[Elecraft] K3 and Icom PW-1
Has anyone been successful in interfacing the K3 with the Icom PW-1 amplifier to allow for auto band switching of the amplifier? 73 Mike W9QO __ 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
Re: [Elecraft] K3 and Icom PW-1
microHAM microKEYER II, DigiKeyer II and/or Station Master provide isolated/regenerated CI-V control and PA PTT capable of controlling a PW-1 with a K3. DXLab Suite provides a software solution (the Secondary CAT Serial Port in CI-V Commander) to controlling the PW-1. I know of no other products currently on the market capable of translating serial controls in one format to the CI-V transceive necessary to control the PW-1. User Manuals for the microHAM products are available at www.microHAM-USA.com/downloads.html - general connection diagrams can be obtained by emailing a request to i...@microham-usa.com, and information on DXLab Suite is available at www.dxlabsuite.com 73, ...

Re: [Elecraft] K3 and Icom PW-1
Oh, there are a lot of them - the native CT17, Rigexperts, Rigblasters etc... None of the above will translate Elecraft CAT commands to Icom CI-V transceive protocol broadcasts to allow the PW-1 to track or change bands with the K3. Without the proper data, the PW-1 doesn't operate as an automatic amplifier - it must be switch manually from band to band. 73, ...

Re: [Elecraft] K3 and Icom PW-1
As Joe mentions, my personal experience using the Station Master is very good; it is a well supported and fully functional solution that also provides antenna switching and rotor control among other capabilities, and I just recently started using it remotely. 73 de Dave, W5SV On 3/22/12 2:33 PM, Joe Subich, W4TV wrote: microHAM microKEYER II, DigiKeyer II and/or Station Master provide isolated/regenerated CI-V control and PA PTT capable of controlling a PW-1 with a K3.

[Elecraft] K3 and ICOM PW-1
Check the circuit diagram. If they are using the same concept as in my ICOM IC-2KL, then the amp has absolutely no protection without ALC.

RE: [Elecraft] K3 and Icom PW-1
As I think about this I'm not sure that this will work for the PW-1. Because the PW-1 handles the WARC bands, I'm going to guess that it requires a CI-V line for band information rather than the band level output. Joe, do you know for sure? The way I sync my IC-7800 with a PW-1 makes it clear to me that it's a CI-V path, not a band voltage.

Because the PW-1 handles the WARC bands, I'm going to guess that it requires a CI-V line for band information rather than the band level output. Joe, do you know for sure? The PW-1 manual shows the +8.0 V reference and Band Voltage input connections on the ACC sockets consistent with the old style (2KL, 4KL, AT-500) band switching system. If the connections are present, I see no reason they should not be functional but I do not have a PW-1 to test with. 73, ...

RE: [Elecraft] K3 and Icom PW-1
Yup. Joe's StationMaster solution is better if all-band switching is important to you. I'm an occasional driver on the WARC bands and I can reach over to the PW-1 control head and move to 18 or 24 MHz manually. I really want the automatic switching for contest operations.

RE: [Elecraft] K3 and Icom PW-1
One correction ... I misread the MC14028 spec sheet. There is no none of the above output from the 14028. To include 6 meters, it will be necessary to add a separate decoder for BCD 10 ... not difficult but just one more step. 73, ...

ICOM did not provide for the others. Actually, my design uses a resistive divider network - with standard 2% resistors - that takes +12V (regulated for reliability) and provides the proper voltage for all bands 160 - 6 M based on which tap is grounded. It is a bit different than the Top Ten approach which uses individual trimmers to set the output voltage for each band and source drivers that have been discontinued. Note - Icom uses the same voltage for 17/15 and 12/10 so it requires 8 outputs to cover 160, 80, 40, 30, 20, 15/17, 12/10, and 6m. The decoder does not directly decode 6 meters (BCD 10) but the circuit can be configured to select 6 as a none of the above case (BCD 0) or a dedicated 6 M circuit could be added to the basic decoder. I have been asked off-line if I would be willing to offer and interface - either complete or as a mini-kit. I have no interest in building a complete product by hand and the cost of a small run in Europe is currently prohibitive. However, I'll ask here one time only ... how much interest would there be in a kit? Should a kit include a case or are users likely to incorporate it in another piece of equipment? Responses direct only ... 73, ...
