Re: [Elecraft] K3S with Remoterig RRC1258

Should be no difference between K3 or K3S. The later model K3/0 minis have "K3S" on the front panel. See http://www.remoterig.com/downloads/RemoteRig_RRC1258-MkII_Users_manual-A40.pdf p 213 for setup for "Twin K3". 73 John N5CQ -Original Message- From:

Re: [Elecraft] K3 working on motorboats - possible

The shrimp boats often used a 108" stainless steel CB whip on a spring, and a large copper plate on the outside of the hull under water. They got out very well on 11M. With modern rigs and built in tuners, you could probably do well on 10, 12, 15 and 17 M too. 73 John N5CQ -Original

Re: [Elecraft] OT James Clerk Maxwell

I heartily recommend this book, the best I have seen on Heaviside https://www.amazon.com/Maxwellians-Cornell-History-Science/dp/0801482348 He had a tough childhood and became a telegrapher and virtually self-taught physicist who laid the foundations for modern electrical engineering. 73 John

Re: [Elecraft] Antenna comment

John, NT5C (now SK) was a very smart guy, and well educated in both geology and electromagnetics. He searched for his QTH via deed and terrain records, and the first screen was "must drain into 2 or more watersheds". He found a killer spot with gently sloping foreground in almost all

Re: [Elecraft] KPA-1500 failing on 160...AGAIN!

If it also happens with a dummy load, and the antenna analyzers shows the same graph as before for R, X, then it is likely one of the connectors between the KPA1500 output and the antenna. The one such problem I had was old jumper I had put in to add an SWR bridge/monitor. It looked okay, and

Re: [Elecraft] KPA1500 Power Supply Fan Noise

Eric, My KPA1500 RF deck is mounted on a high shelf, and the power supply is on low shelf below the desk. I have the fan speed on the RF deck set to 2 as a minimum. I almost never notice the PS fans, when I hear noise it is the RF deck. During the ARRL DX CW the fans reached 4 and it was

[Elecraft] Sold my K3 transceiver, so now selling the K3/0 and K3 Twin Remote Rig units I was using for remote:

(1) K3/0 mini SN 0158 (with "K3" on front plate), Remote RIg RRC MK2s v7 K3 twin radio and control units, Elecraft cables for K3/0 and for K3 connections, wall wart, power and serial Y cables. Original owner, great condition, working fine when I sold the K3. New cost $1200, will sell for $650

Re: [Elecraft] KPA1500 remote connection not working.

Burl, I have not been able to make it work either. At the remote transmitter site, I can connect to the KPA1500 via USB or the local LAN via TCP/IP. But in order to connect to the amp remotely, I have to use Windows Remote Desktop connection to the PC at the remote site. That works, but I

Re: [Elecraft] coaxial-cable patent# 1407 on 6apr1880.

Heaviside only applied for one patent, but it was a big one. He never collected any royalties on it, and all of his other inventions were published without patent protection, as he thought it his duty share his knowledge. He started out as a telegrapher, and began developed his math skills by

Re: [Elecraft] KPA1500 - Static IPv4 address

I set the IP by using the facility in my router to assign a fixed IP to a MAC address. Using the "KPA1500 remote" software I can access the amp on the local LAN via Ethernet or via the USB connection. I have not been able to access it remotely via the Ethernet interface by forwarding an

Re: [Elecraft] kpa1500

Courtney, The 12V RCA plug on the rear of the K3 accomplishes this just fine with the KPA1500, so I think you should be able to do the same thing. Current demand is very small. I am not using it to power anything else. 73 John N5CQ -Original Message- From:

Re: [Elecraft] Remote with Satellite

There are some 'constellation' networks planned with lots of small sats in LEO that will have much lower latency, but availability dates and pricing TBD. 73 John N5CQ -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Dave Cole (NK7Z) Sent: Saturday, July 7, 2018

Re: [Elecraft] KPA1500 and KPA500 set up question

I think you mean the KPA500 is coming on with the K3 but the KPA1500 is not. You can run an RCA phono patch cable from the 12V out on the K3 to the REM jack on the KPA1500 and it will turn on when the K3 does. 73 John N5CQ -Original Message- From: elecraft-boun...@mailman.qth.net

Re: [Elecraft] Amateur Radio Parity Act

The HOA lobby is good - they got exactly the wording they wanted in this bill and they got the ARRL to support it. It is not a compromise - it gives the HOA complete discretion and control. My HOA defined reasonable as follows: "A telescoping mast, 30 feet tall when extended, painted sky blue,

Re: [Elecraft] K3 Remoterig K3/0 MIC connection

When the K3/0 is connected to the K3, the rP or Fp menu sets the condition of the K3, not the K3/0. When the K3/0 is not connected, the setting changes the K3/0. But I have had much better luck with connecting directly to the mic input om the RRC control, so try that if you can. 73 John N5CQ

Re: [Elecraft] Remote AC power switch?

Many of the IP remote power switches (I use DLI) also have a backup control available via a POTS telephone hardline, plus a ping function to do a reset. 73 John N5CQ -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Wednesday,

Re: [Elecraft] K3/0 control not working with DXLap or N1MM

Jeff, I can connect the the K3 at the remote transmit site or via local LAN - only difference is the "SIP CONTACT" address in "RADIO SETTINGS" on the RRC Control. I use DHCP for the control RRC when on the LAN. Can you connect to the RRC radio unit via a browser interface from either the remote

Re: [Elecraft] Remote Rig logging

Mike, I use both LOGic9 and N1MM+ successfully via the USB connection to the K3/0 mini, using USB at the PC end. Have used it with both K3 and K3S at the remote site, and K3/0 and K3/0 mini at the control site. Make sure you have the latest firmware in the RRC at the control end. When you

Re: [Elecraft] Sloping Terrain vs Feedline Losses

The elevated radials should help reduce near field I2R losses, but the sloping terrain will help far field reinforcement and produce 'gain' in some directions, although at 80M it should slope for further than a mile away to really make a difference. I do not think elevated radials will change

[Elecraft] Minimum bandwidth?

At my remote transmitter site, I have 10 mbps 'down' and 1.2 mbps 'up' and everything works fine. I expect that 1.2 mbps both directions would work, but have not actually tried on a connection like that. 73 John N5CQ -Original Message- From: Elecraft

Re: [Elecraft] Remote Rig settings

Can you use a browser to look at the radio RRC at the transmitter site? Look at the status information before and after connecting and that may suggest a cure. The radio status will show OFF even when you are connected with the K3/0, at least it does on my setup. See especially in radio settings

Re: [Elecraft] Too many tuning knobs

The most amazing thing to me about the 15M CW pileup is there were dozens of stations calling when K1N was transmitting. Either they are not hearing him (but then why call?) or they just keep hitting the function key and hope to win the lottery!. This is over and above the usual group that calls

[Elecraft] Learning Curve of K3

Pet Peeve Alert: A steep Learning curve is a good thing! A steep learning curve means that you acquire each 'unit' of knowledge (the rise) in a short time (the run), which is good (rise/run = a large number means you are gaining lots knowledge in a short time). A shallow learning curve means that

Re: [Elecraft] K3/0-Mini Remote makes me wonder....
