Borja, I have Wellbrook loops in use but none of them do a good job on vhf and of course not uhf. What type do you use? I had a ALA1530 which went defective...
Thanks Mike. Sorry to be paranoid only a link preceded by a one liner like: "this is awesome" or "this is interesting" makes me suspicious. On another forum I ...
Do you wanna use duoplex?? So receiving with fcd (say on 70cm) while you transmit on other band?? Then you need a separate filter setup ... If semi duplex is...
Hi Sigi, Hi Steve, you're both right. On a HF contest I like to hear on one side of the headphone the DX station and on the other side the split frequency, so...
... Don't worry James, these frequencies and those far higher have been in use by various services for 60 years or more. If there was any evidence of cancer's...
... Yes, and so many other things... Radars used on ships tend to use a frequency around 10 GHz. Recreational boats can reach 2.2 KW, and commercial vessels 45...
As regards the power company "refusing"; to tell people which mesh nodes are acting as routers- this is because they don't know. That's how meshes work. They...

A perfect task for your Funcube Dongle. If you live in Victoria you probably know that all electricity meters in the state are being changed from the...
I have had my Wimo supplied HF converter for a week now and it works great! The Wimo HF Converter is very well made, The PCB has mounting pads on both sides of...
Hello steven The subject says converter ideas ... so I think he wanted to receive shortwave with the fcd Fullduplex 2m 70cm is another story ... But that also...
Sigi, I believe Marco's goal is a full-duplex satellite transceiver using the FCD as the receiver and his FT-847 as the transmitter. The FCD will still be...

I know that you can do it (but did not try yet) It is before the pa section (all is low power signals so when txing nothing should happen) You grab the first...

I think I measured 140mV with a bit less than 5V. This is almost 700mw, quite a lot of power even though I don't remember well. It is very easy to check,...
