2. Where is the current best starter documentation?

Probably the two best are DM780 or FLDIGI.  I personally use FLDIGI all the time, because of it's cross-platform capability (I can use the same software in both Windows and Linux).  Works great on Win7 - that's what my radio desktop runs usually.

As far as documentation, there's plenty out there.  Most of the difficulty is getting your interface set up right, and your volume levels correct.  For my own purposes, I feel that using the Signalink USB is the best solution - this device essentially becomes a second sound card connected to your computer - this way you can configure the software to use the signalink, while your "normal" windows sounds still use the primary sound card on the computer.  Plus, the pre-made cables make the setup a no-brainer.  I myself use the Signalink, with their cables and a plug&play jumper board to fairly easily change between my FT-920 and FT-817.

Just my 2 cents worth,

With an additional hour of darkness, 40m signals in NJ were stronger for the second net than the first. However, strong SSB QRM kept me from repeating my earlier QNI.

On 80m nothing was heard here.

Guys, 
I wonder if anyone else has spotted this intermittent problem at QRZ.com ? 

I have noticed a difference in 
1) the QRZ.com reported "Distance" 
vs.  
2) the "Bio page" "Detail map" reported "Distance".  

Sometimes it may be 40% milage off. 
Most of the time it is the same.

So, the question next is, running QRPp , 
if I apply for a "1000 miles per watt certificate", 
which figures do I use ?  

Have submitted a Service Requist to QRZ.com. 
This example is just the latest, 
not the big one, at 1600 miles on a Watt of power. 
This problem is not 100%, just often enough to be spotted. 

Anybody else spotted this problem ?

Re: LT SPICE circuit draw and simulate program DOWNLOAD

Glen <glene77is@...>
 

Nick, WA5BDU, 

Have purchased the HiPerMite and the NeScaf filter kits. 
Have designed/breadboarded a Butterworth BandPass quad stage audio filter.  
Has been interesting to research this field, in order to design/build my 'own' active filter. 
Plan to add my active filter into the HW-8 circuit, and put the other two in an off-board cabinet. 
Has been very interesting to go through all this process.   

Have Multi-Sym running,  and my old LTspice on the shelf.
Have not been great at either.  Wish there were Linux versions of these. 

On the HW8, I have experimentally discovered that the "N"arrow filter is 600Hz. 
Have calculated from the schematic that this is so. 
Will be raising it to 750Hz,  so that the "N"arrow matchs the Transmit Offset of 750Hz. 
The method is to alter the R(2) which pulls two caps down to ground, by lowering the value. 
On the Butterworth , I simply lower the R(2) value by -40% .  
Results will be that Q will drop -25% aprox,  and the Freq(center) will raise +25%  aprox.   
This works predictably on my five stage bread-board Active Filter Project. 
Matches my calculations close enough, monitoring with the O'scope. 

Regarding the HiPerMite Freq(center). 
Any suggestions for raising the HiPerMite Freq(center) from 700Hz to 750Hz, 
to match the HW-8 Transmit Offset of 750Hz  ?   

It seems simple enough to move the HiPerMite #4 HiPass stage down with a padding cap. 
But that would make the mis-match worser. 
I want to move the three LoPass stages up 50Hz. 

Maybe I should just "breadboard" the kit, and tinker ? 
I am familiar with BandPass Butterworth  calculations, 
but the HiPerMite is a Lo-Lo-Lo-Hi design, 
and I wanted some suggestions before I started re-calculating everything. 

Have designed a Butterworth BandPass Active Filter, of five stages, low Q, at 750 Hz.  
On the Butterworth , I simply lower the R(2) value to ground  by -40% aprox .  That pulls both caps down. 
Results are that Q drops -25% aprox,  and the Freq(center) raises +25%  aprox.   
Acceptable variations in my circuit.   
Everything is calculated prior to changes, and the O'scope is used for measurements. 
In the beginning of this study, I used a calculator for everything, 
however K7MEM had some modeling suggestions. 
So, now, in practice, 
I calculate everything, using the K7MEM website and MikeYancey website modeling pages. 

So, I wonder if there is a particular perspective to use in changing the HiPerMite ?

Terry is out of town so I'm going to pick up NCS on 80 meters at 8:00 pm central time.
I have some really strong local QRM so qsy up a little and look for me please around 3566?

Either Wayne or my self will be NCS at 7:30 and 8:30, I am not sure which, but have a listen and someone will be calling Cq, who knows might be both of us??

This is your reminder message that the August luncheon "chat and chow" get-together is this upcoming Saturday, the 17th at the Country Cupboard restaurant in downtown Seneca. Lunch is at 11:00 in the meeting room.

8-13-13 WC7S (NCS) -3- WC7S KK4LPG AA7CU (second session) (2245z)
 
We had a total of 10 stations, checking into the two nets. In the expansion to two nets for the
check of propagation, and avoiding the T-storms, the additional comment that maybe 40 would be better.
It seems that 40 would be interesting to address, although, it likely wouldn't be long enough to gather in both coasts,
at our net times. I'm looking for input, so if you have a "druther" bring it forth, or state your preference,
  Survey time:
 
  1. 1 net or 2 ?  (Which would be easier for you to meet mostly).
  2. 20 only or 20 and 40 (see above)  14.0625  and 7.0325
  3. Time of day... Morning or afternoon, (done by 2230z)
  4. Days of week.. (I can do two days..durng the week)
 
Understanding that not all the net checkins read this reflector, consideration will be given to those that don't.
 
Thanks for your help,



Have a great day,

SOLAR AND STOCK CYCLES ABOUT TO FLIP?

Phil Anderson
 



Hey Guys,

It's not likely that there is a significant correlation of the Sun's Magnetic Field and the market's SPY ETF!
At the same time there must be some crossover in that solar activity can affect the agricultural economy.


According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip.

"It looks like we're no more than three to four months away from a complete field reversal," says solar physicist
Todd Hoeksema of Stanford University. "This change will have ripple effects throughout the solar system."

The sun's magnetic field changes polarity approximately every 11 years. [as reported in the CQ Insider Report].

Re: Last night

Phil Anderson
 

Hey Charles,

I'm beginning to believe that I could have done better by switching between my vertical and my NVIS dipole.
The SteppIR 33 is a pure vertical and I have a lot of radials in the ground; hence it has a low angle of launch
and very little energy vertically or even at an angle of say 85%, which would cover Lebo, KS, etc from Lawrence,
KS. The NVIS dipole, on the other hand delivers much less for DX angles, like to your location in NJ.

Think I'll look at using some sort of combiner on RX; that is, one could bring in the coax from both vertical
and NVIS dipole and listen to each simultaneously, or with left and right ear?

The NVIS should have less noise since it does not "hear" static from distant stations. I'll email those details to
you separately.

Between 0030Z and 0130Z WØXI was consistently RST 559/569, but my
various attempts to achieve a QSO were unsuccessful in that all I
could elicit were di-di-dum-dum-di-dis and SRIs.

Also heard were AA5CO, K5EST and AK4VL, all with decent readability,
but no QSOs resulted.

It should be noted that my NJ QTH enjoyed about 80 minutes more
darkness than WØXI, and that enhanced my reception considerably.

My only QSO was at 0133Z with KB4QQJ, he being only five degrees of
longitude to my west.
