Telescoping Fiberglass Mast - again...

16. února 2009 v 19:11 | Petr, OK1RP |  Antennas

Hi all,

just few days ago I found very interesting informations about another solution for support of the wire antennas like Inverted L, verticals etc. specially on 160m.
Please read an article about the common pluggable mast-system which is very useful for portable, DX-pedition or fixed station usage. A smile-price solution of best surplus quality is promised by company owner Jürgen Simon,
The Material:
GRP - glass fibre reinforced plastic, one of the stablest material used in modern life. In this case here even with more stability through a special building technolgy. These poles are made from a glass-fibre-tape which was laminated shift by shift until a wall-thickness of 3,0mm (!) is achieved. The result is a ultra-stable tube perfect for our ham-radio use. The former mission of these masts was carrying tent-tarps. wall-thickness: 2,5mm minimum

Dimensions and weight
total length:1,30m - eff. length:1,20m
weight: ca.1 Kg - diameter: ca. 35 (+0,5)mm
wall-thickness: 2,5 mm+
3 = 3,60m / 4 = 4,80m / 5 = 6,00m / 6 = 7,20m / 8 = 9,60m / 9 = 10,80m

I had no chance to test it but it seems very interesting at least. I am thinking about purchasing of set to test it for installation of Inv.L on the garden. Most important information is missing -> how much is willing to bend the mast on the top in case of lenght around 10m or more.
If anybody has an experiences with this mast then let us know over here please.

Switch mode rubbish on 1810 - 1860 kHz in UK

16. února 2009 v 18:41 | Petr, OK1RP |  Operation topics

maybe You are remember my article about forbiden frequencies on TB...

I asked all of You to let me know if some frequency is permanently unusable or QRMed in Your area to put it to the table .

This information arrived from John, G3PQA:

During the last month I have been hearing a new source of qrn which seems diffierent from the usual local switch mode rubbish. Only audible at night, and strongest on 90 deg. east beverage. Up to s7 at 2130z, s9 at 0130z, on east beverage and audible on all others. Not listened later in last couple of weeks, so dont know yet what time it disappears, but DF-ed it at 70 degrees - difficult to get accurate bearing as it is skywave. Sounds like power line qrn with phase distortion, a bit like the old Loran at a much higher frequency. Spreads from about 1810kHz to 1860kHz, strongest around 1839kHz.

I suspect it is coming from east UK or west EU, but difficult to locate without other reports.
Later on I will make recordings and try to DF from other locations.

Does anyone else hear it, (or have an idea of what it might be)?

Thanks 73

If You have some similar experiences or even You know whais it then do not hesitate to email me to share with other Topbanders. Also please reply to John if possible.

Ukraine band plan for 160m

16. února 2009 v 18:27 | Petr, OK1RP |  Band plan
Hi Tree and all,

The limitation of ten watts in the Ukraine on 160 meters is kind of
Soviet times mark. It still exists, however many of contesters have
gotten permission of 1K up to 30 MHz. I got my some ten years ago. New
regulations are being worked up now. We hope we will see some positive
changes in it soon.

See you on the TB then. Last night W8LRL was the only NA called me. The
signal was quite good 579 w/o noticeable QSB.

VK9G - Mellish reef on 160m

16. února 2009 v 18:21 | Petr, OK1RP |  Band reports
G'Day Topbanders,

Tomi (HA7RY) and I are heading out to Mellish Reef to
operate as VK9GMW. We will be active between Mar 22 and
Apr 6. (Dates subject to change due to WX.) We will have a
strong TB (and 80 m) focus, although we intend to operate
on the other HF bands too.

For more information and updates please see

73 and CU in the Pile-up!


This information was posted by George originally on Topband mailing list so it is good chance to catch Mellish reef on 160m band if condx will be ok.
Any informations about the QSOs from EU (or even from OK land) are appreciated of course.
