We are thinking of bringing in some KLV ham amplifiers but need your help in choosing the most popular ones. Please go to the following link and recommend some from the ones listed.
KLV Amps
Your help is greatly appreciated.
Thanks! |

I have the KLV-350 (two tube model)
it does about 220 max PEP on ssb.
The first 100 watts is what matters
anyway so i always run it on low.
It's one sweet little amp. |

How about the power supplies with the digital meters? |

Also the V-ULA-50 & the ULA-50-1 |

All of them!
Okay, not realistic. However, I want a KL-144 for my H-T, maybe a KL-155 for my MURS H-T. 5 watts in, 35 watts out? Works for me.
Take Care,

How about pushing some Beam Antennas too? Seems nobody pushes them anymore....your best money spent is on your antenna and getting gain both out for transmit and in for receive. I agree with Joe157 but I would fist look at my antenna and see if I could better myself there...Copper sure has many nice beams to sell but seems they push the groundplanes more.....how about like back in the days past you guys put a package together for both a beam and rotor combined and try to push some beams? You can't work'em if you can't hear'em. Way back when everyone seemed to use beam antennas and now today I see just the opposite...most use groundplan antennas and then add the amps and go 360 with all the power...how about directing your signal more first? Just wondering is all.
simple example but just an example much more complex on forumlas for those that want to get technical....short example:
A guy on AM with 4 watts on a A99 with 4db gain or 5 x power multiplier = 20 watts out (if no coax loss ..etc etc) so 20 watts out
A guy on AM with 100 watts out on a A99 with 4db gain or 5 x power multiplier = 500 wats out
A guy on AM with 4 watts on a 4 element beam with 12db or 20 x power multipler = 80 watts
A guy on AM with 100 watts on that 4 element beam is like 400 watts......seems not much different than the amp doesn't it? And you can hear better too and block out unwanted interference.
Now lets take that a step futhur and go SSB where it is usually more quite and you can use 12 watts on that 4 element beam with 20 x multiplier then you have 240 watts of legal power.
This is just a thought ...and not everyone can put up a beam and I know that but for those that can would you rather not increase both your receive and transmit?? And Copper will win either way as they have a great selection of beam antennas that go from small on a pole with a tv rotor to very very large with lots of gain and power multiplication.
Just an old CBer wondering why all the goundplanes that seem to talk out more than they can hear.

Don 123, Sounds like a good Idea but I think most Hams are using "home brew" omni antennas like quad loops etc. because of the cost factor.If Copper can get some beams for a decent price I'd like to see them too. My vote would be for a multi band HF, A 20 meter and maybe some for VHF/UHF. All the Ham beams I've seen are NOT cheap.As far as Copper's "great selection of beam antennas",I haven't seen ANY on the site.The only ones I've found are for 11 meters. Am I missing some somewhere?? |

how about the KLV 1000 they claim 700 watts,be nice to know max swing(not ssb swing either heh!! heh!!)i bet taz can relate to that!(smile) looks nice but is it clean band wise?? how well does it work with radio audio(is it tight sloopy)? in layman terms is it a diamond or crab? sixkiller505 |

Hi Hook948:
I would like to respond to your comment and hope you don't mind. First let us both agree that Copper is geared for CB/free and or 10 or 12 meter Ham operators...all the equipment they carry here is of that catergory so there is most likely no way they are interested in other bands or to have in the stock other beams for other bands (don't even sell the radios for other bands). They do however carry a good selection of 10/12 or 11 meter beams from small to very large at good prices here. My main point was to get both gain on your tx and rx and to also use beams to null out unwanted signals and noise and to first work on your antenna system as it does all the work....you can have a $1000 radio and a 800 watt amp but it will do you no good going into an antenna with no gain or receive back......it is money well spent working on the antenna system first. Your comment with Homebrew for Hams....sure that is the fun of Radio to homebrew and work with antennas...even different configurations of wires have gain! And a beam is easy to home brew....homebrew was all that one used to have. And by the way old blown down CB Beams can make a good start for other band beams. Again Copper is not geared toward other HF bands nor VHF/UHF with their product line. Your statement about Hams using omni wires on other bands like 20 meters is true....most Hams do use only cheap wires/omnis for the Ham bands...why??? Well..because the Ham bands are not like CB or 11 meters....you operate at the lowest power to make the contact not the highest therefore you can actually hear other stations not just 20 or so that want to run a kw all day and listen to themselfs or watch their watt meters....most the operators want to communicate and can do so with less wattage on a quieter Ham band...also there are not as many Hams on one band or area of a band so that helps ...so....simple antennas and low wattage will do just fine (again.....I have been in CB for over 30 years and this is a proven point...if you have a SWL receiver then listen to the 11 meter band on 1-40 ch and if the skip is in then listen to the 10, 12, or 15 meter parts of the Ham bands and you will see it has loud clear stations but no beehives.....just fact....many Hams do just that..listen on 1-40ch CB to see if 10 meter Ham band is open because it is so quiet then call CQ on 10 or 12 meters....and yep...it is open and stations come in).
Now another problem with running just beams on the Ham bands is this....most people in town do not have the space!!!! Lets face it a simple 3 element beam on 20...or 40...or 80 meter is what size....elements and boom tha is...???
here is the size:
20 meters
boom=27 feet or so
elements = 35 to 31 feet
40 meters
boom= 51 feet
elements =70 to 62 feet
80 meters
boom = 96 feet
elements = 131 to 118 feet
So most of us just can not run beams that big...no space...and many times just too much money for that big of antenna structure. So yes multiple band wires and verticals are used often...and work well too!
But on 10 or CB/11 meters you still can put up a good gain antenna with smaller sizes and get gain!!!
BTW....made a nice 12 and 17 warc band beam from a Copper Maco M103....was great for starter parts and you just have to add to the elements and the like.....so for 99 bucks not bad!
And antennas are fun so by all means experiment and homebrew...here is a 2 elment 10 or 11/CB beam anyone can make and it will give you gain......link:

Forummaster,
I am interested in a couple of KLV's VHF amps. However I'm looking for an affordable 6 meter amp and KLV does not really make one (their's operates below 50 mhz).
