K3/0-Mini - Experiences?
Locked
 
|
I'm in the midst of a terrible urge to spend some $$'s and the K3/0'-Mini's siren call is hard to resist. I've done a bit of reading on the RemoteRig products and there is scare info on the K3/0 mini.
I'd love to hear any testimonials, rig setups, real-world latency commentary, or even how you manage the firmware. Anyone play with the codecs? Thoughts on the different audio quality? My current though is using the K3/0-Mini on the same local network and I do some occasional work travel, might be nice to take it with me. Comments encouraged!!! 73 de K8OI

Hi!
I have used the K3 mini extensively over the year. Both over a ADSL line and 4G. . Latency is dependent on the internet access - on ADLS it is 10 ms on 4G 30-40 ms.The K3 mini is so well established and works so well with the K3 and the RRC 1258 units so it is just for you to go and buy it. There is no big difference with different codecs. I use the next lowest quality level and when running dual mode it consumes about 400 kbps. Going for better audio quality I could not hear the difference to be honest. I have worked over 700 QSO:s over a year and all major Dx-peditions on almost all bands which proves the quality of the system. My system can be seen on qrz.com. I control ACOM2000A:s and OM 2500A:s with rotor controls from Green Heron. Works UFB. Join the satisfied Electraft K3 remote club. You wont be disappointed. |

I used mine to remote my radio all of about two feet. It was nice having
a smaller control head on my computer desk. I bought it thinking I could use it to work Kansas while I was on vacation in Japan - and then I never used it for that. Kansas is the only state I don't have on CW. I have to get it set up again and get it working through my firewall. It was definitely a fun thing to play with.

I've been using the Remote Rig interfaces with my K3 for several years and the K3/Mini for the past 6 months or so. I'm a big fan of the Remote Rig devices, not a fan of the K3/Mini.
I started out doing remote operating with the K4VV group using an all software approach and the Remote Rig devices are an enormous improvement - reduction in latency, better audio quality, the ability to essentially just have a very long mic/key/headset cords vs. doing remote PC control. You still need a decent Internet connection. The Remote Rig interfaces will *not* correct for packet loss or high jitter (variable latency) Internet connections. If your round trip delay is much over 150ms, or varies widely from ping to ping, or if you lose packets, CW in particular will not be usable. The Remote Rigs also have a gazillion parameters and the manuals don't quite get you there - almost everyone has to resort to the "million monkeys randomly hitting keys" approach to get everything going. The forums on the Remote Rig site are very helpful and W1UE in particular has posted a lot of good K3 guidance. The K3/Mini has been a big disappointment, especially at the price - I should have just gotten a bare bones K3. The major problem has been the audio on both TX and RX when connecting the headset to the Mini (vs. connecting to the RemoteRig). On TX, I get loud hum and on RX, the audio is 20db down compared to the audio coming out of the RemoteRig. I sent the Mini back, Elecraft sent it back saying it worked fine. (They didn't even contact me, which I objected to and they are fixing that problem in their process.) On RX, apparently that audio loss is due to a filter that was put in to deal with digital noise getting in the audio, but running the AF gain at 90% on the Mini is not acceptable to me - distortion up and no head room for low signals or turning off AGC, etc. So, I have to connect the headset to the RemoteRig, then audio is fine - but the cabling is less convenient and messy. Part of the reason I justified spending the $700 was to be able to essentially use the Mini just like I would a "real" K3, but I can't do that. I may bring along the Mini and Remote Rig set up on travel some day if I keep the Mini - that portability is about the only reason to keep it. Others have had the same audio issues, others just naturally connect their headset to the RemoteRig, others have had no problems with the Mini - your mileage may vary. 73 John K3TN |

I have used the RemoteRig with a K3/0 (not the mini) to a K3/KPA500 combination and a SteppIR vertical. It works fine, but the RX audio is certainly not a strong as directly through the RemoteRig.
As others have noted this not quite plug and play and some tweaking of the parameters is required. There is a lot of good information on the RemoteRig forum and DJ0QN has some excellent network guides for those who have a limited understanding of this area (like me). Internet connectivity is key. You need solid connections at both ends otherwise latency is an issue. All in all though the system is seamless and is a game changer for remote operation.

I've been using the K3/0 mini for about a year for casual DXing and for
many contests. The K3/0 mini is perfect -- a mirror of your K3. Once you get used to the the fact that you are setting menus on the Remote radio, all will be good. The mix that is important is how you use the K3/0 to interconnect it to the remote shack. As stated here, many users are using the MicroBit RemoteRig product. This adds about $750+/- to your remote cost, but provides a far superior result than any other method. The killers in remote operation are latency and jitter (jitter being the varying difference in latency over time.) The Microbit boxes use dedicated hardware, and a very flexible software configuration. to allow you to tailor the box to your needs. The RemoteRig components are not designed specifically for the K3; therefore, they have a generic interface design, and Elecraft sells the specific interconnect cable for the K3/0. The majority of my contesting experience has been on CW in the Majors: CQWW and ARRL DX, running remote to K2LE/1 from my QTH in NH. The shack has 1.5Mb/.5Mb DSL service. The average latency on the connection varies from 120-150mS, with very manageable jitter. We run the RemoteRig boxes with 8kHz bandwidth, and this works very well. I don't feel handicapped by being remote at all... In many QSOs, I get unsolicited comments of great audio on SSB, and no issues with CW. It is just like being there. The Microbit boxes do have a lot of configuration parameters. You also have to know how to port forward from your router in the shack (unless you are using the box in your own home, and both ends are on the same LAN). If you are not familiar with networking, configuring the boxes can be a challenge. As the others have stated, the forum on the RemoteRig site is a good resource --> search it with Google first, as much of your frustration has already been experienced by others. Their is another solution with the K3/0 which is essentially 15-minute plug and play. It is a free solution, once you own the K3/0. This is the software and website of Brandon, KG6YPI -- an Elecraft employee and the guy you usually talk to if you are experiencing problems with the Microbit gear and K3/0. Your K3/0 has a USB connector on it. This connector can be plugged into a PC, and two codecs (send/receive) and two RS-232 connections (Rig Control and passthrough) are automatically installed. Brandon's site is www.remotehams.com. Their is PC software for the remote end as well as the server end. You can use Brandon's software without the K3/0 -- but it has some very cool features: - If you have a K3/0 and a K3 at the station, you get full control of the radio with all features. - If you want to connect to a remote on RemoteHams, where the remote is NOT a K3, you can still use the K3/0 for frequency control and other features. I use RemoteHams to control Dom, 3Z9DX's station, and run SSB from Poland. It works very well, though the overall latency is much higher. CW still has some work to be done. But I know Brandon is getting there. I've asked Dom if I could try his station in some contest on CW -- it will be interesting to see how that works out. I use both RemoteHams and the Microbit RemoteRig solution with the K3/0, and am very happy with both; I will continue to use RemoteRig in serious contest situations. 73, Gerry W1VE Hancock, NH Gerry Hull, W1VE | Hancock, NH USA | +1-603-499-7373 AKA: VE1RM | VY2CDX | VO1CDX | 6Y6C | 8P9RM <http://www.yccc.org> <http://www.yccc.org/> <http://www.facebook.com/gerryhull> <https://plus.google.com/+GerryHull/posts> <http://www.twitter.com/w1ve> On Tue, May 26, 2015 at 8:39 AM, jlbates4 <[hidden email]> wrote: > I'm in the midst of a terrible urge to spend some $$'s and the K3/0'-Mini's > siren call is hard to resist.

Hi John, I know nothing about these products other than a vague one paragraph functional description, but I do suspect an issue with the audio interface and/or how the units are powered and bonded.

Good perception, Jim... experience pays off. We had this same problem
with Andy, K2LE. We have two remoterig remote ends connected to the same common remote station. My audio has been flawless. Andy kept having poor audio -- muffled, microphonic sounds but no clear audio. It turned out to be the power supply, which was an underpowered switching supply. The RemoteRig box does not come with a supply. I power mine off of a 4A switcher, and it's fine. A 1A supply should work, but they seem to have issues. 73, Gerry W1VE On Wed, May 27, 2015 at 1:45 PM, Jim Brown <[hidden email]> wrote: > On Wed,5/27/2015 3:04 AM, John K3TN via Elecraft wrote: > >> Others have had the same audio issues, others just naturally connect their >> headset to the RemoteRig, others have had no problems with the Mini - your >> mileage may vary. >> > > Hi John, > > I know nothing about these products other than a vague one paragraph > functional description, but I do suspect an issue with the audio interface > and/or how the units are powered and bonded.

It all depends on what you want to achieve.
There are many different reasons for hams to want to operate RC. Different requirements probably call for different solutions. If you want to operate your home rig (or for that matter a real remote rig) when you are not at home, eg. when travelling, it might be both expensive and unpractical using the K3/0-Mini and RemoteRig set. Expensive or not depends on your financial situation of course. But you will spend something like 1270 USD and you will have to carry around some boxes and cables etc. But you have the luxury of having a very attractive man/machine interface! Still for the traveller: If you want an inexpensive solution, if you can accept to operate your rig from a computer screen and *if* you anyway carry a laptop ot iPad (or even iPhone) and you already have a PC in your shack (you can do away with a cheap notebook) you can limit your investment to less than 100 USD and still operate your K3+KPA+Kat500 quite satisfactorily. I dare to say so because I have done it for many years (>20k QSOs over 10 years, all CW). You will need to dig into some details about setting up networks and handle computers, so if you dont like to do this, it might not be your solution. I would not say it is free of problems/challenges, but I started from scratch, and am very satisfied with how it works. But if on the other hand you want to set up a stationary operating pos. for a remote station, it is a completely different ball game and I think the K3/0-Mini and RemoteRig set is by far the best solution for that situation. So my advice to you is to first of all find out what kind of use you are looking for and then select a solution. 73 de Paul OZ4UN Sent from my iPad > On 26 May 2015, at 14:40, jlbates4 <[hidden email]> wrote: > > I'm in the midst of a terrible urge to spend some $$'s and the K3/0'-Mini's > siren call is hard to resist.

I use one of three different solutions: 1. From a laptop I use two Winkeyers connected over IP via K1EL WKremote Server/Client programs. Keying may be either using a paddle or using the laptop keyboard. Alternatively it is possible to use only one Winkeyer at the remote rig and input by keyboard via Teamviewer. Audio is based on IP-Sound which is excellent for CW ( superior to Skype). 2. From an iPad or iPhone I use an app called K3iNetwork made by Mike KS7D. Keying using the keypad. You can even use voice input to the iPhone/iPad (and key your rig) using SIRI, but this is not yet useful and needs some more work on the app. But it could be developed to be an interesting mode for RC operation from a moving car. Audio based on Skype. 3. From an iPad or iPhone I use an app called K3iDitDah also made by Mike. Keying is done using the touch screen in a way like touch-type paddling. Although this app can be used as it is now it still does need some development work. Audio based on Skype. NB: It is possible to switch between solution 1 and 2 (or 3) on the fly while receiving! 73 de Paul OZ4UN Sent from my iPad On 29 May 2015, at 22:01, Joe Moffatt <[hidden email]<mailto:[hidden email]>> wrote: What remote solution do you use for CW?

Does anyone have K3/0 they want to part with? I'm stuck in apartment, I've tried everything from wires to magnetic loops. My problem is not getting out, its AFCI breakers. Any rf out and they pop (including the apartments around me.)
So if anyone has one they want to part with, let me know Brian KA7KDX brians@fl240.com |

Hi,
Sorry, I don't have a K3/0, but your problem certainly caught my interest. I had never heard of AFCI breakers before, but a quick Google search got me quickly reeducated and my eyes glazed over. Wow, these RF prone devices have been mandatory since 1999! Another federal mandate to protect people against their own stupidity (not checking their power cords for fraying and other damage).

YahŠ it sucks. I knew when I moved to an apartment that staying on HF was
going to be a challenge, but I was not prepared for the breaker issue. I found that with my kx3 and a wonderwand wonder loop on my kitchen table, that with 10 watts I can do some jt65 and wspr on 20m without popping the breakers. But my success has been limited and not worthwhile. I¹ve been a remotehamradio user for almost a year now, but I don¹t have much interest in ssb or cw these days. Remotehamradio does have a beta test going on for ³logging² software such as ham radio deluxe. I¹ve tried jt65 over it, but haven¹t had consistent results and get disconnected or have HRD lock up. I¹ve been avoiding buying a K3/0 for some time, just because I didn¹t want to spend the money on a ³non radio² device. But if I¹m going to get back on jt65, I think its my best option.

I recall reading something in an ARRL publication or newsletter that at
least one manufacturer of AFCI breakers has addressed and corrected the problem of RF susceptibility. That company is Eaton. It is a bummer that consumers must suffer from products that do not have sufficient RF immunity. If all manufacturers would 'step up to the plate' and accept that we live in a world where RF is present, often in strong fields, we would not have a problem. Hams are not the only cause of RF problems - think of the problems encountered by those who reside near broadcast stations. RF fields are emitted by police, fire and other emergency service transmitters. IMHO, more manufacturers must be willing to design products that can withstand reasonable RF fields. Of course, most consumers do not understand that, and the ham "is to blame". There was a parallel back in the 1950s and 1960s with television interference when many TVs were designed with front ends and IF chains that would pick up RF on most any frequency, much to the consumer's dismay and blame placed on the ham, even if his transmissions were clean of harmonics. It just about drove operation on 15 meters off the air because many TV sets used a 21 MHz IF that was 'wide open' for interference. 73, Don W3FPR On 5/30/2015 4:13 PM, ab2tc wrote: > Hi, > > Sorry, I don't have a K3/0, but your problem certainly caught my interest.

Fortunately these devices are not mandated in the UK.
Whilst the prevention of fires is laudable, ISTM that the regulators have jumped the gun and insisted on the use of a device that is still under development. Reading the WIKI on AFCI breakers, where lightning nuisance trips occur, they are under-developed "devices of the devil"! Perhaps it's time that litigation took place, along the lines of: "It was late at night and there was an electrical storm which caused an AFCI to trip, which resulted in the lights failing. My aging mother fell down the stairs in the dark and broke her collar bone, for which I hold you fully responsible"!!! It would seem that it is still not possible to fix 'stupid'! 73, Alan.

I hope to not live in an apartment that long :)

Hi, Jim - I'm a big fan of your guidance on bonding/shielding. There aren't a lot of variables to play with between the K3 Mini and the Remote Rig - I did all the usual things that have solved hum in the past, but didn't see any improvement. I'm going to run the Mini off of a battery, see if that solves the TX hum - but I mostly do CW, so haven't gotten back to it.
The RX audio problem is pure attenuation, I can crank up the gain on the RRC to overcome that attenuation in the Mini audio path but then I'm likely to be introducing distortion in the RRC. 73 John K3TN |
