Hello there,
I am vacationing in Falmouth, Massachusetts, at a Mahony clan rendezvous. Ten of us are in a rented house with various gangs driving down and visiting.
I have put up a NorCal doublet on the elevated back deck, 22 feet per leg of gauge 22 speaker wire. One leg goes to a second story window and the other leg goes through a fork in a tree in the back yard. The center support is a 20-foot telescoping graphite fishing pole. I am using my FT-817 with the Z817 tuner.
I am finding 20 meters so crowded that I can't distinguish a single voice. On 40 meters, I have been hearing people all over the eastern U.S. I haven't yet managed to talk to anybody yet. I need to learn to pounce when an opportunity opens, instead of pausing politely to see whether someone else has been waiting. Pounce, Rhona, pounce!
I am so impressed by your antenna experiments!
Take good care!

Here's a source for the 17' poles...about what I paid for my from Cabelas a few years ago.

I like the hub assembly - with the free rotating

Do you keep the spreaders in position by the antenna wire tension, or do you have additional spreader rope to maintain the angles?

Propagation was really favorable to EU during the IARU on 20m.
I managed to work UK with 750mW and sloper on Sat night.
Also the other HQ stations you mentioned were all booming in here.

Did you use an antenna tuner inline?

Also would be curious to know about any performance tests results.
Maybe some f/b and f/s - wspr?

The crappie poles work wonders. I have a few 20ft ones..but need to get myself the 16ft models...(for 20m dimensions)

Hi gang,

I've been working on a portable version of Martin Hedman's (SM0DTK)
3-element wire beam: The Mini Horse Antenna, QST Mar. 2010.

Although it needs some optimization, Dave (W6VYK) and I got it launched
and operational last Sunday.

Qs with:

KH6LC Keaau, Hi. big antenna farm and station setup for remote
control, check QRZ for details.

AH6NF Honolulu, Hi. Beverly

SK9HQ Karlsborg, Sweden This is a big contest station.

SN0HQ Poland Another big contest station.

The mast was of particular interest to both of us. I've been wondering
how high a mast one could make by stacking surplus 4' fiberglass pole
sections.

Our technique was to plant 2 guy lines roughly 100 degrees apart, then
while keeping the mast leaning evenly against the guys, add sections
from the bottom.

A third guy was tensioned against the other two once we had the altitude
we wanted. We quite easily managed to get the beam up 36 feet. It was a
windless afternoon. Any wind at all would require a second set of guys.

The beam itself is light and could be suspended from a horizontal line
stretched between 2 tall trees. That combination would reduce the weight
enough to make the antenna portable.

I've uploaded photos of the adventure to the photo section.

Dear Gang:

Today I made the first tests on my qro mag loop. My goal was for it to be usable from 14 to 21 mhz at 100w. Unfortunately it tunes from 14.800 mhz to 23 mhz.

Here's my question: is there a way to lower the resonance other than increasing the capacitance across the loop? Should i try increasing the feed loop diameter? Here are the design details;

10 ft loop circumference (+joints) 3/4 copper pipe in octagon shape. Feed loop 24" circumference (using 1/5 rule) made from refrigerator tubing about 1/4" dia, feed high capacitor low. Capacitor massive butterfly, measures 30-60 mf

Using the wide-range tuner in my k1 i did hear a number of stations on 20m so i have high hopes!

Thanks

Give the netbook a try. Let me know how that goes.
Coding: Well I could not find an open API for cwskimmer
so my goal is to diy.

Tony's kit.
Not sure what drove the specs but a multi-band hf txrx certainly has wide appeal. Thats the reason so much activity on the mobokit.

Let me know once ur ensemble is on air psk is a real breeze from within rocky especially in a crowded band.
A 30hz filter works magic.

Deon,

OK on the computer requirements. I did a lot of looking on the web and most of the problems people were having were related to all the extra support software that some power users had running in addition to the basic DSR software.

I ordered the EMU 0202 and should get it next week. I think it offers the best performance and flexibility. It is good to hear that you think even a netbook with Rocky will run at 96KHz.

I agree with your comments on the new Ensemble Tx/Rx kit that Tony is offering. It is a step down from a general coverage rig. It is kind of funny that he didn't offer a consolidation of all the v6.3 add-ons to make a completely general coverage rig on one board. It may have been a cost issue? Send him your comments via the Softrock group. I have found him always to be very responsive. For me the 17, 20 and 30 meter rig covers the daylight bands that we use when we go out on the weekends and it looks like it will be easy to put it in a nice enclosure with all the connectors mounted on the PCB.

OK on the FFT code, I do not see myself getting to that level but for an SDR that's where all the action is.

Dave



Thought I'd comment on your SDR S/W perf question.



The EMU 0202 will require high I/O capability of USB2.0 (which results in more CPU cycles. eg. at sampling rates > 96KHz.



Your netbook platform at 96KHz sampling rate, you should be ok. (Both Rocky & Spectravue max sample rate = 96KHz)



S/W:

While I'm developing my own FFT s/w, most of the experimentation is which these 2:

a) Spectravue seems quite effective and has some FFT adjustments, which will reduce the clock cycle needs.

b) Rocky requires more CPU than Spectravue - but does a far better job of demod than Spectravue and PSDR in my opinion. A plus for Rocky is also the built-in PSK mod/demod.



PSDR - I don't experiment much with this - it has too many bells/whistles which I dont need right now. So I don't have good performance #s.



My platform is WinXP: VAIO VGN-TX770P 1.3GHz CPU.

This setup runs EMU0202 @ 96KHz + Rocky no problem so you should be ok with the > 2GHz clock.



Hope this helps.

Great Dave

I'd be curious to know your feedback on the rx/tx kit.

Ive had great success with my txrx 6.3. operating CW and PSK.

I'm not sure why he did'nt go for a Mobo design?

I think there is great demand for all-band HF.

The switching for BPF is not that difficult afterall.

The single band-group seems too limiting. Now, if you want all

band hf - as I understand, one has to build 3 or 4 x radios whereas with the 6.3, the swapable PA's provided all band capability.

ks fine. It's just a hassle to swap PAs.

I plan to add the Mobo kit to my 6.3 which will give me all band.

I met with Pieter (design engineer for rfspace) at Dayton, and he talked abt the new design he is working on.

It looks very promising - with dual receiver + tcp/ip integartion, similar to the SDR-IP but hopefully priced better.

The SDR tech is really developing fast, and with such simplicity, It's a great time to be experimenting, home-brewing again.

Good luck wiht the ensemble construction.

Do send a field report on the 3 el beam.

I'm experimenting with small size Moxon - just have to complete modeling first.

Glad to hear you're going on the SDR/SMT project.

I'll be eager to hear what you think of the performance.

My RX 9.0 (all band VXLO) is my main hf rx at home. It's impressive performance and 96 KHz means I can be "watching" any HF band while

doing work on the PC.

As far as s/w goes, I find Rocky has the most effective demod for cw and digital modes as well as very simple but effective pan-adapter controls.

For ssb rx, the PSDR or Spectravue has more well rounded audio for easy listening SSB.

I'd wonder what beam you'll be putting in the air? Moxon, Spider, Hex?

Great Dave

I'd be curious to know your feedback on the rx/tx kit.
Ive had great success with my txrx 6.3. operating CW and PSK.

I'm not sure why he did'nt go for a Mobo design?

I think there is great demand for all-band HF.
The switching for BPF is not that difficult afterall.

The single band-group seems too limiting. Now, if you want all
band hf - as I understand, one has to build 3 or 4 x radios whereas with the 6.3, the swapable PA's provided all band capability.
ks fine. It's just a hassle to swap PAs.

I plan to add the Mobo kit to my 6.3 which will give me all band.

I met with Pieter (design engineer for rfspace) at Dayton, and he talked abt the new design he is working on.
It looks very promising - with dual receiver + tcp/ip integartion, similar to the SDR-IP but hopefully priced better.

The SDR tech is really developing fast, and with such simplicity, It's a great time to be experimenting, home-brewing again.

Good luck wiht the ensemble construction.

Do send a field report on the 3 el beam.
I'm experimenting with small size Moxon - just have to complete modeling first.

Deon,

Good to hear from you. The receiver is the Softrock v8.3 with the add on USB interface. Tony has a new intergrated RX/TX kit that you can configure for any single band. I have one on order and will build it for the 17,20 and 30M band. I am about to order a E-MU 0202 but I am not sure my laptop (2.2 GHz P4) or the netbook have enough horsepower the run the 0202 and the SDR software?

Neil is building the 3 element beam described in the recent QST article. We plan to use the 4 ft. surplus fiberglass poles to get it up about 30 ft.

Dave



Glad to hear you're going on the SDR/SMT project.



I'll be eager to hear what you think of the performance.

My RX 9.0 (all band VXLO) is my main hf rx at home. It's impressive performance and 96 KHz means I can be "watching" any HF band while

doing work on the PC.



As far as s/w goes, I find Rocky has the most effective demod for cw and digital modes as well as very simple but effective pan-adapter controls.

For ssb rx, the PSDR or Spectravue has more well rounded audio for easy listening SSB.



I'd wonder what beam you'll be putting in the air? Moxon, Spider, Hex?

You need to use a good liquid flux or you get cold solder joints! I need to wind a couple of toroids to complete the band select filters and I will give the thing a listen.

Hey Dave, Thanks for the offer, but our younger son graduates from college on Saturday. However, if you see a small variable cap in the 0 to 100 pf range, can you pick one up for me. The PG&E RFI sniffer guys need one for a loop. One with a wider range could be used if nothing else is available. Thanks! This article on solar activity was on the Yahoo news page today. Very interesting. http://news. yahoo.com/ s/space/20100609 /sc_space/ moreactivesunmea nsnastysolarstor msahead Good luck with Neil's 5 element portable Yagi.
