How do you define the best transceiver ?
Hi,
Survey : what do you consider as an excellent transceiver from a pure technical side ? I don't need that you answer me, "the RTX that suites your need, guy". I 'd like a more technical opinion, taking in account the worst traffic conditions. If you like, can you give me your opinion, some clues, or even links developing this question (NB. I haven't got QEX that could probably help). IMHO, and very shortened, after the TX module, the RX is the most important module of un transCV (obvious). The TX module of a transCV is quite easy to build with few component and it has even not to be powerful (QRP). But the receive module is by far more complex. If a TX helps you to send your signal to the antenna, you need also an excellent RX to be able to listen to your contact whatever the conditions. Without speaking of the sensitivity (that I haven't discussed, looks obvious too), an excellent receive module should thus offer a great selectivity to remove or reduce noise and RFI and be active before the signal reaches the detection with the less amplification as possible (using filters like high/low cut, attn, rf gain, dsp slope, etc), excellent DSP filtering on IF stages, and all parameters accessible in "direct access" on the front panel instead of having to set these hundreds of values in sub-menus. Of course you pay for it, but my question is purely technique. Your answer will help me to complete an article I wrote about it, in which the selectivity has still to be developed (see later at http://www.astrosurf.com/lombry/qsl-transceiver.htm) Thanks for your comments.
