Re: SS40

Ok so the combination of the SS40 and the NS 40 is now called SS40RXTX??? I assume that the Magic Box handles RxTx changeover. Those this also include the sAVO module?

Nice signal Terry, 
clean keying and not hard at all... very nice.
Band is a bit noisy tho... with the wind here and the storms way over there.... 
Hope it gets quieter for this weekend.. (7QP)

Have a great day,

I would love to have a QSO, but my antennas are disconnected due to a little lightening in the area.

I would like some information on the SS-40 transmitter.  I could only find PDFs for the receiver on the 4sqrp site.  Is it a single-frequency rig?

Tom

Good Morning Wxrpt

Dale Putnam
 

Good Morning, 
  The wind has been getting with it the last 24 hours, with gust to 50 - 60... and every once in a while..
there is a dusting of snow.. causes whiteouts while driving, makes for interesting situations, for sure.
My hopes are that everyone is ok, after yesterdays severe weather, that this wind will blow it outta the way, 
so this weekend, we can have a pretty weekend. (and I can be logging a lot of stations in the 7QP contest this weekend, on cw)
Today, the snow flurries are continuing with my horse feed buckets blown clear across the corrals, the feed troughs stayed put. 
Not loose dust around here now... with gusts to 60, I'm not seeing a lot of static buildup... yet. 
Did get a 1/2 inch of snow.. measured horizontally ... that would be 1/2 inch deep... on the vertical sides of the buildings and fence posts. The temps are nice tho.. at 31F.. the wind chill isn't too bad. Visibility is anything between 50 miles.. or 50 feet. depends on if 
there is snow or not. 

Praying all are safe, and continue to be safe, 

Have a great day,

Re: MC1349 IF amp

Donald Kelly
 

Hi Phil,

 

The MC1350P is an 8 pin DIP IF Amp. I think you are remembering the MC1496 mixer.

 

I like the MC1350P because of the ease of gain control for QSK.

 

It actually dates back to the 70’s maybe even the late 60’s. Wes Hayward used it in some early solid state receivers in “Solid State Design for the Radio Amateur”.

He also uses it in the updated book “Experimental Methods in RF Design”. The MC 1496G mixer was also shown in several circuits in SSDRA.

 

The K2 used the MC1350P as an IF amp.

 

The MC1350P has been called a noisy IF amp but its noise characteristics were considered to be offset by the fairly straightforward ability to implement gain control.

 

It is a great IF amp IC for moderate to intermediate level receivers. Not foolproof….but close.

 

One of my favorite parts guys, W8DIZ, sells the MC1349 as a comparable IC to the MC1350P.

Hi John,

I'm not expert but I suspect/(and see) that some folks have crossed over and are using current-feedback ICs for IF strips. One example of that
can be found by looking at the schematic for the SS-40 kit on the 4sqrp website.

My memory may be wrong, but I think the MC1349 came before the many 602 mixer ICs. All of these use Gilbert cells (4-quadrant multiplication)
to generat the frequency shift needed to get from RF to IF.

The ham radio handbook has some excellent chapters summarizing the evolution of these mixers. My copy is from 2004.

Good luck and have fun!

Thanks for the warning. 

Even my 225' Long Wire has picked up enough EMP to burn up my antenna tuner. 

Now, all are grounded, disconnected !

Patsy and I were driving out to our daughter’s house, she lives SW of Pittsburg when both our cell phones started going crazy. We both began scanning the sky, we are both ex storm watchers from NW OK. It all looked ok to us but I commented that a tornado could easily be rain wrapped to our south. Sure enough the one that took Quapaw’s firehouse must of been in there hidden from our sight by heavy rain.

Sorry to hear of the deaths in OK. Even with all the early warning systems we have today not everyone gets the word.
