An 8 ohms speaker will work fine and will have less distortion
and generally better fidelity but will not be quiet as loud as a 4 ohm.
You could parallel two of these 8 ohm speakers for the 4 ohm load.
You might consider using some of the little amplified analog
speakers that or made for computers.  Some, in the 35 to 50 dollar
range, are very nice with their on amplifier, having volume and bass
treble controls with a bass speaker and two small satellite speakers.
They come with a mini stereo connector for connecting to a computers
audio output but the connector can be cut off and the two stereo coaxial
lines tied in parallel for mono operation.  You could just plug it in
too a mini female connector and wire the female connector to the HQ110
audio output or get an adapter that will go from the mono head phone
jack on the radio to the mini stereo male connector of the speakers.
The input impedance on these speakers in generally in the my range of
1000 ohms so they want produce much of a load on the radio's output and
this will improve the fidelity of the output section of the radio.  A
lot of time, the cheep speakers in the twenty dollar or less range
actually make better communication speakers and will produce less hum
because of their poor low frequency response.  Some of the real cheep
ones or not stereo, even though there or two speakers and a stereo
connector but they are amplified.  These can be purchased for less that
ten dollars and work quiet well for communication speakers but not for
fidelity in frequency response.

Good Luck

John

Was wandering if I could get a few suggestions on an External

and Hammarlund HQ-110A. The only Hammarlund speaker I could find was
worth more I guess then I payed for the receiver. Anyways was wandering
what some of you guys are useing that are not useing matching speakers
for there receivers. Also the Hammarlund calls for 4 ohm speaker and was
wandering if the audio fidelty would still be OK useing an 8 ohm speaker
of some sort?

Re: [AMRadio] Antenna slip up mast

[Rev. Don Sanders]

I installed mine using a 4 foot piece of plastic pipe with 3 foot in the
ground. Dug hole with post hole digger. 1 foot above ground was inserted
inside bottom of mast about 6 inches. Drilled hole thru pipe using the
existing hole in bottom of mast. Installed a long bolt thru hole in mast
bottom and pipe. installed two nuts on bolt. Mast is held on 4X4 post
supporting the edge of the roof over my shack using a Rad Shack vent pipe
mast clamp. Very solid and easily removed for additional work. Standing on
the roof, easily pushed up by one person and secured by large cotter pin in
hole at each pipe top and adjustable hose clamp on each section just above
the top of the next lower section. Vhf antennas at top of 40 foot section
and
one corner of the 40 meter horiz loop at the 30 foot level using a pully and
support rope. Two guys of rope at the 30 foot level opposite the loop
antenna.

Healthfully yours,

Re: [AMRadio] Slip up mast for 80 meter antenna

[Donald Chester]

The last time I bought one of these was a few years ago to hold up my 10m 
ground plane.  I think I got mine at the local electronics supply store.


Rohn used to sell some very nice heavily galvanised heavy duty ones, but 
since they went out of business I am not sure if whoever is still selling 
their product offers them.


I used to make a 1/4 wave 80m mast by adding two standard 10' tv masts to 
the top of a 50 footer.  The 50 footer actually only extended up 45' because 
some height was lost where the sections telescope together.  Two more 10' 
sections on top made the whole thing a little over 60' tall.  It took a crew 
of people to raise the thing, though.  One slipup and you have a giant steel 
pretzel to dispose of.


The declining use of over-the-air tv reception, especially if the tv 
stations are all forced to go digital in a couple of years, will likely make 
telescoping tv masts as rare and hard to find as triode transmitting tubes.

Re: [AMRadio] Antenna slip up mast

[John Lawson]

An installation using a Lowe's telescoping mast:

  I'm using one for my VHF/UHF stick (Diamond) - I dug a 4' deep 30" round 
hole (the hardest part of the Job) for the base. I got a 5' piece of 
pre-threaded 1 3/4"(IIRC - it has to just fit into the bottom section of 
the mast) pipe and a couple of bags of "quickcrete" - the fast-setting 
cement meant for fence posts and the like. I cut a foot off one end of the 
pipe, and put the remaining 4' in the hole, threaded end up, with 6" or so 
above grade, tacked it to a 2x4 to keep it vertical and plumb (used a 
plumb-bob: real hi-tech here). Dumped in the concrete mix, poured in the 
required amount of water (abt 3 gallons) and went off to find lunch. 
Returning from lunch, I got busy mounting the Antennae (and weather 
station senders, and a DishTV dish) to the mast. I also used some 
stainless steel hose clamps to 'assist' the rather cheap set-screw type 
mast section clamps.


  After a couple of hours, the concrete had set up completly. I threaded a 
standard 'pipe union' (female, or large portion) onto the top of the pipe. 
(Note to self: next time use lots of Loctite or similar - I had to drill 
and pin the threads later, to keep it from turning).


  I cut a slit across the bottom of the mast, forced the previously cut 
off end of the threaded pipe into the mast (threads down), then drilled 
and pinned the whole thing with a stainless 10-24 bolt and nut assembly, 
and finished it with a pair of large stainless hose clamps.


  Now, the 'female' side of the pipe union goes on the base-pipe, and the 
'male' section gets threaded onto the mast. (Note to self: next time, 
Loctite, dammit!)  The mast goes up in the air, in my case gets clamped to 
the second-story eaves with electrician's pipe clamps - et voila, c'est 
fini.


   When it comes time to take it down, for additions, repairs, etc - just 
loosen the top clamps and un-do the pipe union at the base - couldn't be 
easier!


  It has been up there going on three years now, through the worst that 
northwestern Nevada has to throw at it (80 mph + winds, t-storms, snow, 
rain, summer 110 degrees) and so far, no signs of needing any TLC.


  Whole cost (not counting antennas, etc) was about $75 and four or so 
hours.  Like I said, the worst part for me was digging the damn hole - 
Your Milage May Vary.

[AMRadio] Antenna slip up mast

[w6om]

Thanks to everyone, once again the AM fraternity has come through. Lowes is the 
place and I am on the way to pick one up now.

It is amazing how through the years this group lead me through restoring a 
NC-300, NC-173, DX-100, Valiant and Ranger. I would not be enjoying AM Radio if 
it
were not for all your suggestions, recommendations and frienship.

73 to all and thank you

when you see the stripe, stop and insert the 1/4" cotter pin. You can
make a base from 2 each 6" lengths of angle iron with a bolt through them
and the bottom of the outside section. Good luck.



the problem with that method, I've found Ed, is that when the sections 
are banging together in the
wind, and they're not secure from one section to another, they tend to 
create static and noise in
the reciever.  Much better performance from Push-up masts, when they're 
'solid', and well grounded.


EMT is a great idea, but I think those joints that are threaded on each 
end would make better support
structures. 
Easy steps (as I see it)

1) get someone to help.
2) Put two sections together for 20'
3) attach a pully w/rope to the top of the sections
4) stand them up against the house/garage
5) loosely fasten a clamp around the pole against the structure you're 
mounting it to

6) push up the existing sections and insert the next one from the bottom.

How high you want to go, depends on how many sections you decide you need

Personally, my experience has been that dipole antennas work better when 
they're

1/4 length (or better) above ground, for the frequency you're operating.

1/4w on 75m is roughly 60'.  Even if you can't 'flat-top' the antenna, 
at least the apex,

or highest point of the antenna should be that far above ground.

Just my .02c worth.  No change needed. Your mileage may vary.

[AMRadio] HQ110A speaker

[VJB]

Herb,
The best audio quality on that Hammarlund comes when
you pre-set the audio output of the HQ-110A so that
the AF circuitry is not "adjusting" the tone as
designed.

I have an HQ-100AC and found that the lower volume
settings and the higher volume settings include
different emphasis between bass and treble, a
deliberate compensation circuit.

I find the sweet spot in the audio output level where
the response is "flat" or unaffected by this
compensation, and then drive an external audio
amplifier and a hi-fi speaker (like you'd use on your
home stereo). The external amp, which can be as simple
as a $40 yard sale stereo, gives you all the volume
control you'd need, and can provide tone controls for
bass and treble to suit your taste.  Using such a
setup also typically provides an output to make a
recording.

Regards

Paul/VJB
