On CC&R DXpedition Model | Project 3BTV Halted



The property in front of our terrace belongs to the home owners association (HOA). Theoretically, my 3BTV was a good fit however raising HOA attention was not and we decided against the idea. Initially, the antenna seemed concealable enough then once I raised the aluminum, its mass was visually inescapable. Yet, I felt Project 3BTV, was achievable.

Retreat was necessary.

Problems seeking solutions.

I decided being pragmatic as a practical approach. The above photograph visually describes the obstacles confronting Project 3BTV. A ground mounted vertical 4-inches above adobe like soil sandwiched between a pair of condos is not effective. My 88-foot doublet fed with 450 Ohm window line deployed on a 33-foot push-up mast is, hands down, a better antenna system given this set of problems.

21st Century Antenna Systems.

There is little wiggle space for anything approaching a normalized antenna system. This is perhaps a common theme for some but not all low-profile high frequency (HF) operators. Antennas designed for open spaces with sufficient vertical and horizontal dimensions are 20th Century.

Wanted to bring everyone current on Project 3BTV this evening. I finished the copper loop for the radial system and will solder the connection this evening. The radial system loop is an old piece of 12AWG +/- 2AWGs of stripped copper wire. I spent Tuesday evening removing inch length pieces of insulation. And caught up on a few Pod Casts as well.

Has anyone seen the price of copper? I have. And I'm suffering from copper shock. I'm cutting 1/4 wavelength radials for 10, 15, and 2om this evening. I purchased 500-feet of insulated 14AWG stranded copper wire for sixty dollars. There is enough copper wire in the shackadelic to build antennas for many years to follow.

Soldering of the radial system follows tomorrow evening. Then I'm deploying my 3BTV for standing wave ratio checks through Saturday afternoon and low-profile locations in front of our condo unit. I want to find a location that is both neighbor and reception friendly. Expect pictures to follow on my CC&R DXpedition Model | Project 3BTV through the weekend.

Contest on.

I1UJX provata a T7

08 Novembre 2008 | Archiviato in: DXpedition, IZ4AKS, it, news



Ho investito una mattinata con Alessandro T77Z (nella foto) per provare l’antenna di I1UJX. All’inizio tutto bene, risuona a meraviglia e arrivano anche segnali da lontano. Poi, il disastro. Abbiamo capito che qualche cosa non andava quando hanno cominciato a passare da dei 599 a dei sonori 595…SWR impazzito. Risultato 26 QSO come T77Z e una bella “partita di chiacchere” sulla radio e sui dx.

Probabilmente c’era una saldatura fredda o il cavo con qualche problema. Meglio saperle prima queste cose che scoprirle durante la dxpedition.
Ad ogni modo la cavetteria delle cuffie ed il pedale sono andati bene, posso spuntarli dalla check list; la loro custodia può finire nella cassa.

Un grazie a Alessandro e all’ARRSM per la disponibilità e l’amicizia.


Sazan Island (EU-169) Dxpedition 2008

04 Novembre 2008 | Archiviato in: DXpedition, MM0NDX, en, news
Thanks to Alfredo IK7JWX for providing images and small report on the recent ZA0 / Sazan Island (EU-169) Dxpedition.













“From 23 to 29 october 2008 we were active from Sazan island (Albania) iota EU-169, M.I.A. MA-01, LH. ALB-004 and L-0028, and also in the CQ WW SSB contest.

Our score was 15.228 qso :ssb, cw, psk31, rtty, meteor scatter, 10-15-18-20-40-80-160m, Op. ZA0/(h.c.) :IK7JWX, I0SNY, I8YGZ, I8LWL, IK2AQZ.

Perhaps we can participate for “the best dx-pedition 2008 in Europe”? I am the qsl-manager for all the op., but “only” for the members of our good sponsors GDXF anf CDXC.

Best 73
