Hi folks. Just a quick question, but I found a small AM/FM radio here (50p!) with a tiny ferrite rod. Wonder what it uses to set the frequency for AM range? Surely not a tuning diode like MV1404 as these are incredibly expen$ive. Was wondering about pulling the rod and modifying it for WWVB as my existing radio clock works and it would be a shame to mess that up. Should be easy enough as I have (somewhere!) a working LCR meter so can wind a suitable winding over the existing one if its too far off or simply add a couple of layers of Litz wire to approximate the required 65 kHz WWVB. I'd also need to locate a 65 kHz quartz crystal for the XT2 position. External antenna might be better here as it would be very weak indeed being from the USA but there's a couple of methods I can use to improve this like using an optical relay from multiple locations at equidistant points. thanks! Andre

But if you do want to mix both the REF and DUT channels, wouldn't it be better to use a single source to drive both mixers? > > John > ---- > > On 10/17/20 8:59 AM, Gerhard Hoffmann wrote: >> I'm trying to make a quick frequency extender for a timepod. >> MCL PSC2-1 power divider, 2* SRA-1 7 dBm ring mixer, 2 DIL 80 >> MHz-oscillators _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
