As the subject line says... I've built all these little 'goodies' so now what to do with them...

VFO's, Crystal oscillators, IF's, RF stages, detectors, audio amplifies, balanced mixers, etc etc...  Now what to build...

Well with the VFO that has a serious drift problem...  It's really not a VFO but more like a DFO (Drift-able Frequency Oscillator as the Timtron would call it) I could rig it up with a few of the other self-assemblies as a receiver and I would have a scanner...  good idea?

 Now with the really good sub-assemblies I want to build a receiver that not only can be used on short wave but can also be used to read the minds of those people that are plotting against me (how's that for a little paranoia for some added suspense?)

I really don't know how to build such a thing so I must call on someone much smarter than I...  (no not a garden slug... I can hear what you folks are saying so cut it out ehhhh?)  I must channel the spirit of Doctor Richard P. Feynman!!!!  That's the ticket... Doctor Feynman can figure this one out!!!

Here we go....  channelling Doctor Feynman, channelling Doctor Feynman, channelling Doctor Feynman, channelling the Doctor, channelling the Doctor, channelling the Doctor, ... make your Spirit known to me!!!!

<<<<Pooffity Poof de poof  slam bang thank you.... BANG!!!>

Well... all I got was what looks like an old fashioned 'out house' with a sign on it that says; 'Litter Box'....  hummmmm what good is this????  Ratts!!!

Wait... the Litter Box door is opening and... and...  <what the heck!!!>  It's Doctor Poo...  !!!  Doctor poo and his Litter Box...

This always happens to me... I start a useful project and it all turns to crap...

I'm outa here....

<Door slams and junk falls to the floor and it ends up look like a wire factory exploded>

(((SIGH!!!)))

/* when in doubt use an 'idiot loop'... problem solved.... */

10 M is open right now... 1800 UTC...  Lot's of contesters on... and now for my comment...

Maybe some of you might remember ( I don't know why you would but... I digress) in the past I have mentioned that there are times when 11 meters is wide open but 10 meters is 'dead'...

Here's my point, kinda-sorta,  I can only hear 1 (one) 10 meter CW beacon at my location today but loads of USB/CW real time stations...

I guess this means that 'human nature' is a factor...  If Joe Ham doesn't hear anyone on the band then the band must be 'totally dead'.

But today, for me at least, proves otherwise...  I always call CQ even on those days when no one is on (but if I am on then there IS at least one person to talk to...)

Makes me think about a guy many years ago (on 75 meters daytime) who used to carry on a 2-way conversation with himself... and at times he would really get angry about what he said and then give himself the devil for saying it...  I really enjoyed listening to him... (I  withhold his name and call as he has since pass on... may he resume his QSO with himself where ever Hams go when they go SK)

Good Grief I'm rambling again... sri me bad...

Try 'The AM Window'

http://www.amwindow.org/index.htm

Make sure you check out this series modulated rig that uses 6AQ5's ... QRP but you can modify it for a pair of 807's, 6146... etc

http://www.amwindow.org/tech/htm/series.htm

This rig can put out very high percentages of modulation without distortion... feed it clean audio in and you get clean audio out..  I've heard these on the air and I consider them the best for those that don't want to pay big bux for a modulation transformer.

Signal of NCS S7 most other stations at the noise level

As with most area nets these will last 1 hour but may not transmitter for the entire hour, stations will remain on the frequency until closing at 2359 UTC.  NCS will close the net at 2359 UTC

General Radio Discussion / UNEXPECTED GEOMAGNETIC STORM
« on: January 07, 2015, 1545 UTC »
A G2-class geomagnetic storm erupted during the early hours of Jan. 7th, sparking bright auroras around the Arctic Circle. What happened? The interplanetary magnetic field (IMF) near Earth tipped south, opening a crack in our planet's magnetosphere. Solar wind poured in to fuel the storm

Audio:

Spec:

I've added this one because the audio was great because I got a number of different pulse rates on this single frequency with a low noise level.

In Filipino (Tagalog) language.  Good signal S7+  with slight atmospheric noise

The YL likes it when I can receive broadcasts in her native language :-)  Makes my trips to the radio room more acceptable ;-) <heh>
