Indeed - what would be good would be a IC705 with just a few milliwatts output and fully duplex and full coverage. Just turn the dial to the received station, hit the ptt and be transceive, thats the goal If the the equipment is designed in a perfect way, the signals are as good as from a shortwave radio. The Adalm-Pluto is not an option either, because it needs a pc/laptop. What is the alternative? Two unsynchronised FT-817/818 ? The IC-9700 is not a realy good choice for field operation.
Which setup for (real) portable use do you prefer? It depends on the quality of your over all setup and a good working stabilisation.
We are in 2020 and not in 1950, so it should be no problem for a licensed ham to keep rx and tx on track without separate radios or the usage of a pc. There are provisions for a Pluto, TCXO RTL-Stick or just another analog receiver. There is no difference to a separate setup for rx/tx, because i have an option to monitor the feedback from the satellite at any time. I am always operating my transceivers in simplex mode, no matter of the capability of crossband operation. Sorry, I have taken the liberty of modifying the title a little bit On AO-40 the time delay was twice as much compared to QO-100 because of 60.000km apogee It's OK when you are just starting to get up on QO-100, but it should not become a standard and it should not be promoted as a good solution. and to completely depend on an internet connection to a WebSDR, is not what I think is good practice. In "portable" operation it does not help at all, if you don't have internet. We have discussed this here and elsewhere many times and the ignorance to rules given by the QO-100 Transponder Bandplan and Guidelines is sometimes disappointing. The other point is about simplex operation: it's a step back, in particular if you don't want to carry another computer with an SDR. So in this case the IC-705 is nothing special or new. I was not only thinking about QO-100, but also about portable QO-100 and LEO satellite operation.Ĭonclusion: The ICOM IC-705 is definitely NOT READY for Satellites. I know and trust that you are an experienced person and you know what you are doing. The waterfall display for transmission check can be achieved by the WEB-SDR or with a tablet with the SDR-Console / RTL-Stick which i have built in at my transverter. It is just a simplex transceiver, but i always use the same QRG stabilized by GPS for TX and RX, so there is no need for a satellite mode.
