Full Duplex Radios
by Sigil 03 Jun '09

03 Jun '09

Hi, I have been trying to follow this confusing discussion about "Full Duplex Radios". It seems to me that different people are using the same term to mean different things. Everyone seems to agree on the meaning of "Full Duplex" as the term is used when talking about Ham satellites and radios. It is a radio that allows you to listen on one frequency in a particular band, while simultaneously transmitting on another frequency in different band. However, the phrase "Cross Band Repeater Mode" seems to have two meanings as it is being used on this reflector right now. Meaning One: a radio the can be used with a cross band repeater somewhere. That is, a radio that can be set up to receive in one band, but switches to another band when the PTT is operated and the radio transmits. When this radio transmits, the receiver is turned off. Meaning Two: a radio that can be configured to function as a repeater in that it retransmits the received signals in a different band. Naturally, it does this simultaneously. It is a Full Duplex Radio. Most (all?) modern HF radios can do "Meaning One" (A/B VFOs, etc), as can many dual band UHF/VHF radios, so this is perhaps not particularly unusual. It might be better to reserve the term for those radios that can function as a repeater. Sil - ZL2CIA.

>> ... Yaesu FT-8800 ... Really? Dual-receive, indeed. And will perform crossband repeating. But I can transmit on one band and simultaneously hear myself on another with a FT-8800?

Re; Full duplex: same band ?

Hi Nigel > Full Duplex can be both receive and transmit simultaneously > in the same band or on the same frequency. There will be very few radios I guess that can at the same time receive as well as transmit on the same band / frequency ... At least my THD7 and TS2000 can do full duplex, but not on the same band. However I guess it's a grammar thing, as I do not see an application for such either :-) Henk, PA3GUO (still like my TS-2000 a lot, many years after buying it, it still can do whatever I like these days: eg. look at http://www.vimeo.com/4911267)
