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.
