[Elecraft] RE: 2 radios, 1 antenna... finally a prototype

[JEAN-FRANCOIS MENARD]

Actually, I found some limitations and security concerns. From my point of view, I can live with the securty concerns this way. But the main limitation I found last weekend is when you "split" signal source in 2 different output, you loose 3dB on both rigs when used on the same band, this is normal and already known.... and 4 output would be 6dB, and so on.

It does the "job" like this, for a first prototype, it is not too bad. :-)

I'm seriously looking and working on a new design that would now include two signals source routing. The input will be filtered and pre-amplified to regain only the 3dB lost; but no more gain. And when transmitting, using a different "direct path" to avoid the RX filter/pre-amp with relays switching.

It is not too hard, but must take a little time to figure it out the best way.

I let you know about more experiment later... ;-)

Best 73.
