Have you tried to build in a PC inside the transmitter
instead of building a transmitter inside the PC ...?

Hi Marko,

I have earlier signed up for your newsletter
and now wonder how often they are mailed?
Have not seen anyone posted yet!?

Is it your sister ... ?

Schematics for The Grenade Transmitter and a PCB-layout!

Thanks!

Edit by PCS: Nice try, R_QRP

*LOL* Not me! Someone else is working on it!

Great job Marko!
The AM MAX II DSP looks very nice!

Care of your IRF-510 MOSFET's
MOSFETs are susceptible to electrostatic discharge damage (ESD). It is important to use proper grounding techniques while handling the amp circuit board and the MOSFETs in particular. While working with MOSFETs you should wear a grounding strap and have an antistatic ...

This is the most frequent question, and many newbies want a simple answer. There is no simple answer. The distance at which your signal can be heard will vary from listener to listener, depending on their equipment and location. In fact, many elements affect your range:

* the transmitter power ...

Using a series transistor as a class-A modulator works well in some respects eg excellent frequency response, but if you halve the standing voltage to the final to 6 volts and do nothing else, the output power will drop to a quarter. If you re-design the output match to produce the original power ...

For a 5-15 watt transmitter, the IRF510 is a pretty good choice.
Its Drain-source breakdown voltage is 100V, which gives a reasonable amount of headroom. On mod peaks the supply voltage will be 24V , assuming a 12V power source. The RF voltage on the FET will be something more than 2 times that, say ...

But we can't say the word again. Bad things happen when you say it.
And so it goes again and again and again.... LOL

May be for comming LPAM projects !?

This knowledgeable guy or company seem to be active everywhere with comments.
Anybody who knows from where he operates and how to get in contact with this guy?

Why not try this one for SW AM QRP:

What do you think now?

Garifuna culture is getting more respect and understanding, as Belize radio stations and clubs play punta rock, a blend of Garifuna lyrics and
calypso-style rhythms. Punta is an invention of the 1980s, but its origin goes back to the call-and-response pattern of earlier African music and to the ...
