Kenwood TS-990S Sub Receiver, Triple DSP, The sub-receiver incorporates the TS-590S receiver

HF/50MHz TRANSCEIVER TS-990S Sub receiver

An already legendary Sub-receiver supports dual reception.

Two attractive features of simultaneous reception on different bands are that you can easily check the condition on other bands and still easily handle split-operation.

Innovation spurred by digital technology has revolutionized the Kenwood sound.

Even after using narrow bandwidth filters for long periods of time, it is still easy to hear and less tiring to listen to.

In addition to introducing AGC control using dedicated DSP,

we have further refined the Kenwood sound and reception sound quality transmitted by radio operators worldwide by innovating the analog AGC unit

and installing numerous interference and noise elimination functions. Such innovations have given new life to Kenwood’s legendary sound.

Down-conversion occurs on the 160m/80m/40m/20m/15m bands*

The sub-receiver features performance that has exceeded its class since going on sale, thus further refining this popular receiver on the TS-590S. Be- cause this is particularly the case on the front end, where it employs circuit configuration that makes down-conversion possible on the leading five ama- teur bands, it can be used in actual operation despite being just a sub-receiver.

*The IF bandwidth for 160m/80m/40m/20m/15m bands is (SSB/CW/FSK/PSK) for frequency levels 2.7 kHz or below.

Roofing filters, 500 Hz, 2.7 kHz

Frequencies of 500 Hz and 2.7 kHz are standard for sub-receiver roofing filters. You can maintain a

more or less flat dynamic range even if interference impinges on your reception frequency, thanks to superior close-in dynamic range properties. You can clearly catch signals under conditions made prob- lematic by strong close-in interference signals.
