Remoting the LA-1K - Easy

Paul All Messages By This Member #103 Hi folks -? I've been running the LA-1K (love it)? totally remote for few months with the help of TRX-Manager author Laurent F5DEX.? Laurent worked with the Palstar folks to emulate the touch screen in every way using the TRX-Manager and I tested it on my LA-1K.? I have an ICOM 756 Pro III and have been operating it mostly on 6 meter FT8 and meteor scatter from Denver.? I also operate on the low bands with a modest antenna. I attached a screen shot.? Let me know if you have any questions. 73 Paul? NO0T -- Paul Sobon 1700 Bassett Street, Unit 1904 Denver, CO 80202 720-851-5959 LA-1K screen shot.PNG
Paul All Messages By This Member #104 By the way you will need to upgrade the LA-1K firmware to 1.03H for it to work with TRX-Manager.? Then all you need is a free RS-232 port on your computer and a straight (not null) RS-232 cable and the free trial TRX-Manager software.?? 73 Paul NO0T
N1UB All Messages By This Member #105 do you have a way to remotely power the amp on and off, or do you just leave it on all the time ? Doesn't look like the software has that capability. 73
Neil Foster #106 开云体育 That amp has a toggle switch for on/off. It is not "software" driven. I have the amp on only when I am in the shack operating. Neil??

Paul All Messages By This Member #108 Hi folks I don't like to leave the LA-1K running all the time so I built a remote power switch.? I bought one of the gray outdoor electrical utility boxes from home depot and some power cord and 240 male and female plugs.? Also a cord for 120 volt.? Then a Dayton 120 volt relay like this:?.? I use a smart switch that I plug in the wall to control the relay remotely and I put this circuit between the 240 wall plug and LA-1K.? ?I leave the LA-1K panel switch in the on position all the time. Here is the smart plug I use. I have two of them and switch them from my phone.? One plug for the computer, one for the rotor and one to put power to the LA-1K. 73 Paul Sobon, NO0T 1700 Bassett Street, #1904 Denver, CO 80202 toggle quoted message Show quoted text On Dec 26, 2018 5:57 AM, "BJN644" <bartnewhouse@...> wrote: do you have a way to remotely power the amp on and off, or do you just leave it on all the time ?

Neil Foster #109 开云体育 Not if you understand my shack set up. I use 4 monitor screens and operate facing the screens. The LA-1K is behind me. If you check out my QRZ.com page you will see the older 3 monitor set up. I have not updated the pictures showing the FLEX and the FTdx5000.. 73 Neil??

N1UB All Messages By This Member #110 Thanks for the reply Paul, that all makes sense except for the relay. How do you switch 240v with a 120v relay, are you just switching 1 leg of 120v ?
Rich McCabe #111 开云体育 In this case the 120 volts is the relay voltage.? You could use that or something else. “double pole” I the important part. ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of BJN644 Sent: Wednesday, December 26, 2018 8:39 AM To: [email protected] Subject: Re: [la1k] Remoting the LA-1K - Easy ?

N1UB All Messages By This Member #112 I guess I should have read the description where it said 8 pin, 120v is for the coil. Thanks 73
Neil Foster #113 开云体育 ?Let me clarify my "remote" usage and sorry if I was not clear. TRX-Manager has support for the LA-1K monitor and shows a representation of the front panel of the amp. This allows me to monitor on the monitor several important (to me) items: Power Out, Temperature and Id. As I mentioned the bulk of my operating is facing the 4 monitors. Neil?? N4FN ?
Neil Foster #114 开云体育 My memory is tired this morning...As Paul Sobon pointed out it requires the "H" update to the amp.

Paul All Messages By This Member #115 The relay is a double pole so it switches both sides of the 240 at the same time. It has two connectors for the 120v and 4 connections (2 for each of the 240 lines).? The coil on the relay is activated by 120 volts from the smart switch.? Since I operate the whole station remotely I can activate and deactivate the smart switches easily from the cell phone.?

Paul All Messages By This Member #116 Also forgot to mention I use Splashtop as a streaming server on the shack computer and as clients on my Android phone and my portable laptop to operate on the road. 73 Paul NO0T Paul Sobon 1700 Bassett Street, #1904 Denver, CO 80202 toggle quoted message Show quoted text On Wed, Dec 26, 2018, 9:32 AM Paul via Groups.Io <sobonpaul=[email protected] wrote: The relay is a double pole so it switches both sides of the 240 at the same time.
