John, could you provide a few details on your antenna and feed arrangement.   Is your 33 ft all vertical orientation?   I need to have something on 40M and getting 20M would be a bonus.

New net format...

Wayne Dillon
 

Good morning all,
The "new" net format, i.e. building a list and then calling each station in turn seemed to work OK last evening. I have to say it's not a method I came up with, rather a method that Charles (W2SH) tutored me in last year and now it seems so natural a way to work. So, a big public thank you to Charles for taking the time to guide me and be a steadying hand, it is much appreciated. This will therefore be the format going forward. Also I am using N3FJP's AC Log to do general logging which has a great "NET" feature which allows the building of the list as well as adding all the relevant data. Also, it's compatible with the data out of all my radios except the single band jobbies (MFJ 9020/QRP Plus/ SWnn+ series) which helps my fogging aged mind remember to put the frequency etc. in the relevent boxes. If you're looking for a great logging program I'd like to suggest that you look at Scott's product. No I have no connection to this product except being a very satisfied customer.
I'll likely hang out on 7.122 over the weekend daylight hours, as often as other "stuff" permits, switching to 3564 as the gray line passes and night falls.

Got the Orange Kirinite knob finished a few minutes ago, mated it with
the skirt & mounted them on the key - came out pretty. Didn't like that
8-32 nut locking the upper contact in place so I machined the skirt off
a brass knurled nut like those on the adjustment screws and used that
instead. Looks a lot better. Changed the cable to a smaller diameter
one that's very flexible and put a decent strain relief on it.

Also got it's little brother in from Morse Express this morning. To go
in my Bayou Jumper case, I bought one of their last remaining 2005
"Christmas" keys and it's a cute little bugger. The return spring was
WAAAAY too heavy though even at it's lightest setting and I wound up
having to clip 2 turns off of it to make it comfortable to send with.
It's even 18 carat gold plated! I don't particularly care for the round
top wood knob, but it is what it is and it does work for sending CW -

Nice net Wayne, prop seemed fairly good in the Heartland tonight.  At 8:00 I heard WA9PWP and KK5IB calling. They both had good signals and worked each other.  I suspect they thought the net was at 8P.

80M seems to be the evening band of choice for the next few years.  I've always enjoyed it and will start hanging out on 7122 in the daytime and 3564 in the evening.  Hope to work a buncha Four Staters.

Thanks again for calling the net.

BJ oscillation

Thanks to whomever advised me to try a BS 170 when my Bayou Jumper oscillator wouldn't oscillate. They suggested I may have popped my 2N7000 as they are fragile. Got some BS 170s and put one in. "Oh the joy of oscillation!", as Bill Meara of Soldersmoke fame says.

I have a box of 40 meter crystals and all but one worked too.

Now to get to the FDIM Buildathon and build a crystal checker and learn how to grind crystals. That is Rex's project this year.

Reminder about tonight's nets

Wayne Dillon
 

Good afternoon all, here is;
Tonight's 40m net will be held on 80m - 3564 Khz.
The format is slightly different, I will do the usual CQ 4SQRP de NQ0RP QNI K and when you drop your call in I will respond with  R R urcall urcall pse AS. This means you are on the list so when you hear R R urcall pse AS just hang in there and I'll call you in order when I've got a list made up. That way I believe is fair to all and a little more organized for me. I'll also be using N3FJP's AC Log with the "Net" facility. I'm on a learning curve here as well so bear with me.
OK, c u all at 01:30z (19:30 cst) on3564 Khz.

Ozarkcon 2017 Pre-registration now open

Paul Smith
 

Good morning all,

The online registration for Ozarkcon is now open. Below is a link to the registration page. We have a GREAT line up of speakers and Branson is beautiful and waking up from the winter nap in April.

This year's Ozarkcon is April 7 and 8 at the Stonecastle hotel. The room rates are the same as the last several years at $69.00. When making reservations please ask for the 4SQRP room block. 

Ed and his bride have a prize list that will knock your socks off with a Elecraft KX2 as the grand prize and many other nice prizes and kits as drawing prizes.

I hope to see you all there

I think the original NorCal Doublet was made from 4-conductors of a computer ribbon cable. Since the outer two conductors are used with the inner two spacing the conductors apart your speaker wire probably has a vastly different impedance. That may not matter for your question.

Did you cut and tune the antenna for 40M before using the tuner since that's your favorite band? I'd start by putting the tuner in bypass mode and adjusting the SWR on you favorite 40M frequency first and then let the tuner take you other places as needed.

This method gets dipoles where you want them with a minimum of fuss:

Dipole Calculations -- 2 Adjustment Method.

F = target frequency
L = length of dipole in feet
M = "magic" formula constant for 1/2 wave dipoles

L = M / F

Example F is 7.150 MHz (middle of 40 Meter band)

L = 468 / 7.150 = 65.45 ft = 65 ft, 5.4 inches

Build the dipole to this length. Leave the ends temporarily connected so the length is easily adjusted later.

Install the dipole and measure the SWR across the band. Note the frequency of the lowest SWR.

For discussion purposes lets say our SWR minimum was measured at a frequency of 7.20 MHz. The adjustment needed is:

Adjustment = F(SWR minimum) / F(target) = 7.200 / 7.150 = 1.007%

Our wire length needs to be 1.007 * 65.45 = 65.91 = 65 ft, 10.92 in.

If you adjust the wire length to this new length the lowest SWR should be exactly where you want it.

Why is the length different than the "standard" formula? "468" is the constant needed to calculate the length of the dipole under perfect conditions with a given wire size, no insulation, etc. You did not use those conditions and materials for your dipole. Using the above method compensates for not knowing all of the technical details of your feed line, antenna wire, etc.
