Their final logs were posted this afternoon; final tally 18 slots, 9 bands, 3 modes. I'm so thankful that I managed to grab them on topband an hour and a half before they went QRT for the last time. I guess all my shlepping back and forth through the snow-drifts to fix my loop paid off in the end! Fantastic operators.

Also, those verticals looked to be simple quarter-wave verticals and not the usual vertical-dipoles that have had so much success in other operations.

Stan SQ8X has hit the proverbial nail on the head.  Check out the VP8ORK comments on DX-World.net

VP8ORK (just like ZL8X and T30OU) was a very good proof that even a single db (or two) of antenna gain can make a all the difference.
Both were just a BIT over noise with my 2el wire beam. I'm very sure that I would not made it with a fixed dipole or a vertical.

Some said that VP8ORK was not for "small guns". I'm a small gun. Why am I telling all this? To encourage fixed dipole guys to consider the simplest rotatable lightweight beams. What's there for me? The more dx-capable stations we have on the air the better Wink
And my county hunting becomes somewhat easier Wink

Aadu,

With all due respect, 900W puts you into some higher class beyond "small gun"!  Grin

Well..you could just have 900W radiating from a rubber duckie, or a SpiderBeam  Roll Eyes..where the frustrated RF just rolls off of the end of the antenna and flops onto the ground and dissipates (some RF does evaporate into the atmosphere, & get's carried away by the "trade propagations" of course).

You could have added quarter wave vertical to that list..... Perhaps that is why I had so much trouble working them. Of course MY problem was HEARING them. Each time I heard them (two bands), I WORKED them. (Yep, I DO miss my tower with the little Force12 C-3SS tribander)

Hi All

I should mind my own business I guess BUT - 900 watts dose not make you a Big Gun - neither dose 1500 watts - It is the antenna system in my humble opinion along with the KW that makes you a big gun.

Example no# 1 My neighbor uses a KW plus and calls in pileups till his face is blue , or his finger falls off from sending. Speaking of Top Band , him using a KW plus into a 43 foot vertical with no ground radials might as well use his dummy load. He also uses a antenna called a All Bander . I have been in pile ups with him running 100 watts and work a station in few calls while he never works them. 98 % of all my contacts is with 100 watts.

My antenna on 160 is T over 30 130 foot radials and I will go to 60 radials plus this summer.

My antenna on 80 is either a Super Loop 80 or T with 2 elevated radials. The Super Loop 80 was a worthless antenna trying to work the VP8ORK - The shortened 1/4 vertical T 4 meter above ground with 2 elevated radials and 100 watts was what  worked . The 500 foot Beverage also was a big help.

This  was one of the Greatest DXpeditions I have worked and any time you work the Antarctic Islands you will find it to be tuff conditions .
 

I heard them on all bands  except 10 ssb and that is poor propagation to my area.I put the time in listening also. It sure was not my 7 el 10 meter beam at 70 feet being at fault. That beam dose not make me a big gun either . A stack of 3 might put me in that class of big gun  on 10 meters. I agree  it is above little pistol though.

My hat off to VP8ORK team  and a Huge Thanks for new bands and modes.

That would be great topic - What makes you a big gun - What antenna did you use to work VP8ORK -

73 JIM


135' long Inverted L with 20 radials (33' each) on 160 (400 watts)
66' long vertical with same 20 radials (plus tuner) on 30 (100 watts)
100' long center fed dipole (plus tuner) up 40 feet on 40 (100 watts)

Pretty sure this counts as little pistol (maybe not so much on 160).

At some point, skill (and luck) comes into the equation too.

This winter, I am set up for operation on Top Band only, using a short top-loaded vertical (Cushcraft MA160V) and a small receiving loop.  I was able to hear VP8ORK easily on all bands 160-15 meters on my 160m vertical.

I was only hoping for a 160m QSO, but I also managed a QSO on 30m running only about 45 watts with a 3.5:1 SWR using the same vertical.  The CW operators were fantastic, keeping up rapid QSO rates.  Most of the time, I only had time to send my call once before the VP8 was coming back to someone.

"It is the antenna system in my humble opinion along with the KW that makes you a big gun. "

I agree! I sorta found them when I looked for them..

"What antenna did you use to work VP8ORK?"

3-Element SteppIR w/30-40M option, plus a little help from my friend Alpha

Hmm, well, that makes my two contacts with my 31' wire vertical w/16 radials and about 800 watts seem a little better. Once I could HEAR em I could get em, even tho they did ask for my call a couple times. Sloppy fist.... heh heh    Gene

I really never gave it much effort as I've had the tower cranked down when I did snag them...After work one day I checked & they were there on 20M..and later on one day I checked & they were there on 40M..It's not like I hunted high & low & sat for hours trying to hear them...I have them on 20M & 40M SSB, that's all..never really gave it much effort as far as other bands, etc...I heard them on CW few times but really didn't bother with it...

The one I really want is ZS8M..but look's like that's gonna be for a later time. I just got the tower work done & it cranked back up this past Friday..

What makes you a big gun - What antenna did you use to work VP8ORK -

10-15-20: Force-12 C31XR at 72 feet AGL. 3 elements on 20, 4 elements on 15 and 7 elements on 10m on a 31-foot boom
12-17-30: Force-12 2/2/1 at 85 feet AGL. 2 elements on 12, 2 elements on 17 and a rotatable dipole on 30, on a 7' boom.
40: Force-12 Delta 240 (shortened 2-element 40m) at 75' AGL
80: Inverted Vee at 70' apex
160: TX: Inverted L, vertical portion roughly 50-55' AGL with about thirty radials. RX: commercial K9AY Loop (also RX on 80).
Power: Legal-limit from an Ameritron AL-1200.
Transceiver: Mark V
Heil mic and Bose headphones combination.

Big gun? Maybe biggish, but nothing like the stacks on most decent contest stations, plus I'm hobbled by nearby higher terrain over 180 degrees (north-northeast, through east, to south-southwest).

Vertical dipole and 100 watts on 20m CW and SSB. Strangely, I had a far easier time working them on SSB than on CW. The opposite is usually the case.
