  • This videos gives my thoughts/opinions on 5 QRP radios: the CRK-10A, MFJ-9296, MTR3B, MTR5B, and KX2. This is a follow-up video to one I made last year that covered 5 QRP radios: the FT-817, Flex-1500, KX1, K1, and KX3.

    Hi Cliff, Thanks for your message in regard to which KX model you would buy if you were buying today and the reasons why. I can't seem to find your message, so I'm sending a thanks in here. My wife wants me to stop watching your video's. I buy something every time I do. I now have a flex 6300 and despite all the noise out there lately......wow! What a radio. Looking forward to using the SOTAbeams 20/40 antenna as soon as the weather gets a bit better here in upstate NY. No need to mention other purchases......haha. I appreciate your time and dedication to putting videos up for us all. 73 KD2LMR

    I scored a MFJ-9200 and a couple of band modules at a local swapmeet for $120.00, how do I know if its a 9296? Do they all say 9200? Confused

    • @QRPSchool
      @QRPSchool  8 років тому

      Hello. I believe that the 9296 is the MJF model number of the 9200 radio that already includes all of the bands. So, they are the same radio. - Cliff

    Nice informative video. You forgot to mention that the KX2 DOES in fact have an internal mic. You can use that little radio like an HT with the use of the built in mic. I have a loaded KX2 and I feel it's one of the best values in QRP. A tad expensive but well worth every penny spent on it. I even have the internal clock option and use it all of the time so when I paper log (portable operations) I know exactly what time it is.

    Great video! Thanks, Cliff. You forgot to mention that the KX2 has a built in mic for the inevitable day you land up on a SOTA peak and find you have left your usual mic at home :) Works fine as well. Also a nice new mini paddle that attaches to the base.
    Note, the KX2 has contest quality RX/TX, and is a full SDR. Truly, with the built-in battery and ATU, it is the most self-contained CW/SSB/Data HF-8 band rig around. 73 John, N6JW

    • @QRPSchool
      @QRPSchool  8 років тому +1

      Hello, John. You know, I even took a picture of the microphone hole and meant to mention it. That's what I get for shooting unscripted videos!
      For anyone who reads this: The KX2 has a built-in microphone that can be used in emergencies and/or if you want to hold the radio like a walkie-talkie. You can even use a whip antenna with a trailing counterpoise connected to a mini-banana jack, just for that purpose. If this appeals to you, look up "manpack ham radio" and you'll find websites about radio nerds (no disrespect intended) walking around making contacts on HF. - Cliff

    I am surprised you didn't mention the mcHF (designed by m0nka, available as a kit), or the Xiegu X1M-Pro (which I heard has been recently discontinued), or the Xiegu XM108. The mcHF is especially nice, as it is about the same size as the Elecraft KX2 but has a color touchscreen, AM and FM capability as well as SSB, CW, and data (CAT control available via USB cable, use Yaesu FT817 command set). Not exactly a "plug-and-play" radio, as a number of mods should be done for best performance, but there is a very good support group on Yahoo covering those mods. Firmware is open-source and is constantly being improved and updated. de KC8MWG

    Although the 9296 is no longer available, a few band modules are. One thing I think is important, is to put some sort of tape on the chassis above the position where the band module sits, to protect it from shorting to the chassis if it is slightly ajar.

    Hi Cliff, I love your videos!! How do you rate the KX2 compared with the KX3 after some time with it now? I would like to buy an 817/KX2/KX3 but can't buy them all because the wife will not be understanding! ;-) If you were to buy one, which would you choose? I would be taking it on vacation/weekends away in a portable situation. Don't mind carrying a separate battery if needed.
    Kind regards,

    • @QRPSchool
      @QRPSchool  7 років тому +2

      Simon,
      I've hardly touched my KX3 since I got the KX2. I recommend you purchase the KX2 if you DON"T CARE about these features - that are only available on the KX3...
      - Optional Roofing Filter (good for when you're working NEAR another ham)
      - 160m & 6m
      - Optional Panadapter
      - Optional 2m/4m VHF coverage
      - Weighted tuning knob
      I don't care about any of those things in a portable radio so the KX2 is a great choice for me. That said, I will keep my KX3 for in-shack use. It IS the state-of-the-art in portable QRP radios.
      You really can't go wrong, either way! - Cliff

      For Elecraft. you might be able to find a used K1 or KX1. The K2 kit is still available and the base model is CW only. However, it's a fairly serious kit. You might consider an LNR Precision Mountain Topper... www.lnrprecision.com/store/Transceivers-c10468544

    • @322doug
      @322doug 8 років тому

      reason i asked, is i'm looking at that LNR site, the antenna u suggested is now back in stock, so i also started looking at the mountain toppers, so was just tweaking my final decision between the MFJ, and say the MTR5B, trying to figure if the xtra $150 for the MTR5B was worth it or not, if the signal is considerably clearer i think might be better for me. I have a lil hearing loss from my time in the military.

      The Elecraft KX2 has to be at the top of the list for me. The internal Lithium Ion battery pack and internal antenna tuner make it self-contained. You can do CW, SSB, and Digital modes with it. And it’s packed with features. All of the other radios are fun but the KX2 is the best size/features/performance combo in my opinion. What are your thoughts? -Cliff (N4CCB)

    and can u suggest any transceiver kit builds, i seen one online that a guy built , and i got to give it a try, my electronic knowledge and skills are probably above average, and that would be awesome to actually build a CW transceiver radio, that i could use. so , plz , if you have any suggestions, let me know, i would greatly appreciate it. I am looking to see if there are any radio clubs in my area , so i can stop bothering u with all these questions man, but you have to be the most reliable and practical source i have come across , and u r always spot on.and i cant remember if i thanked you for ur dmm suggestion it was perfect, and i ordered the EXTECH from amazon.so THANKS! and alot cheaper than the fluke i was looking at.

If you want to spend less at this time, a simple 7Ah SLA battery will do the trick! You'll be able to transmit morse code all day with a QRP radio using a battery like this: www.amazon.com/ExpertPower-EXP1270-Rechargeable-Lead-Battery/dp/B003S1RQ2S/ref=sr_1_1?ie=UTF8&qid=1469026294&sr=8-1&keywords=7ah+battery

    @user-ss6zt2mo1l 6 років тому

    Quick question ! I run a homebuilt magloop antenna (36” across)for 40-10meters, is it possible with these little radios (MountainTopper) to hear the “peak” of the matching capacitor when trying to find a match?
    I built a Norcal 40 that i cannot peak tune to the resonant frequency.

    • @QRPSchool
      @QRPSchool  6 років тому +1

      Yes, you should be able to use the magloop with a QRP radio the same as with any radio. Go for it. While I'm here, I have to tell you that using a 36" magloop on 40 meters will put you into QRPp teritory. Loops of that size are great for 20m and up.
      But, for 40 meters your 5 watts will turn in to a few hundred milliwatts. It's just physics... the size of the loop is so small compared to the wavelength of the lower bands. This warning is not from me... it's from an article I read from a couple of PhD's who wrote an article about using the AlexLoop. They graphed the efficiency and it just plumments when you drop below 20 meters. - Cliff

    • @user-ss6zt2mo1l
      @user-ss6zt2mo1l 6 років тому

      QRP School I know. Its only like 7% efficiency on 40. I built it to actually work with my SDRPlay receiver. It actually tunes from about 5600-22000. I just started teaching a group of Homeschool kids about Amateur Radio. I am trying to get them excited about Radio. Its easier to lug this thing around vs a full size antenna. I did build it with a 6Kv transmitting capacitor. I have run it with my 7300 but only briefly. My Norcal 40 (the pre-kit version) will not peak on receive with the loop. Im looking for a small portable radio I can bring to class and demonstrate to the kids cw/ssb. Im looking at the Elecraft KX2. Its sooo nice.

Would you be able to give any suggestions as far as antennas, something i could maybe hike with, im guessing 40 m maybe.

    • @QRPSchool
      @QRPSchool  8 років тому

      If you'd like to purchase a commercial antenna for hiking - or just want a very compact antenna - I would recommend the LNR Precision 10/20/40 End Fed Half Wave antenna. During the day, you'll want 20 meters. In the evenings, you'll want 40 meters. This little antenna will work on both of those bands. I have it and it works great.

    • @QRPSchool
      @QRPSchool  7 років тому

      There's "Best" and there's "Plenty Good Enough". The KX3/KX2 would be in my "Best" list. If you care about all modes, I'd go with the KX2 since it's significantly smaller than the KX3. All other radios (except the single frequency rigs with wide bandwidth) are plenty good enough.
      The KX1, if you can find one, is a fantastic little rig that was designed for hiking/backpacking. But you should definitely check out the LNR Precision Mountain Toppers. They are pocket-sized - although you'll need an external battery. You may want to consider using a battery pack like those used in RC model cars to keep the package small. (The KX2 has a nice internal Lithium Ion battery pack, btw.) - Cliff

      Welcome to the wide world of ham radio. There's a lot of information that you need to get up-to-speed on... more than I can send by typing. It would be best if you could join a local amateur radio club and meet some other hams who could talk with you in-person. You might also want to take a look at the ARRL.org online bookstore which has books for hams of every level. This one is recommended for hams that want to set up their first HF radio station: www.arrl.org/shop/Your-First-Amateur-Radio-HF-Station/

    • @QRPSchool
      @QRPSchool  7 років тому +2

      Hello, Dave. You can connect the KX2 to your computer and use any digital mode software. As a matter of fact, you can connect ANY HF radio that can transmit SSB (voice mode) to your computer and do digital modes. I use a Signalink box for this purpose.
      The KX2/KX3 also have the ability to decode PSK31 and RTTY without a computer. And, if you send morse code using paddles, the radio will encode your morse code to PSK31 or RTTY. This allows you to send/receive PSK31 and RTTY without having to take a computer with you into the field. However, I'm (relatively) slow at sending Morse Code using paddles and can type much faster so I'd rather type than send PSK31/RTTY with paddles. Plus, using computer software instead of paddles allows you to take advantage of "macros" (pre-written text) and logging capabilities of the software.
      If you're trying to decide if you want a KX2, it's a FANTASTIC little radio!!!!!!! -Cliff

    • @QRPSchool
      @QRPSchool  6 років тому +1

      Some (but very few) CW-Only radios allow you to switch the receiver between CW, Upper Sideband, and Lower Sideband. The user manual will tell you if they do. The two CW-only radios that I have owned that do this are the Elecraft KX1 and the Youkits HB1B-Mk III. If anyone else reading this knows of others, please reply to this comment. Thanks - Cliff

      I haven't. I think it's an interesting little radio but there are two things that bother me about it...
      1. Fixed 1KHz Sidetone Pitch. This is too high-pitched for my taste. I actually am not aware of any other radio whose sidetone pitch is so high.
      2. Can't Handle > 30 Second Transmit Time. The manual says you can damage the radio by transmitting full-power for more than 30 seconds. That makes it less attractive for people like me who would also like to use it for digital modes.

    I just don't understand why there are not many little QRP radios designed for digital only in mind. There are 4 radios in your table designed only for CW, why no more people do the same for radios for RTTY,PSK, etc? Im in the market right now shopping for a QRP radio for ONLY digital which is the only I like at this moment, something that I can hook to a Windows tablet and be in the air doing PSK,WinLink, etc without a bunch of cables or interfaces in between. I narrowed down to the KX2 which in my opinion is a total waste of resources for what I need and the Xiegu 5105 which has internal antenna tuner, like an antenna analyzer and IF output which the KX2 dont have, is just that Im not trill for Chinese radios. Anyways, if someone knows about QRP radios designed for Data that put at minimum 5 watts please let me know, maybe I just dont found them yet, but is frustrating why many developments for QRP radios for CW only and nothing for data. I had a Kx3 in the past and the radio is top notch, for if you like voice or CW. I like Elecraft but I think they screwed up in 2 very simple things in the KX2, not an IF output? really? is that hard? and the thing to have to open the case to recharge the battery, that is very silly and can;t believe they did that.

    • @QRPSchool
      @QRPSchool  5 років тому

      Radios for CW-only can have circuitry that is less sophisticated than radios for SSB. Since the Digital Modes all transmit modulated audio that is Upper Sideband, a radio used for Digital Modes must be capable of SSB. So, sadly, a cheap, small, CW-only radio cannot be used for Digital Modes.
      I think you meant to question why the KX2 doesn't have IQ outputs (not IF), right? I have heard rumors that there are IQ outputs on the circuit board of the KX2... as though it might be possible for someone to tap into that. Again, it's just a rumor. Elecraft would naturally want to keep some of the KX3's functionality from the KX2 so that KX2 sales wouldn't cannibalize KX3 sales. I suspect removing IQ outputs from the KX2 is part of that strategy (just as the KX2 doesn't have 160m or 6m bands).
      I agree that it would be best to not have to open the KX2 case to recharge the battery. On the other hand, it only takes about 5 seconds to loosen the 2 thumb screws and remove the battery. And accessing the battery compartment in this manner makes it easy for those who wish to carry more than one charged Elecraft battery. So, I can see both sides of it.
      Keep an eye out for Hans Summers QSX transceiver kit. This $150 radio kit will probably be the radio you're looking for in order to put together a low-cost multiband HF radio for digital! Read about it here: www.qrp-labs.com/qsx.html

      @@QRPSchool Hi Cliff, thanks for your reply. Regarding the battery, I know it is "easy" to remove it but lets remember that is a radio ment to portable/sota/trail operations. I personally dont feel confortable opening a radio and be able to see all internal components while I am outdoor. Outdoor and mostly during sota operations we have many elements like snow, water, etc and open a care of an expensive radio to have to pull a cable from his plug? mehh, nop, is way easier to just plug a charger to it. If I go with a KX2 which i doubt the first this I will do is to drill a hole and put a connector in the case. I will take a look of the radio in your link, thank you very much. So far the Xiegu 5105 still winning.

      I understand why you would say that and I wouldn't recommend that someone buy a CW-only radio as their ONLY radio. A small do-it-all radio like the excellent Elecraft KX2 will allow you to do CW, voice, and digital. That said, a small CW-only radio can be a lot of fun to take into the field when you want a very compact, dedicated radio for a CW outing. If you saw my last video (made in May of 2019!) I worked 8 stations that were 5,000+ miles away using only a tiny Mountain Topper CW-only radio. That made the accomplishment more fun for me... like catching a big fish using lightweight fishing tackle. To each his/her own. It's all good. - Cliff

      Elecraft makes fantastic QRP radios and I've got 5 of them (2 KX1's, a K1, a KX2, and a KX3). But, to be fair, there are other radios that might be considered "best" by someone with specific criteria. For example, someone hiking the AT might prefer the tiny MTR3B sold by LNR Precision - even though every Elecraft radio is superior to it.
      For Field Day last year, my ARES group used my Flex-6300 with a 30" monitor. That radio, turned down to 5 watts with a 30" panadapter, provides an incredible QRP base station. You have to see it in action to believe how awesome it is.
      I do agree with you that Elecraft makes "the best" traditional QRP radios. - Cliff
