Re: [Elecraft] Small HF amp suggestions
Hi All, I just read the post by Bill Schmidt, K9HZ, who defended the RM Italy "HLA series" amps as not being as bad as many folks seem to think. I had posted a similar response earlier, but thought I should add some substance to my defense (and perhaps to Bill's). I think much of the confusion stems from the fact that RM Italy makes several different series amps. Some were apparently only intended to be single band amps (CB perhaps?) and did not have very effective filtering. However, the "HLA" series amps are intended to cover multiple bands, and do have decent filtering. I own an HLA-150 amp, and have found it to be a decent performer, although it does have lots of deficiencies. As I said in my earlier post, Tom Rausch, W8JI, made some extensive tests of that same model amp, and though he found some serious issues, he defends the amp's adequacy when operated conservatively--that mainly being to not run it much above 90 to 100 watts output. Hopefully most of you are familiar with W8JI, who has considerable credentials in the ham community regarding amplifiers (he designed many of the more popular amps being used today), and is very knowledgeable on other topics as well. Anyway, here is a link to Tom's website wherein he discusses the pros and cons of the HLA-150. You might want to take a peek at it. http://www.w8ji.com/rm_hla-150_test.htm I'm not suggesting that this amp is a great piece of gear, or the equivalent to new stuff coming out currently--just that it might be usable, and not nearly as inadequate as some would suggest. I also think there are many other choices, including the upcoming Elecraft amp, which would undoubtedly be a better choice. However, I got my HLA-150 pretty cheap (used), and I think they tend to be sold at fairly low prices on the used market, which might make them attractive--at least as an interim choice--while you wait for some of the newer ones to become available. Just a few watts will drive an HLA-150 to 100 watts plus. The amp is auto band switching, which is a very handy feature. It is moderate in size and weight. Supposedly it will work just by using RF sensing, but I have found that to be problematic. On CW the amp seems to cut off the first dit or dah, so it really needs to be used with a keying line from the transceiver. Also, it's not really a QSK amp, and that is a big deficiency in my view. You can bet the Elecraft amp will have good QSK, and I think the new Ten-Tec 418 amp does as well. The HLA-150 doesn't purport to cover 6 meters either, and that is another issue which other alternatives will solve. I doubt 60 meters is covered by the HLA-150, but the Elecraft amp will cover 60 meters, as will the new Elecraft amp. Personally, I'm a little reticent about the Ten-Tec 418 amp for various reasons. I'm not so sure they didn't "overcook" it a bit. First of all, it looks too big. It's twice the size of my HLA-150 (and HL50-B), and weighs twice as much. Is that necessary? All I've seen of the new Elecraft amp is a picture, but it looks more reasonable--and practical. The Ten-Tec 418 incorporates, among other things, a big LCD display, and two fans--things I wouldn't have thought were necessary in a small amp, but maybe they are. I still have an old Ten-Tec 405 linear, which will run 50 watts+, and is less than half the size and weight of the 418, no fans, but has power and SWR metering included. It still works FB too, even after 30+ years! Apparently the new Ten-Tec amp covers 60 meters, but initially I don't think it was going to. By the way, the new Ten-Tec QRP rig doesn't cover 60 meters or 12 meters, and I think their amp was originally going to skip these bands as well. I'm genuinely confused by Ten-Tec's omission of these bands, but that's another issue. So, if you are just looking for something reasonably affordable to boost your QRP rig a couple of S units, and not too concerned about "bells and whistles", then the HLA-150 might be a good option--at least in the interim. I certainly wouldn't expect many of you to just take my word for it, but I think W8JI's discussion is more convincing. Sooner or later though, most of us will probably yearn for the kinds of features and capabilities that the new Elecraft amp will undoubtedly offer. For versatility I ultimately want a small amp that has good QSK, and when I want to use it with some of my simpler QRP rigs, I'd like to have good, effective RF sensing (hopefully that's a reasonable expectation). I also want it to cover ALL of the bands through 6 meters. If the new Elecraft amp does all of this, and at a reasonable price, I'll probably get one. I can unload the HLA-150, and my THP HL50-B, and probably not be out of pocket much, if anything. Well, I might have to look around for something else to unload as well, but hopefully it won't be a problem. The new Ten-Tec amp is pretty expensive in my view. 8 bucks a watt

Re: [Elecraft] Small HF amp suggestions
I take issue with this... There are several different RM lines... and models within the lines to select from. I own one of the HLA series amps that, in fact, has a reasonable output filter (by band)... and produces 100 watts from 1.8 watts input and plenty of head-room as not to flat-top and cause distortion/splatter.

Re: [Elecraft] Small HF amp suggestions
Hi All, I have a RM Italy HLA150, but I haven't tried it yet with the KX3. I've been using another amp, the THP HL50B, which works quite well. Not QSK though. It has good RF sensing, and gives me abut 60 watts or a bit more. It isn't auto band-switching either, but otherwise it has been an excellent performer for me with all sorts of different QRP rigs. The HLA-150 I have works O.K., but it really needs to be hard wired to the rig, rather than trying to rely on RF sensing. That's a problem for some of my QRP rigs because they don't have provision for keying an amp. That's why I tend to use the HL50-B. The biggest problem I've heard about, with regard to the HLA-150, is that if you run it much over 100 watts it tends to get "dirty". W8JI wrote a lengthy analysis of this amp, and seemed to think it was O.K. otherwise. It is auto band-switching, which is nice. So, I wouldn't be too concerned about that amp so long as you use it prudently. Some RM Italy products get a bad name, mainly because they don't have effective band filtering, but the HLA series does. A friend of mine "field tested" one of the new Ten-Tec amps and liked it. I think it's a little expensive, but it seems to have a lot of features. I have no doubt that the yet-to-be-released Elecraft amp will be a very good option. The delay in production tells me that Elecraft is probably trying to pack every feature they can into the package. Obviously it will be very easy to mate with the KX3. We don't know the price yet. Hope it's not too much. I have to wonder if Elecraft isn't re-working their offering after seeing what Ten-Tec was putting out. There are a lot of features on the Ten-Tec amp that don't seem like they would be included in Elecraft's amp, based just on the preliminary picture of it. But then again, maybe they are planning on a somewhat simpler, but effective product at a lower price?? >From the picture, the Elecraft amp seems more comparable to the THP type amp. There is such a vacuum of information, I don't know what to expect, except I'm sure it will be a very good product. Other small amps you might consider include the HF Packer Amp, which has gone through a number of feature upgrades over time. It doesn't put out as much power though. Also, the old Ten-Tec 405 linear is a good choice if you can find one. The biggest problem with those is that they are annoying due to relay chatter. I bet that could be modified. Those will easily put out 50 watts or more. I'm not sure it will cover the WARC bands. So, lots of choices out there. I'd probably wait to see just what Elecraft comes out with before I made a serious acquisition. For now I'm happy with my HL50-B. If I like what I see from Elecraft, I can probably cover a good portion of the cost by selling that one. For that matter, I've probably got a few other things around here I could unload and maybe end up not being "out-of-pocket" much, if anything.

Not at all like common VHF amps, which are generally designed for one band, and can often use printed circuit elements for inductors, etc. And, many of those amps are designed for FM use, and are not linear amps. So, I'd expect a reasonable amp to cost a good fraction of the price of a rig... like 50% or more. I'll wager that the KXPA3 will price in at $600 at least.

Re: [Elecraft] Small HF amp suggestions
Take a look at this site: http://www.n2ckh.com/fl110.htm These show up from time to time. My little QRP circle of friends have found 2 in the last month. Both were around $300. When you see a solid state amp that was built in the late 70's with the original output transistors, you get the feeling it was put together correctly. The amp can actually take up to 15 watts in, and can develop higher output than the 110 watt advertised output. I believe it has a 200 watt PA potential. The Tokyo HL50 (forerunner to the HL45) can be purchased in the 350 - 400 price range. If you have to order one new, and pay shipping, it can become cost prohibitive. You can always go the Metron route, and have up to 1K watts; if you have enough battery and charging system.

Re: [Elecraft] Small HF amp suggestions
That's a little steep for a mobile amp I think. I'm sure it's a good quality amp but I only want up to 200 watts max for mobile use. I may be out of touch, but I think ~$2/watt should produce a reliable amp of less than 200 watts. God Bless & 73!

Re: [Elecraft] Small HF amp suggestions
Yes, I used one years ago with my K2 before the KPA100 was available. CW only with marginal success. SSB had RF/audio issues that I chased for quite a while with no success other than adding a lot of various RFI devices to my 'junque' box once the KPA100 was added to the K2. 73, Roger K7SJ/VE1 Halifax, NS K3 # 75 Sent from my iPhone On 2012-11-07, at 10:17 AM, va3...@gmail.com wrote: > Does anyone else have any experience with this amp? > a 'kosher ham' > > Robert > > -Original Message- > From: Keith Heimbold > Sender: elecraft-boun...@mailman.qth.net > Date: Tue, 6 Nov 2012 19:17:02 > To: Jack Berry > Cc: elecraft@mailman.qth.net; > > Subject: Re: [Elecraft] Small HF amp suggestions > > I would be careful with the RM Italy amps.

Re: [Elecraft] Small HF amp suggestions
Thanks for the responses. Looks like RM Italy is an option for mobiling with the KX3 and a mid range power boost. All others seem to weigh in too heavily in power and cost. Unless a KPA100 is available sooner than expected, will either delay the KX3 or pick up the RM Italy.
