My F5K user manual specifies the level of the input signal, but not the type. 1. What is recommended Squarwave or Sinus? [Tim] Sinusoidal 2. What is the impedance of the F5K input? [Tim] 50 Ohms 3. Beside the F5K have a Flex-1500. What is the recommended way of hooking both Flex radios up at the same time? [Tim] A 10 MHz distribution amp with good isolation. See the 10-4 from DEMI http://www.downeastmicrowave.com/PDF/10-4pd.pdf 4. What are other users using for the 24V 2A PS? [Tim] TRC power supplies http://www.trcelectronics.com/24-volt-power-supplies-low-open-frame-3.shtml On the last item I was thinking of reworking a 12V PS with a voltage doubler. Wonder what others have done. [Tim] I thought about it, but decided on a separate 12v supply the 10 MHz distribution amp, controller board (http://openhpsdr.org/wiki/images/8/86/Rb-Normal_paper_20.10.09.pdf) and the fans I user to keep the enclosure at a (mostly) constant temp. I use a 24VDB bus for powering the LPRO-101 73, John ve3dvv _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
