This sale is for an optional filter board for
the NRD-515 receiver outfitted with two filters. This filter board and
filters are no longer available and is desirable for your NRD-515 if
you desire to enjoy additional bandwidths with your classic JRC.
This filter board is somewhat unique as one
filter is installed on the backside of the board. We have never seen this, but we also have
never enjoyed a wider AM bandwidth on this board. Please note that the board appears a bit
messy with regards to filter installation. But it works perfectly and the board is out of
sight once installed.
We have sold a number of these daughter boards
over the years, but most often they have on CW or SSB filters installed. This daughter board has a Murata filter for
the wider SSB 2.7/3.2 (6 dB and 60dB signals) and what appears to be a black filter
attached on the backside of the board offering bandwidths approximating 8/10
KHz (8 for the 6 dB strength signals and 10 for the strong 60 db signals).
This combination of filters compliments the
stock filters in the NRD-515. Thus you
would have:
2.4 KHz (stock)
2.7 KHz (optional)
6.0 KHz (stock)
8.0 KHz (optional)
The 515 receiver enables you to utilize IF
filters in other modes. Thus, you can
use the 2.4 and 2.7 filters in AM mode, and using the passband tuning, actually
get decent audio while filtering out potential side channel interference. Or with the 8 KHz filter, get much fuller
range audio for enjoying program listening in AM mode. With strong signals (60 dB), the 8 KHz
bandwidth actually is more like a 10 KHz filter bandwidth.
To install, you merely remove the 4 screws
holding the top cover in place, plug in this filter board, and then refasten
the cover. Total installation time should be about 5 minutes and does not
require any soldering or technical skills.
