Also heard what sounded like a "whisky foxtrot" calling, but I'm not sure.


Some were better and some were worse than the 6:30 net.

Monday Late Net (7:30pm)

Jeremy Utley
 

Good turnout for the late net tonite. Jim, KC0DD, was a great help in
catching some relaying stations on this one - think the band had
definately "gone long" at this point!

KC0DD - Jim - Drakesville, IA
KA0NCR - Arnie - Fremont, NE
W8BVI - Glenn - Cedarville, OH (relay via KC0DD)
N2UHC - Tom - St. Paul, KS (relay via KC0DD)

Not surprised I couldn't hear Tom - he's only about 30-40 miles away
from me as the crow flies.

I think signals were a little weaker here on the late net tonite, so
the early one might be better for signal strengths. Definately also
think having people relaying is a good thing - maybe even have someone
else try calling for checkins too. I'll keep doing the early and late
nets for a few more weeks and see how it goes.

Monday Early Net (6:30pm)

Jeremy Utley
 

Here are the results from the early (6:30pm) sideband net. Signals
were a lot better for me tonite - still have the S9 hash that I always
have here, but I was hearing people pretty clearly on this one!

KC0DD - Jim - Drakesville, IA
KA0NCR - Arnie - Fremont, NE
N0TGR - Dick - Augusta, KS

Arnie also indicated that my new "wahr" is doing a lot better. I
started off with my 920 set at around 30W at the start of the net, and
bunped it up to 100W at the very end. Thanks also to Arnie for the
relay help with Dick's checkin!

Re: Miniature Baluns

Myron WVØH <s9plus@...>
 

I think so, the data sheet claims 350-W but I would hesitate at that power level. You have to be sure that your load is resistive or nearly so. Any reactance will cause increased loss and thus power dissipation the balun and heat up. If you had two of the same kind you could attach two back to back and test with a 100-W HF transceiver and a dummy load. I use a hand held IR thermometer to check for hot spots. I've wound some 1:1/4:1 baluns on some BN-43-0202 cores and they are good to 100-W on HF, again, if they see a purely resistive load.

Monday Sideband Net

Jeremy Utley
 

The Four State QRP Sideband net meets every Monday night.  This week, I’m going to try something different – since there’s been evidence the last couple weeks that 40 is “going long” before the 7:30pm time, I’m going to try once at 6:30pm Central time, and again at 7:30pm Central time for this week.  Those of you who are able to do it, try to listen for both (even if you’re one of those types who doesn’t have a microphone, at least take a listen) and lets figure out which time works better!

 

NCS is WQ5RP, with Jeremy, NQ0M as control operator from Beautiful Downtown Iola, KS.

 

Frequency is 7.285 MHz, QSYing down as needed to avoid traffic.  Check QRPSpots or the reflector for the actual frequency of the net!

 

I’ll be trying out a new antenna this week.  I’ve taken my old Ultimax 100 (http://www.ultimax-antennas.com/) and replaced the standard 24ft wire with a 54ft radiator, and tied it thru some trees at about 10ft in height.  Ought to be a pretty good cloud-burner.

 

Hope to hear you guys tomorrow night!

Re: Radio Shack 300 ohm twinlead

Wayne Dillon
 

Hi Mike,
I used the radio shack product for several years to feed my big doublet, It was about 170 feet away so I had to splice 2 rolls, it worked great. Sam is quite correct about the WalMart stuff, it's real junk, I had the same issues and went back to RS 300 ohm twinlead. Now that the Big doublet is down (since January!) and I'm still using the indoor 1/2 size G5RV (yep, RS 300 Ohm twinlead for the stub section) until the spring when antenna farming will begin again in earnest.
$0.87 a roll, good deal!

Re: Radio Shack 300 ohm twinlead

Hello,

Watch the wire gauge. I bought some from Wal-Mart to extend the TV lead-in
wire into the next room during a living room re-model. It was so flimsy that
the two wires could barely hold it's own weight inside the living room with no
wind blowing on it. On at least two occasions it did break under it's own
weight!.

Re: grounding

Don Wilhelm <w3fpr@...>
 

Dave and all,

Yes, the perimeter ground wire is a good thing.  It should be on the outside, and should not have to be too deep (about 1 foot).  It is for lightning protection - a lightning surge can follow the wire instead of punching a hole in your foundation.   Lightning wants to travel in a straight line, so you should have a driven ground rod each place where the wire makes a significant turn.

All grounds *must* be connected to the utility entrance ground rod.  It is a NEC requirement and is intended to keep everything including your AC ground and telco ground at the same potential, or as nearly so as possible.

This is grounding for AC and lightning protection.  It is *not* an RF ground.  An RF ground is more of a concept than a physical ground.  Think of an RF Ground as places where the RF voltage is zero.  That will occur at the midpoint of a center fed dipole or between a vertical and its radials (whether in contact with Mother Earth or not).  That is why we need common mode chokes at antenna feedpoints to keep the RF radiation on the antenna where it should be instead of also appearing on the feedline and coming back down into the shack. 

RF will travel on a wire in the same manner as it will on an antenna, so think of the current in a ground wire that is 8 feet long - consider RF at 10 meters - the end of that wire connected to a ground rod will be at a low impedance, but at the shack end of that 8 foot wire, it will present a high impedance to 10 meter RF, and it will be quite ineffective as an RF ground at that frequency.  If your grounding goal is to keep RF out of the shack, that goal will not be met, you must take measures in the antenna field to keep RF out of the shack.

See the information in the Electrical Safety section of later ARRL Handbooks for verification of the grounding information I have given above and the K9YC RFI Tutorial http://www.audiosystemsgroup.com/RFI-Ham.pdf for information on RFI including good common mode chokes.

Re: Thursday Morning Net Redux

dekle <dekle@...>
 

Hi Charles,
 
Glad to hear you tried to check in this morning. I stumbled into it myself at about 8:20. No one was acting as net control and I was asked to do it. I called CQ 4S starting at 8:22 until I heard no more check-ins. I even slowed down and also asked for any QSP stations at the end. We didn't leave you out intentionally. I'm sorry we didn't get you in the log. A few comments other than RST, QTH, and Name don't really constitute a "ragchew". The net is informal. I hope your 80m antenna work went well.

I tuned in to the Thursday morning net at 8:10 CST.  Wasn't too sure what net procedures I was hearing (or not hearing).

At any rate, KK5IB, KV6Z and WØIX were 559/569 here in NJ.  I tried dropping my callsign a few times; also did "4SQRP de W2SH".  No luck. 

Thereafter it seemed pretty much rag chew time.  599 RSTs had already been universally exchanged.  I tried to join in, but I wasn't a member of the 599 club.  With each minute of daylight (remember I've got about 70 minutes more of that stuff than you guys), signals became weaker. 

Finally at 8:25 CST I pulled the QRT plug. 

Went outside to continue work on a new 80m antenna.

Good morning everybody.

Well, after I checked into the Sunrise Net on 7123 I scampered over to 7122 to see if there was any action. I called CQ and got Phil W0XI right away and we had a nice chat.Then I got a call from Bart W0IIT and he said that no one had called the net yet and suggested that I try it. So, against my better judgement, I gave it a shot running 5W on my KX3.

Here are the results:

1422z   W0IIT      Bart      Ks    579   ( The coldest at 16F.)
1431z   AA5CO   Bruce    Ok   599
1436z   W0XI       Phil       Ks   599
1438z   WN0I      Andy     Mo   559

Signals were unusually good this morning. I wish that was always the case.
Andy was a new 4S member for me and will go on my W25 list. Thanks Andy.
