Yes, a 2m amp from Electraft would be desireable.

I own a KX3 with the 2-meter option and I have considered buying a 2-meter amplifier in the 35 to 90 watt power range (or, something close to that). But, I would rather have an Elecraft product. Do others feel the same way or am I wanting too much? 73, phil, K7PEH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

My feeling is that unless an acceptable design or product could be re-branded, the total sales potential would never justify the engineering effort.
Just ask yourself, of all the K3's and K3S' sold, how many have the internal 2M option installed. Of that percentage, how many need an outboard amp. From THAT percentage, how many either already have one * or how many will buy a "pre-owned" amp? I'd bet the answer is "Not a lot".

My experience on VHF is 10 to 20 watts and a 10 ele yagi is OK for most
CW and SSB work when good tropo conditions exist. However, more antenna in the air will help on both receive and transmit and be to more advantage to all as opposed to 100 to 200 watts alone. 73 Bob, K4TAX K3S s/n 10,163 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Try this: Chris at the Metalwerks. You can reach him anytime at
801-231-2658 or by email Chris at KF7P dot com. I have used him for
a number of projects and can vouch for the quality of workmanship
and timeliness of delivery. He probably still has the set of
drawings that I sent him for the enclosure.

Your experience would be quite different west of the Mississippi, where population density is much less, and with much greater distances between population centers. That's why, for example, the FCC licenses 10 dB greater TX power west of the MS river. Higher TX power also helps for moonbounce and meteor scatter. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Yes well, as to EME and MS, my viewpoint is anything less than legal
limit is considered QRP. Which brings a point to mind. I get really annoyed with stations adding a power amp and doing nothing to improve their receiving situation. Seems hams like to have folks brag on their big signal when their receiving conditions are as deaf as an anvil. 73 Bob, K4TAX K3S s/n 10,163 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Crafting a case very similar to the one pictured on the sited page is relatively easy. While I do have a brake and no problem crafting cases I will tell you how I would do it without major tools. 1. Do a drawing of the case with sizes and flanges laid out piece by piece; top, bottom, sides, ends, etc. 2. Locate the nearest Metal Supermarket. I use them as they are close and reasonable and I know them and their stock. They will cut your metal pieces to size very cheaply. Often free. 3. Contact them for a quote and order. They may mail your order, I do not know. There are other places who do the same type business; small orders with cutting. 4. Cut 2 hardwood blocks that just fits inside the lines of the front and rear panels. They should be smaller by the thickness of the metal material plus a smidgeon. 5. Carefully fit the blocks within the lines of the panel you are bending and clamp in a vice. The blocks should be aligned as well as with in the panel lines; Use double sided tape if necessary. 6. Use another hardwood block as a "push block" and gently push and hammer against the flange all along its length until it is bent 90 deg. bending only a small part of the angle at a time. 7. The blocks are also useful when drilling the holes. Some may prefer to drill first but that makes hole alignment very difficult.

I built that W6PQL 80 watt amp last year. Built the aluminum chassis, too. I did not have a sheet metal brake, but a few minutes on Google turned up quite a few home-brew brake plans. I built one of them and used it to form the chassis for my amp, and later on a couple other small boxes for shack utility projects. If you enjoy building stuff, creating your own brake is worth the effort. I think I made mine for less than $25. And it works pretty darn well!

Harbor Freight sells an 18” sheet metal brake for about forty bucks.
I’ve used a lot of Harbor Freight tools. Some of them require a bit of tweaking to work perfectly, but they’re generally good enough right out of the box.

I have analyzed my costs to build single units of the W6PQL 80w 2m
amplifier and the total material costs come to $254. Based on that I have posted information at: http://www.kl7uw.com/kits.htm The amplifier will use a 1.375x5.375x8 inch heat sink with a 120mm fan. Fan will be thermistor controlled. The enclosure chosen is the Hammond 1590D 4.7x7.4 inch diecast aluminum box. It will be available in natural aluminum or painted a light flat gray. A ten-segment LED RF power indicator will be included. Otherwise is as described on the W6PQL website (link from my website). It will be offered as a partial kit (all surface-mount components pre-installed but all thru-hole left to the customer). Price $284.00 + $18 flat-rate shipping & insurance Also available fully assembled and tested for $354 + $18 flat-rate shipping & insurance Optional N female connectors for additional $5.00. All prices in US funds and subject to change without notice and only apply in the USA. I will ship international but shipping will be more. NO ORDERS accepted until November, 2015. E-mail me if you want to be put on a pre-order waiting list. PayPal will be preferred method of payment. These will be built one at a time with my 30-day delivery policy. 90-day warrantee on labor and materials. Input power range 50mw to 10w which must be stated with order. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Most metal houses will shear stuff to size for a small pittance. A
desktop drill press for drilling holes, Bob's your uncle....Case parts. Being a semi-retired production and R+D welder, and having a pretty nice Mig/Tig setup just begging to melt some metal, it wouldn't take me long to tig weld an aluminum case. Look Ma! Very few screws! I count four to hold the heat sink in the case, maybe six, and whatever the number is to attach an N style chassis connector. -- R.

Built the aluminum chassis, too. I did not have a sheet metal brake, but a few minutes on Google turned up quite a few home-brew brake plans. I built one of them and used it to form the chassis for my amp, and later on a couple other small boxes for shack utility projects. If you enjoy building stuff, creating your own brake is worth the effort. I think I made mine for less than $25. And it works pretty darn well! >> >> Jim / W6JHB >> >> >>> On Tuesday, Sep 22, 2015, at Tuesday, 10:47 AM, P.J.Hicks <[hidden email]> wrote: >>> >>> >>> >>> Crafting a case very similar to the one pictured on the sited page is relatively easy.
