GPSDO dual channel from Leo Bodnar how to configure?

look at this link:

http://www.leobodnar.com/shop/…duct_info&products_id=234

and then klic on "how to use"

the problem is that the second output could only be used when you can devide the higher output by an integer. That means 25MHz and 10MHz does not work, because the devide result is 2,5!! that is the reason Guntram

So when you use 50MHz and 10 MHz this works. so you need an external devider by 2.

DJ7AL Jürgen that does not work.. look to my posts above..

Hello,

I use 10MHz and 24MHz.

(when you have a LNB originally running with 25MHz your output is around 1129.600 - no problem for a SDR - and thus you can also use a normal SAT-TV-Receiver for wide band).

Thus for me it is a win - win situation. 10 and 24 MHz is a working QRG-combination and as bonus DATV

With the parameter shown in the picture below 25/10 worked for me.

Still searching for paramter set to use 40/25

I've contacted Leo Bodnar <problems@leobodnar.com> via mail and they gave me this for 10MHz / 25MHz within 1h:

I am also using 25MHz and 10MHz combination since many weeks without problems.

Now, I also tried to do 25MHz and 600MHz combinations, which also seems to work.

The reason is to use the 600MHz as LO for a passive minicircuts mixer and output the mixer to my 2m radio (and receive QO-100 then around 139 MHz, wich most 2m rigs cover without any problems).

The problem was that 25MHz and 595MHz (for direct RX on 144MHz) combination does not seem to be possible to configure,
