I have both the Array Solutions "Power Master" and the ALPHA-4510 POWER/SWR and I find myself using it in conjunction with my ALPHA-9500. Since the "Power Master" will handle 6M up to 2KW, I use it when on 6M running a modified SB-221 that will put out Full Legal Limit; but, I normally run it at 1KW PEP.
Take a look at the features of the ALPHA-4510, I think you will really like it.
Alpha 4510 3KW Wattmeter QRP TO QRO. Our Wattmeters can measure from 200 milliwatts full scale to 3 kilowatts full scale, from 160 meters to 10 meters with no slugs!
The Alpha 4510, 3KW Wattmeter represents a revolution in RF power measurement. State of the art integrated circuit technology and innovative design techniques have combined to deliver a mix of features, precision and convenience previously only found in a laboratory-grade power meter. During operation, the 4510 simultaneously measures the frequency of the signal and the internal temperature of the unit, and compensates for those factors in determining measured power. This assures linearity in the accuracy of measured power under changing operating conditions. Internal calibration errors are also further reduced by use of proprietary sampling and differencing techniques.
The 4510 outputs all data to your PC via a serial cable and with the Alpha Wattmeter software allows you to monitor forward power, SWR and reflected power simultaneously. Price: $745.00

eHam Forums / Amplifiers / RE: Choosing a Legal Limit Amp

Currently, I have 4 amplifiers. The AL-811, a Heathkit SB-220 a converted SB-221 to 6M and an Alpha-9500 with an Alpha-4510 Power/SWR Meter which I have had for the past year and a half. Before Alpha-9500, I had an Alpha-87A for about 3 years. At this point, I have to force myself to use one of my other amps, otherwise, I would never turn on anything except the Alpha-9500; it is a sweet machine to operate. The Alpha-9500 couldn't be easier to operate. All you have to do is select the band on your Exciter, reduce power to about 15 watts out of the exciter, press the "Auto" button on the Alpha-9500, send a continuous wave signal from the exciter, bring up the exciter power to about 42 watts and you will be at 1500 watts PEP when you switch to SSB. Turn off the "Auto" feature of the Alpha-9500 and begin to call CQ. I know of some operators that tune/load their systems using the Alpha-9500 without starting out with low power, they set their exciter to about 45 - 50 watts and start talking SSB and let the firmware tune the Alpha-9500; personally, I don't see any reason to stress a piece of equipment just because it will take it. I don't think you can find a better automatic tuning RF amplifier for the money anyplace. It is my opinion that the Alpha-9500 is a lot sweeter tuning amplifier than the Alpha-87A; but, that is just one Old Man's opinion.
Good luck with the decision on the amplifer you finally decide to acquire.

I too have a Mosley CL-33 on the ground at this time that I intend to restore; so, any information as to the best method there is to be used in refurbishing the traps that will have a long life span between repairs. Your time and consideration is greatly appreciated.

The English grammar rules are there to be used by those that desire their works to be admired and given credit. After perusing over the first two paragraphs of his work, I too wondered how much credit could be attributed to the technical portion of his writings after noticing his terrible attempt at the use of English Grammar.
As he did, I too graduate from High School and after attending schools of higher learning for 9.5 years, I attained a Terminal Degree in Mathematics, which required writing a dissertation and defending it before a Major Professor and three of his collages. At one time, I did possess the skills to correctly write the English Language; but over the years of hearing the English Language “butchered” by the so-called educated, I too have become lax in my writings habits. However, I haven’t deteriorated so far in my old age so as to try to begin to understand your misuse of the rules of English grammar.
Just because you don’t ascribe to the current rules in writing the English language and follow the established rules of grammar that I will change enough to accept your kludge of words and their meaning.
Think about this, what would our "written word" look like today if everyone that were to write an article decided to use sentence structure that “Sounds Good to Him”, in the article he wrote. That is one of the main reasons that people don’t speak and write the English Language correctly is because they have heard it “butchered” to death by those that don’t know how to correctly use it.
I bid you the best of luck in your writings and that you attain whatever it is that you aspire to be.

eHam Forums / Computers And Software / RE: What routers are Ham's using that are RFI FREE

At my installation, I have a a Netgear wireless router with two devices attached to it by CAT-5 cable about 5 feet each to two different printer devices which are on the Network. On the Wireless side of the Wireless Router, I have 4 computers which use it, with two of them in my Ham Shack and I haven't experienced and RFI problems from it. The current configuration in my Shack has been static over the past three years with 2 HF Transceivers, 4 VHF/UFH Transceivers, 3 HF and 1 6M Amplifier and associated power supplies, antenna tuners, etc. and associated Ham equipment. The Wireless Route employeed here is the NETGEAR 54 Mpbs Wireless Router Model WGR614 v6; 54 Mbps, 2.4 GHz, 802.11. So far, I have been very lucky that the Local LAN, both the Wired Network of printers and the Wireless LAN of the 4 PCs. Hope this may be of some help to those that are having RFI Problems with their home networks.
