You maybe knowing your microwave's inner workings. It uses a microwave valve which consists of LC chambers of 2.4 GHz. And they are excited with a dc hv of must be 50 Hz. Now we have two possibilities, the output is in trains or constant rf output. Who of the hams here can messure that output ?... more »

EMI prevention / protection?
|
| |
I'm using the wein bridge to generate audio tones that are fed to the transmitter for digital radio communication (basically a homebrew ASK radio modem). I'd be open to using that, but I'm not aware of any radio modems that output square waves. This oscillator also has 2 digital pots attached: 1 to trim the space... more »

osc coil
|
| |
Anyone know where I can get a CA-5484 (that's a manufacture part no. not Realistic I think it says matsumi on the top of the can)osc coil from a Realistic DX100 receiver it's 1.6-4.5 MHZ it looks like the old 6 transistor radio can transformer.

ADC-40 FI ? (KD1JV QRP)
|
| |
HI, I'm building the ADC-40 made by KD1JV. I would like to know what kind of 10.7 FI is used as filter because there are several type of FI with different characteristics spotted by different color. Could someone tell me the color I need ? Thanks a lot. Here the link of ADC-40 : [link]... more »
