RMRc cw practice net

Dale Putnam
 

The Rocky Mountain Region and Continental cw practice net will be called today at 4:15 pm MT or 2215z on 7.0625
and again on 14.0625 at 2245z or 4:45pm
Come practice your cw .. at your speed.
Today.. when you check in, I'll let you know my temp, your rst, and if you can copy any others, and want to say Hi to them,
please let me know. I will let you two chat for a couple exchanges, after we check in folks. Swap any numbers.. or QTH info.

See you this afternoon.

Have a great day,

Hi Mal,
 
It was nice to work you in the net.
 
YES!  I do want relays.
At the end of every net I always call for "Any QSP?" but I didn't hear anything last night.
Thank you, that would be a big help on nights like last night and it might make the difference for a station or two that are trying to QNI.

Thanks for enduring Bill, I know what you mean about the QRN.

I I copied a KD0WF trying to get in the net. His signal came up at the end for me to a 449.

Do you want relays when this happens ?(assuming you'd still hear me)

Thanks again and bst 73,

Yes, that was me. I tried a few times but, I guess because of the noise, Bill could not catch my call.

Well that was downright brutal! (But still fun.)
I think I heard every lightning crash in the U.S from 7:30 to 8 p.m.
The persistence award goes to Ken WA8REI.
He repeated his call enough for me to get it - one letter at a time.
Thanks Ken

There may have been another one (or maybe it was just my ears ringing from the static).
I'm sorry if I missed someone. Let me know if I made any errors.

Re: QRO Operation Question

FB on your service!  Obviously you have the right idea to separate the antennas.  Note that each rig likely has the ability to adjust its output power.  I would start with low power transmitting tests with each rig, and work your way up in power.  We have run lots of radios in close quarters without issue, but each situation is different.  The filtering in each rig may be sufficient along with antenna separation, proceed with care and likely things are ok.  I believe we still have a similar communications vehicle here in Maryland - maybe some web research will find some info. 

The antenna switch idea is a good one for lightning protection etc.  Something high quality that grounds the unused antenna - and yes for safety some electrical ground should be researched.  Whether you can afford the dummy load hardware may be another matter to consider.

Re: QRO Operation Question

Don Wilhelm <w3fpr@...>
 

Darryl,

I would suggest that you equip each radio with a 2 position coax switch and a 100 watt dummy load.  Switch the radio to the dummy load when it is not being operated and to an antenna when it is used.  That is the fail-safe situation if only one radio is to be used at a time.

OTOH, you mentioned only two bands - 40 meters and 70cm.  If operation is confined to those two bands, they may co-exist just fine and even allow simultaneous operation if both transmitters are sufficiently clean.  If there are problems, a 30 MHz low pass filter in the HF antenna line(s) should cure it, and a High Pass Filter in the VHF/UHF antenna line(s) will even allow simultaneous operation with no problem.
If you have more than those two transmitters, a set of good bandpass filters for the HF bands would be in order.

The UHF radio will be running 10 watts on 443.150, and the HF radio will be running 100 watts on 7.260. Should I turn the non-operating radio off when I am running the other one? Disconnect the antenna or just turn the radio off? Your suggestions appreciated.

Re: MP/PM

dekle@...
 

For the English alphabet, if using the same letter twice is permissible, it is

n**r  =  676 possibilities.

if the letters must be different it is

n! / (n-r)!  =  650

For the Khmer language, 2-letter permutations with repetition allowed would be

74**2 = 5476 possibilities.

Hi,

I have used 24 hour time format (sometimes referred to as "military time) since my teens and I automatically see 16:00 when the little hand is the 4 and the big hand is on the 12 (remember hands?) with a westering sun. But other people - those who use "kindergarten time" use PM to mean after noon. Context is everything but can be inadequate.

I have a 32-foot fiberglass pole which collapses to about 3 or 4 ft. total length.  I believe it was marketed by MFJ several years ago.  It has a loop on the top so you can attach a wire; you only need extend it as far as you want for a quarter-wave vertical on any band 10 through 40 meters.  It can be taped or tied to almost anything - fence, deck railing, etc..  It makes for very quick set-up.

Re: Punk antenna

Don Wilhelm <w3fpr@...>
 

Doc,

If you are only interested in 40 meters, the best solution is a dipole fed with coax and a push-up telescoping pole to support the center - a couple of test stakes and a bit of mason line will allow you to quickly erect an inverted Vee.

I like center fed antennas because they are less troublesome and have a low impedance feedpoint.

You might ask what happens if you do not have enough horizontal space for the inverted Vee configuration.  My solution is to create a vertical with one radial from the same antenna - use a 32 foot telescoping pole, and connect one end of the antenna to the top of that pole - push it up and string out the single radial (the other half of the dipole) along the ground or bushes as best you can (it can even bend a bit) - it will radiate just fine as a vertical.

The telescoping pole can be anchored to most any convenient vertical support with a couple of bungy cords.

The real solution is the 32 foot telescoping pole.  It can make a very versatile full size antenna for you.  It will be resonant so a tuner will not be required.

I have recently been given a neat 2 1/2 W crystal controlled transmitter (7.030 and 7.040 crystals).

My plan is to put together an ultraminimalist station.  Believe it or not, I have a Sony SW 7600 portable which receives CW really nicely. I have a tiny Whiterook Products MK-32 sideswiper key. And a 12V for the TX power. 

What I want is the simplest TX antenna that would work for this.  I could use my 40M dipole here at home, but I really want some smaller than that for taking the station to the park, picnics, etc.

The best idea I can up with is a hamstick, but I afraid that the efficiency will be so low as to simulate a dummy load.  Is there some kind of vertical other than a standard 1/4 wave I could use?  A full 1/4 wave vertical is a no-go.

I'd rather not use a tuner although I have a good one...I really would like this to be as simple as possible, just for grins...

Thanks for the info about cutting the mat.  Based on Dale's comment, I'm thinking maybe I should not cut it. I'll see if I can fold it or make it fit the work space somehow..

Tim, as for the snap location, with this one the snap is not installed so I can punch a hole in the mat and mount it in a convenient spot after I figure out exactly where I am going to put the mat.
