Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

I'd be careful what I asked for. Sma connectors are way more difficult to connect than TMP. In close quarters almost impossible to turn the nut on a sma and the fine thread has to be exactly aligned. I have two custom-made tools for doing that and that is not always good enough. Better

When I built my K3, my thumb was bleeding after inserting the TMP connectors. They are nasty little things! 73, George, K5KG. On 10/20/2015 9:35 AM, Alan Sewell N5NA wrote: You were right Guy. My rig ran fine all day yesterday and then last night I had the same problem. Opened it up and

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

I though that is what needle nose pliers and surgical forceps are used for.plugging in TMP connectors. The side tabs on the TMP connectors make for an excellent gripping tab for forceps. 73 Bob, K4TAX On 10/20/2015 8:41 AM, George K5KG via Elecraft wrote: When I built my K3, my thumb

Maybe the next version of radio can use SMA board mount connectors. Sent from my iPhone > On Oct 20, 2015, at 08:41, George K5KG via Elecraft > wrote: > > When I built my K3, my thumb was bleeding after inserting the TMP connectors. > They are nasty little things!

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

Vic has it correct. Thinking carefully about what I did, without ever hurting my fingers: I gradually insert the TMP lightly with a back and forth twisting motion and ALWAYS wiggle the connector a little until I feel the opening for the center conductor. Then a slight bit more push after I'm

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

The cost differential probably makes that impractical. However does anyone know if there is a tool for insertion and removal of those TMP connectors? I'd surely invest in one if I ever saw it. They definitely are a PITA. 73, Bob K2TK ex KN2TKR (1956) & K2TKR . On 10/20/2015 10:13 AM,

Hi, btw: The TMP cable 12" is the Elecraft part: #E850339. 73 - Petr, OK1RP - http://ok1rp.blogspot.com -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-No-Receive-No-Transmit-SOLVED-tp7609301p7609344.html Sent from the Elecraft mailing list archive at Nabble.com.

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

The TMP connectors are not that hard to insert, but the danger is that it is easy to apply too much force when they are not aligned properly, and damage the socket-board connection. You can lift the trace from the board if you are not careful (yes, I learned this the hard way). The trick is

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

Hi Bob, yes, sure. The TMP hand-crimp-tool link is here: http://www.scsiglobal.com/TaikoDenki/hand_crimp_tool.htm More details about the TMP technology (I do not like it :) is here: http://ok1rp.blogspot.ch/2015/10/elecraft-k3-tmp-k01x-a1-connector-and.html regards, 73 - Petr, OK1RP -

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

Alan, big congrats! Seems like Mr. Murphy left your house and you found it quickly. In general it looks like boards should be redesigned for more reliable connectors as SMA or even better one. 73 - Petr, OK1RP - http://ok1rp.blogspot.com -- View this message in context:

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

You were right Guy. My rig ran fine all day yesterday and then last night I had the same problem. Opened it up and used some needle-nose pliers on the TMP connectors to twist and push. I was able to insert a couple a little further and found one was only about half inserted. Maybe I have

Re: [Elecraft] K3 No Receive, No Transmit - SOLVED

The outer shell of the TMP plug can be connected without being fully inserted into the TMP connector. This can result in an intermittent on the center conductor that comes and goes with temperature change, or breathing hard, or changes in phases of the moon. The little flanges on the TMP plug
