Reminder for tmrrw morning's net. 7122 at 8:30 Central.

Due to the big signals heard on the Sunrise Net in 7123, I'll probably be
between 7121 and 6122.

Ge Terry and the group!
Wow, i had to try harder to find an open spot for the 4SQRP net, than i did for the fox hunt last night!!!
This is good!
The signals were great here in Ks tonight, good to hear the nice turnout.

Add anything to the exchange that you wish, temp rig, ant, etc.
Checking into all, sessions is encouraged. We call it the "Clean Sweep".

Also if you go to Dan's Special Deals and scroll down about 1/3 of the way he has a couple kits of toroids. His price per core is not necessarily any better than KitsandParts, but this would give you a good variety of cores to start with.

NOAA forecasters expect a weak impact late in the day on Feb. 26th. So the CME won't be an issue... 
W1AW will be.. so that must be planned for.

FOX ALERT!  
There are two Fox that are reportedly on the prowl.. and they love to tangle with hounds.
They have been reported to be heading into the 40 acre woods... and reportedly will be
seen somewhere between the trees marked 7.030 and 7.050... and this all comes to a
head about 7pm MT (0200z) Tuesday evening. ALL available hounds are encouraged to 
come help mix it up with these two sly and wily Fox.... W9CW and WC7S are on their badges
printed in the foxhole by the  Foxhole Certifying Committee. These two are known to be 
very agile and sly.. and extreme skill may be exhibited by them, care and caution is advised.

ok.. now for the serious stuff - 
1.4 The 40M Foxes will operate within +/- 10Khz of 7.040 MHz.  
That does NOT say anything about where the HOUNDS are to be.....

So be alert, and pay attention to the directions the Fox gives... 
What does the Fox say?   is a good line to remember.!!
Also.. one other aspect may be helpful, the fastest way to get through the pack,
is to get YOUR call heard by the Fox... and the BEST way to do that.. is to put YOUR call.. 
in the CLEAR.. either by giving your call at a time when NO one else is.. timing.. or by
putting it on a spot that does NOT have anyone else there...   IF you are in the middle of the 
pack  -  TIMING is a critical concern... if you are spread away from the pack even just a little..
calling additional times allows the FOX to tune to you... 
So there are two different strategies.. call often??? get away from the pack.. 
Call once>>> time it right and put it right in the pack. 
DON"T do both at the same time... but switch back and forth is good too.

Good Luck to all and to all a good HUNT!!
Catch us if you can...

Their "400 Max" is listed at .8db loss for 100ft at 30mhz.
The RG8X is listed at 1.4db loss for 100ft at 30 mhz.

The 8X is about half price of the 400 on their pre built pieces, plus it's much smaller, more flexible, and easier to route around in the shack. On the other hand, that seems like a significant difference in loss, until I think about how I only need 75' and most of my activity is well lower than 30mhz (usually 20, 40 & 80m).

I do run 100 watt SSB at times, but I'm mostly QRP.

I'm not looking for a dissertation on DB losses, but I thought I'd ask if you guys think in practical real world use, would either I, or the receiving station be able to tell a difference in signal between those two 75' pieces of coax? I know the 400 is "better", but I question how much difference it would make (if any) in the practical sense. I can get two pieces of 8x for the price of one 400.

Think about what in addition you could buy with the other half of that money. Or save it. One thing qrp has taught me is that it is not necessary to spend more, rather than less. 73 Shawn kf7yff

On your end, you would be hard pressed to tell any difference. Yes, your RX signal level would be down a bit, and there is the possibility that on a very quiet band, such as 10m, it could matter. What matters is the signal to noise ratio. And since both the signal and the noise would be attenuated equally you'd not be able to tell it.

One of the big differences if you do not have resonant antennas is the SWR loss of each coax. What may seem trivial at a 1:1 SWR could be significant at 10:1, etc.

You might make some comparisons here:

I plan to replace two pieces of 20 year old coax once Spring finally gets here. One would be for a 10, 15, 20m 3 element beam, and the other for a 135' OCF "horse fence" dipole. As a starting point, I'm looking at DX Engineering coax specs. 


Their "400 Max" is listed at .8db loss for 100ft at 30mhz.
The RG8X is listed at 1.4db loss for 100ft at 30 mhz.

The 8X is about half price of the 400 on their pre built pieces, plus it's much smaller, more flexible, and easier to route around in the shack. On the other hand, that seems like a significant difference in loss, until I think about how I only need 75' and most of my activity is well lower than 30mhz (usually 20, 40 & 80m).

I do run 100 watt SSB at times, but I'm mostly QRP.

I'm not looking for a dissertation on DB losses, but I thought I'd ask if you guys think in practical real world use, would either I, or the receiving station be able to tell a difference in signal between those two 75' pieces of coax? I know the 400 is "better", but I question how much difference it would make (if any) in the practical sense. I can get two pieces of 8x for the price of one 400.

Thanks!
