80 meter CW net

Charles W. Powell
 

Well the 80 meter net was something of a surprise. I had a lull in the storms and after hearing Bill KV6Z so well on 40, I thought I would give NCS a try on 80. I must admit though the QRN was vicious.

Checkins:

WD0WF - Jim, MO
KV6Z - Bill, OK
WB0CFF - Carl, MN

NCS - NK8O - Chas, KS

40m Net

Got a break in the weather and had a pretty good net tonight even with pretty bad QRN.
Got some close-in stations tonight that I haven't heard for a while.
QNIs were:

WA0ITP     Terry       IA
KL7IXI        Mike       MO
NK8O        Chas       KS
K0BXB       Martin     WI
KK5IB        Darryl     AR
KD0WF     Jim          MO
K4KRW     Richard   NC
KV6Z         Bill           OK (NCS)

Thanks everybody

Dear All,

Just finished reading some of this evening's 4SQRP 40 Net mail thanks to ...

http://wildcatsdr.com:8901/ 
located in Georgetown, KY. 

I tuned in between from 8:30PM to 8:45PM your time.

Solid copy KV6Z, KD9WF, and K5XRW. 

Quite the thrill for me I must say!

We’re having some thunder and light rain in Lebo, so I’m not connecting the tower for the 80 meter Net tonight.

You guys jump on if you can and have fun.

Hi everybody,
I'll do my best to hold the 40m net tonight but it would be good if someone else was on standby for NCS.
We are expecting more storms tonight, and after what happened last night I'm going to err on the side of caution.
I was standing in my garage after the storms had apparently cleared when a lightning bolt hit my neighbor's house.
That bright bolt and the crack and the smoke and the sparks were a frightening sight. It took out almost everything electronic in his house. I think my pacemaker skipped a beat and glad my defibrillator didn't go off. I hope to hear you tonight but if it's stormy, I'll see you next week.

I hope your coax was NOT connected to any of your radios, because with a close strike there is such a current surge or "sympathetic" strike that you could have damage too. Take it from an old commercial radio serviceman, I have seen it happen. My antennas are disconnected and grounded until I use them!!!  Russ   K3NLT

Ken,

PS...I need to get back with the 4 State QRP gang and maybe have them host these files on their web site.

Thanks Jim

You nailed it. That transistor had a short. Tested it with my Peak semiconductor tester. I stuck in another one. Now it toots quite well.

I am working to put together a Kortge transceiver using your class e tx, your rx, your audio filter and your variable xo, all linked with your magic box.

Your designs and manuals are great. Hope you will make more.

Thanks for the kind words Ken.  I'm getting too long in the tooth to do many more designs.  By the way, I have designed 3D printed cases for the MagicBox and SS-40 Rx/Tx combo if you have a way of printing them; you have a printer, local library has one, your UPS store has one etc.

Glad you found the defective transistor.  That is a rare failure; almost never happens with bipolar transistors.

72 and be well,

Jim, K8IQY

Thoughts on the NM0S Hi Pass Filter

WA0ITP
 

NM0S has provided a very nice Hi Pass Filter Kit, http://www.4sqrp.com/4S-HPF.php, for 4SQRP to include in it's stable of kits. It is the same form factor as his earlier low pass filter, and there are no toroids to wind. Spiral coils on the pcb provide the needed inductance. IMHO this nice little filter hasn't received the attention that it deserves.

Why a Hi Pass?
Anyone using  a direct conversion receiver probably need one to prevent overload from local AM broadcast stations, unless that rcvr has a built in HPF.

My QTH is abt two miles from two kilowatt BCB stations, 1240kc and 1480 kc, and they have been a problem for every direct conversion receiver I've ever built - homebrew or commercial. Several years ago I added a very simple HPF to a project and it helped but didnt do the job completely.  So I added caps in series with the shunt inductors, to trap the BCB signals and that worked fb.

While my version is ok, Dave's rendition is superior (to be expected), and the kit's pcbs make it extremely easy to build and it looks great in it's case.  If you have an offending BCB station or two, make them disappear by changing C4 and C5 so as to make two series resonant traps.  There is a nice calculator here http://www.pronine.ca/lcf.htm

Attached are schematics and performance graphs for your review, all are screenshots from Tonnesoft's very excellent filter design program LC.  Thanks you Jim for a fantastic program and your willingness to share a free version.

Observe the awesome attenuation Dave's design has right off the bat. 1M attenuation is -96db!!!  My measly effort only attenuates 1Mc 36 dB..

If you need to use a high pass filter, the NM0S/4SQRP will do the job, and can't be beat for simplicity and effectiveness. http://www.4sqrp.com/4S-HPF.php  I just bought one !

This Saturday musing is brought to you buy the weather, is raining and cold here.  Questions and comments are welcome.
