Subject: ALPHA 91 B - GOOD OR BAD ?

Those on the reflector will know I am looking for a new linear. One 
that can take some caning in a contest situation.

The Alpha 91 B looks pretty good on paper. However I did hear that 
they blow up - especially if they have a dodgy power source such as 
DXpedition generators. I'm unlikely to do that, the supply is 
relatively stable here (only varies from 210 to 270 VAC !!)

What's the real news on the 91B please - and can one get one. 
I've not talked to ETO yet. First of all I'll learn from users !!

The governing factor with the 91B would be the QSK and the replacement 
price for tubes. They are supposed to be half the price of the 3CX800
so that would make them $200 or less (???)

     Hi Ward. I could not reply directly because you did not give
your email address at the end. Some of us out here are still on
ancient mainframe e-mail systems! hi.

     Your traps can be both tested and repaired quite easily.
To test them you need a functioning grid-dip meter or an MFJ
antenna analyzer with their grid-dip antenna for it.

     I have found the best way to couple to the trap using the MFJ
is to slide the stubby antenna inside the inner trap tube, and hold
the whold thing up in the air on the end of the analyzer so other
objects do not influence it. Then you will see a SLIGHT dip in the
SWR at the resonant freq of the trap. It is a very slight hardly
noticible dip depending on how well you are coupled. I suspect the
dip is easier to see using a real grid-dip meter.

     I don't have the exact trap frequencies with me, but the
inner 10 meter trap should dip around 27.5 (plus or minus a few
hundred kc, it is not critical) and the outer 15 meter trap
should have a dip around 20.3 or so, if I remember correctly.

     No doubt all your traps are full of bug stuff. Actually,
in spite of what Cushcraft says, they are easy to open and repair.
To open them, remove the end caps. Then loosen the single cover
screw, and slide the center tube up inside the trap as far as
it will go. (away from the screw end). Then stick the HANDLE of
a rubber mallet or hammer into the trap past where the screw went,
and tap the trap down against the hammer to use the handle to
drive the end insulator out the side that is not screwed in.
That will generate enough force to slip the insulator past the

points in the cover that are center punched to hold the trap together.
Do not try to pry the insulators out, it will not work, they have
to be driven out with force. To reassemble, tap the insulator
back into the trap cover with a rubber mallett.

     While inside the trap, check for corrosion at the screw
terminals on the trap inductor, and clean and debris and scorched

YOUR RESULTS MAY VARY!!! Work carefully with them, and you can fix
them yourself, although it does take the proper touch.

Good luck & 73

A while back, I read with interest, the comments on
measuring antenna gain at specific sites. While most
comments had merit, I think the point of using the least
amount of math, and concentrating on easy solutions was
It is true that you cannot mathematically calculate the
gain of an antenna for a specific ham location because there
are too many variables and unknowns in most cases. However!
Those of you who use the CDE or HyGain rotors, have the
practical solution in hand. These rotors use a dc voltage
via a variable resistor to indicate the direction of the
antenna. This voltage is perfect to use as the external
X-Axis scan signal for a spectrum analyzer. Just tap off the 
terminal on the rear of unit, have a known dBd or dBi signal
at the inner edge of the far field, such as a friend across
town with a good dipole, measure the power at the input
to the dipole, and you have a rough measurement of the
ERP in dBd. Then, the spectrum analyzer (fed by your antenna)
will draw the antenna pattern as you rotate the antenna. The
readings will be absolute values in dBm, easily calcualted into
gain, F/B, etc. Most of the stations have friends in the biz who
can provide the loan of a good spectrum analyzer.
Hope I haven't stepped outa line.  -73-

Hi Bill!

I'm happy someone out there is finding some utility in this arcane topic!  

I know of no scientific study of Beverage interaction with towers and 
large transmitting antennas; however, the anecdotal evidence suggests that 
the performance of Beverage antennas is badly degraded if such objects are 
within 1/4 to 1/2 wavelength.  My initial attempts to use Beverages were 
unsatisfactory until I placed them well away from my towers.

On the other hand, Beverage antennas are so closely coupled into the 
ground (they more closely resemble leaky feedlines than antennas!) that 
they interact with EACH OTHER very minimally.  Scientific measurements 
(as opposed to anecdotal evidence) has show that two Beverages spaced by 
twice their height (ie 12 foot spacing with 6 foot height) have better 
than 40 dB isolation.  Three foot spacing is probably inadequate, unless 
your Beverages will be very low!

Message-ID: <3031191B@arrl.org>

I remember taking a little 2 element 2 meter yagi to Central
States in 1994--it measured an astounding 7 dBd gain--though
they declined to publish the result.  Boom is roughly 8 inches.

I let them use it to probe the range (they look for a volume where
the field strength doesn't vary too much), so perhaps it wasn't
too surprising that it got a favorable reflection. By contrast,
a 3 el Kent Britain design measured 7.5 dBd and an 8 el
12 ft. W1JR measured 7.7 dBd.

Maybe a good reference is 20 dBi.    If your antennas have
that much gain you can probably make good measurements.
Measurements seem to be noticeably better at higher
frequencies (10 GHz results seem to be much more
consistent).  On the other hand, if you are 15 dB below this
reference, there is probably a great deal of uncertainty
associated with the measurement.  K1WHS of Directive
Systems, formerly of Cushcraft, has stories about how
distant trucks would disturb his efforts to measure
omnidirectional VHF antennas....

Hi Rich!

First u need to describe what you mean by "better"!

A pair of phased Beverages longer than 580 feet on 160M will produce 
narrower beamwidth, if that is what you desire...  875 feet is a good 
choice if u want to go longer than 580 feet, although the exact length is 
not critical.  As W1WCR first pointed out in his "Beverage Antenna 
Handbook," certain Beverage lengths produce a very desirable "cone of 
silence" at the rear of the antenna.  580 and 875 feet are two such 
desired lengths on 160M.  Corresponding lengths on 80M are 295 and 440 feet. 

Four phased Beverages will produce still narrower beamwidth; however, it will
be difficult to retain the excellent side rejection of the pair.  In this 
case, perhaps more is not better! 

I've always used insulated copper wire for my Beverages..  I do not plan to 
use anything else...   However, I would be interested in results with 
other types of wire.

Frank (and others) - I am a relative newcomer to the Beverage world 
(sounds like a store name, doesn't it, hi) installing Beverages only for 
2 years now. I've only used electric fence wire (17 ga). I got this idea 
from the guys at ICE. Their explanation was based on the fact that a 
Beverage is a high impedance/low current antenna, therefore little is 
lost with a few extra ohms of wire loss. Is it possible to model this? 
Any other comments from the gurus? 73 Barry

Bar, at Howard's, he set the computer clock to WWV just before the 
contest, and I noted (and remarked to him) that the clock was dead-on 
to my WWV-synched watch at the end of the contest. Perhaps something

Message-ID: <v02110100ac56a5893de8@[]>

I spoke with Chip K7JA at Yaesu today regarding the forthcoming FT-1000MP
transceiver.  I am happy to report that this looks like my dream rig -- it
has everything I like about the FT-1000 and adds virtually every feature I
felt the FT-1000 was lacking:

*  transverter port and ability to directly read out transverted frequency
(50.110, 144.200, etc.) on the VFO readout.

*  CW beat frequency will go down to 300 Hz.  The DSP audio features will
track the CW beat frequency, which will be front panel selectable (no DIP
switches on the top of the rig).

*  Quiet DDS with resolution under 1 Hz.

*  DB9 RS232 computer port (no need for level converter).

*  AC or DC operation.

*  Cascaded crystal and Collins mechanical IF filters plus DSP audio filtering.

*  Synchronous AM detection.

*  Selectable antenna jacks.

*  Separate S meters for each receiver.

*  User selectable tuning steps permitting super-slow tuning.

The FT-1000MP cannnot handle dual reception on two different bands at one
time (the FT-1000D can) and has 100w (vs 200w) output, two features I can
live without.  The FT-1000MP maintains the FT-1000's wonderful dual
VFO/tuning knob/true stereo audio operation and still has a separate RX
antenna input for Beverage use (features the new Icom rigs are notably

Chip added that the FT-1000MP front end is at least as good as the FT-1000.

Can't wait!  Anyone want to purchase my FT-1000D?

         Especially much joy was during sending QTC's. No hard paddle
         keying, no tiresome checking of dupes of QSOs and QTCs. Few
         fun cases occured with QTC asking - few QTCed guys asked QTC once
         more, after "you have 10 QTCs already" answer they were say "Nah,
         nothing like that!". The arguement "Computer doesn't mistake"
         did them to having to check their QTCs list again. Unfortunately,
         as far, as I see, v4.05 doesn't output band information onto LPT
