(2) Shared FRS and GMRS simplex; GMRS repeater output. (3) GMRS repeater input. The output frequency of this repeater input is the input frequency minus 5 MHz. (4) FRS transmissions are limited to bandwidth of 11 kHz with a transmitter deviation of +/- 2.5 kHz. Channels are on 12.5 kHz centers. (5) GMRS transmissions may have a bandwidth of 16 ...
One group advocating the construction of home-brewed D-STAR repeaters is Free-Star. Free-Star is an experimental approach to the implementation of a vendor neutral, and open source, digital communication network for amateur radio. [22] GB7LF in Lancaster, UK, went live in May 2009 and was a converted Tait repeater.

In some repeater systems, the time lag can be significant. The lower tone may cause one or two syllables to be clipped before the receiver audio is unmuted (is heard). This is because receivers are decoding in a chain. The repeater receiver must first sense the carrier signal on the input, then decode the CTCSS tone.

An SSTV repeater is an amateur radio repeater station that relays slow-scan television signals. A typical SSTV repeater is equipped with a HF or VHF transceiver and a computer with a sound card, which serves as a demodulator/modulator of SSTV signals. SSTV repeaters are used by amateur radio operators for exchanging pictures.
The IRLP software cannot decode the D digit (the bottom right key on a 16-button DTMF dial). This is a limitation of the hardware in the decoder. DTMF digit D is logic level 0 on all 4 bits from the MT8870. Thus, the parallel port pins would all be at 0 volts, which IRLP regards as no DTMF digit present.
