The maximum power radiated by a short monopole antenna system may be
calculated using equations found in standard engineering texts.
The link below shows a system with a 50 ft monopole radiating 1 watt EIRP on
630 kHz using the values shown for the r-f loss in the loading coil and r-f

Ahh but I think the FCC will see things much differently. I base this on
the existing 60M regs where an ERP is specified:
(i) No station may transmit with an effective radiated power (ERP)
exceed- ing 50 W PEP on the 60 m band. For the purpose of computing ERP,
the trans- mitter PEP will be
I would disagree. The signal measured along the ground is affected by
ground losses and is subject to ground conductivity even though the
charts show maximum gain along the ground. The signal radiated at angles
above about 10 degrees is governed by inverse distance and therefore
less loss. An
That is not what I said. The skywave would only be stronger if field
measurements on the ground were used to determine power due to various
ground losses, ground conductivity, etc. when an RF ammeter is used for
measurement (standard practice
I should have asked this question during the contest but was a bit busy.
Did anyone try to work us at PJ4X and not get through?
Our 160 station was on 160 and 15 and both bands had receiving problems.
Additionally, we don't think our US Beverage was working very well. West of

I'm assuming that you were at the house on the hill that Noah owns with

Okay - I think we have hashed this one to death - thanks for the input, but

Thanks.

Further - and this has gotten beyond the 160 meter scope of this list -
630 meter propagation will be almost entirely groundwave as ionospheric
conditions generally do not support skywave (a primary reason for the
use of LF and low MF for NDB). Since skywave is not supported, it

I am sure Craig's post was not meant to be critical, and we cannot presume
this was the problem. We do not even know whether they were indeed at
Noah's station. There are now at least two well-equipped contest stations on
PJ4.

I hope everyone has the correct info now.
Any questions send me a direct email.
Also the European broadcasters just below 200 khz are frequently logged in

I regularly copy the LF BCB from EU/AF and the Mideast down around 200KHz
when skywave is good. Granted they run super QRO but they have poor ground
efficiency and are meant for country coverage only,

I hooked up the hub today, and initial results are excellent.
For those who missed earlier messages - here's the story. I ran across
an inexpensive 8-way relay board on E-bay for less than $20. It is
controlled by a 300-MHz radio remote, and I figured I might be able to
use it for remote
Absolutely! Switching multiple RX antennas is always a major headache. Ive
been scratching my head so long trying to figure out how to handle 3 hubs
Ive worn down my fingers since the skull is so thick!!
How about more info on what and where you actually bought?

Craig,
My first attempt around 0355z failed but about 35 minutes later it was
pretty easy. I ran 100 watts to an inverted L (65 feet vertical and about 70
feet horizontal) with 3 quarter wave raised radials on 160.

Javi and Elmo have apparently arrived on Bioko Island, Equatorial Guinea
and QRV as 3C6A. They will be there until February 26th. From February
27th to March 11th they will be on Pagalu Island, more commonly known as
Annobon Island, operating as 3C0E. To my knowledge no one in the US has
worked
