 3.0 kHz. The K7 cannot be used, as it's center frequency is
453.5 instead of 455 kHz.

I owned a R 1000 about 22 years ago, and did some mods - filters,
attenuator, change of an FET...
No experience of my own with the Drake so far, so I cannot compare.

vy 73,
Willi
