Re: [Elecraft] K3 won't unkey properly: Rear panel PTT
Don, If I'm not mistaking, all the signalink does is use a relay to ground out the PTT line voltage, much as a foot switch would do. A logic high on the PTT center pin would indicate a key up condition and should cause the rig to return to receive state. I could see where a flaky pull-up resistor could float the pin and cause erratic behavior. I yanked the PTT line, but the problem persisted. I would think it would go unconditionally to receive. If it went high, it did not cause the rig to go to receive. The good news is I'm beginning to see the possible cause of the problem, and it appears to be in the CAT rig control. When I finally get CAT disable, requiring a restart of FLDIGI, the problem seems to have mitigated. Funny how you can run a configuration for 2 years and never have a problem, until one day "poof"! Perhaps the issue is software related after all. 73, Dan On 7/13/14, 8:43 PM, "Don Wilhelm" wrote: > Dan, > > That sounds more like a Signalink problem than a K3 problem. > Please monitor the voltage on the PTT input from the Signalink to the K3. > > If the voltage when transmission is to stop is in the range of 3 volts, > that is the problem - that voltage is in the indeterminate range for the > typical logic levels. > OTOH, if the PTT voltage from the Signalink goes reliably to 5 volts, > then you have a K3 problem. > > 73, > Don W3FPR > > On 7/13/2014 10:01 PM, Dan Sherwood wrote: >> I have discovered an issue with my K3, (ser 5820). >> >> When using my Tigertronics Signalink USB device, the unit keys the rig fine, >> but when the interface unkeys, transmission ceases, but red XMIT light stays >> on and reception is muted.

Re: [Elecraft] K2 Control board resistance checks
Sorry Don, I'm new to the the Reflector, and didn't mean to create a problem. I figured since I was replying to a particular thread, it would all make sense. I guess I was wrong. So hopefully, here is some reference material. If I screw it up this time, just ignore everything, and I'll go away entirely. Dave Paul, Yes, those are OK. They are the DOT and DASH lines to the microprocessor and have nothing else but U6 on the Control Board to bring the resistance down. In general, a 10% deviation from the values listed in the manual are close enough. 73, Don W3FPR Paul Huff wrote: > Hi everybody, > > I recently started building a K2 and I've just finished the assembly of > the > control board.

Re: [Elecraft] K3 won't unkey properly: Rear panel PTT
Dan, That sounds more like a Signalink problem than a K3 problem. Please monitor the voltage on the PTT input from the Signalink to the K3. If the voltage when transmission is to stop is in the range of 3 volts, that is the problem - that voltage is in the indeterminate range for the typical logic levels. OTOH, if the PTT voltage from the Signalink goes reliably to 5 volts, then you have a K3 problem. 73, Don W3FPR On 7/13/2014 10:01 PM, Dan Sherwood wrote: I have discovered an issue with my K3, (ser 5820).

Re: [Elecraft] How reliable an internet connection is needed for A K3 remote to work well?
Run pingtest.net and make sure you have a grade A rating. You don't need much bandwidth as 1mbs in each direction is lots if you are the only user. However, latency issues will cause problems. As I understand it, the K3/remote uses a remoterig interface. The problem may not be your ISP, but the routers you are using at both ends can contribute to your issues just as simply. Btw, I have been running a remote base with a ts480 for about 8 years. I do run CW by hosting n1mm at the far end and using a winkeyer.

[Elecraft] How reliable an internet connection is needed for A K3 remote to work well?
A while back we tried Remoterig with a Kenwood radio and the CW generated was poor on the other end. This was presumably from dropped packets and or latency issues (Comcast on one end and a terrestrial microwave connection on the other end). Some dits/dahs were lost and others were prolonged, due to the lost stop signal. My understanding of the remoterig protocol for CW is it's not very robust, with no error correction or ACKing. We got around the CW problem by using a VNC and the CW is generated at the host end within the VNC window, using N1MM, directly keying the radio. If we were to use a K3 and K3/remote for the radio, would there be potential radio control issues due to the flaky internet connection, or is there redundancy and/or error correction built into the Elecraft remote protocol?

Re: [Elecraft] Premade tab welded battery packs
One of the Elecraft engineers mentioned that they worked hard to find a battery holder with low resistance contacts and conductors for the KX3. wunder K6WRU On Jul 13, 2014, at 5:47 AM, David Christ wrote: > Art sees the same thing I do.

Engineering runs the shop, and as long as there is enough profit to cover the costs and keep everybody reasonably happy (including Wayne and Eric), then they're perhaps the most successful Amateur Radio Transceiver company since, well, forever. I'll cite another example of a great company owned and managed by an engineer -- Dolby Labs. That fact made them extend development projects "for as long as it took," often for many years, far beyond the time most Harvard Business School types would have cancelled them. One of those projects was Dolby surround for cinema and home systems. About ten years ago, I heard Ray Dolby give an invited lecture to the AES, and his talk was about the history of the management of that company. It is a manifesto for technical companies being managed by people who understand the technologies involved, and the market for them. Eric and Wayne epitomize that philosophy! They probably won't die as rich as Ray Dolby did, but I'm sure they'll die equally happy! 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3] WRTC activity from K6KR
Good deal, Dick. I have the KX3 and that antenna (which I have yet to deploy). Only problem is that operating on the East Coast will spoil you for trying to work Europe with similar equipment from the West Coast. It's about the same as working Mass on 20 m from California! In 1997 I was driving on the Trans-Canada Highway in BC and Alberta. I was amazed how easy it was to work European stations on 20 m with my mobile set up and a Hamstick vs. doing the same from California. Enjoy your stay there, Dick! 73, Phil W7OX On 7/13/14, 10:07 AM, Dick Dievendorff wrote: I'm in a hotel in Westborough, MA.

Re: [Elecraft] KX3 "FAST-PLAY" field-test firmware now available (rev. 2.11)
Hello Wayne, I have tested this great feature on the weekend and it works really nice! Just a hint: When the CW decoder is enabled and fast play is switched on, the hint text on the VFO B display becomes mixed up with the currect CW decoder text. It would be nice if decoder text is suppressed until the hint text display is over. vy 73!

[Elecraft] Custom 700 Hz K3 Filters
The 700 Hz 8-pole INRAD K3 filters are back in stock. However, this batch is much smaller than usual, so it will probably sell out fairly soon; my guess is before the end of August. We made this batch so small because we are already planning ahead for the arrival of a subsequent batch around November 15th; just in time for the (winter solstice) holiday shopping season.

[Elecraft] OT: Bug Dot Stabilizer
Bug users on the list - I've confirmed a design that works on the old Japanese Skillman & the newer Hi Mound "coffin" style bugs with the flat pendulum & plastic top cover. I now make them to fit just about any bug out there as long as I can get the diameter of the round pendulum, thickness of the flat pendulum and at least a picture of the vibrating dot contact so I can determine the shape of the pre-tensioner hook. There has been a slight price change for ones made from brass. Aluminum ones are still $20 post paid domestic and $35 post paid to Canada and other international countries that accept U.S. International First Class postage. Customs charges (if any) are the responsibility of the international customer. Anyone interested, please email me off list and please don't comment on the list to keep off topic clutter to a minimum out of respect for the Elecraft users here.

Re: [Elecraft] Premade tab welded battery packs
Art sees the same thing I do. Take those 10 springs, uncoil them and fasten end to end. That surprisingly long, hight loss length of wire is what all the current has to pass through. Far from ideal for keeping the voltage and efficiency up. I have seen better designs incorporated into equipment but never in the secondary market.
