Re: Question about 13 cm. converter



Bill,

Yes, you can use the two converters together. This sort of thing is done all
the time by  regular terrestrial microwavers with good results.

If, for example your 2m-to-10m conv. converts 144.000 to 28.000 and your
2.4Ghz conv converts 2400.000 to 144.000, then together they will convert
2400.000 to 28.000Mhz. So if your IF radio tunes 28 to 30 Mhz then your
going to be tuning 2400 to 2402Mhz.

This is so if both converters are using the usual "low-side" injection,
which is usually the case but sometimes "high-side" injection is used. I'm
sure your Hamtronics unit is the standard "low-side" injection. And I know
that the DEM unit is also "low-side" as well. Should work great.

Are you planning to run a pre-amp ahead of the 2.4Ghz converter?

Good Luck on 2.4!
