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.

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.

Here in N Arkansas, we have been lucky here, disconnected all when i heard thunder coming in mid-morning. We were weeding beds and  planting our Tomato plants and added dirt to potato plants, was amazed we got it all done in a hurry, as day progressed checked out all and the new plantings are happy ,Whew ! So far no heavy activity only T-Storms bringing fresh clean water , a blessing . 73's and 2s, AJ

Yes It did keep my mind busy for a few hours.
Oh well, I am going to use the NVIS I just built, put up a Temporary vertical/p antenna, and Bert is going to drag out EFZ or the like this weekend.
Its all ok, just a opportunity to try something new!

A tornado went through just east of me ( about 40 miles ) and according to news reports 2 people were killed this afternoon. They were in far Northeast Oklahoma and it tracked on up in Kansas and I don't know about Missouri.

Very close to the Pittsburg / Joplin area, so I am praying everyone is okay and praying for those lost.

I understand the Quapaw , OK. , fire station was destroyed.

Terry, No, I don't know CW that well yet and that Ez Meyer sounds like a great idea. What does an ex keyer do? 73 Rob P.S. I am thr truck driver that contacted your right before OzarkCon asking for tips on learning CW.


Re: Good qrp kit for beginners

FB  Rob,

If you're new to Morse code, I'd suggest an EZKeyer II, It goes together well, is a finished kit when complete (enclosure comes with it), and its' sidetone will make good sending practice.

If you already know code, and have a receiver, then the NS-40 would indeed be a good starter kit.   Put a 7122 crystal in it.  7122 is the Four State hangout, and KC0PMH is NCS for a net there on Wednesday evenings.

Hope this helps, pse don't hesitate to post your questions

I have no experience doing SMT parts and very limited soldering experience. I think I'll do ok with through hole parts. I would like something a little more complicated to get me out of my comfort zone but maybe something simple would be wise. The NS-40 seems like a fairly simple kit. Thanks, Rob Rob Rob

I think if it were me, I would start off with the NS-40 just to get your feet wet, so to speak.  Can probably have that one built and operational with a couple hours of work.  Would be an excellent starter kit – in fact, it’s what I used for my first kit to learn how to solder!

The  4sqrp NS-40 is a CW tx only and you'll probably need the Magic Box switch to get the best out of it.  My experience is the Cyclone being the best choice, if you're a CW man.
