TS-990 SSB 2.4 KHz Roofing Filter Pulg and Play by IK8TNG

After careful and SERIOUS performance analysis, the OM really benefits from it demands the most from the radio.

In the 80-160 band, where the noise in the band is inherently high, the use of the optional roof brings real benefit on overall noise thanks to its lower bandwidth, furthermore you can use the optional RF-GAIN function which is otherwise inhibited.

In the bands from 40 to 12m the selectivity increases significantly. Even an ear inexperienced person notices.... if you make a QSO at 7,070 LSB go further and don't buy (NDCnote of the manufacturer).
