Re: low power out on HF

Kurt Sweeny
 

Has anyone found a good replacement for the stock fuse holders? I am thinking of replacing the stock holders but would like to avoid a weak/ ugly wire to wire splice.

Possible only if you connect your radio negative lead to the battery negative terminal, which is bad installation practice. Which I guess is one reason to keep the fuse, to protect people from themselves...

Not so fast! It is prudent to fuse both sides of the power cord. Just make sure the contact points are clean. Use a Dremel wire brush and then apply some DeOxit to retard future oxidation.

Usually only one fuse is sufficient, remove the ground wire fuse.

Do NOT, repeat, do NOT remove the ground leg fuse
in a mobile installation.  A lost vehicle ground can
cause attempting to start the vehicle to use your
expensive radio to become the ground path according
to many sources.  That is why the factory lead has
that fuse.

Very first thing: check the fuses in the DC supply cable for oxidation.  They are notorious for that and, when contaminated, cause a significant voltage drop that can manifest as a loss of TX power out.  This may or may not be your problem, but it is a simple check that could (if the culprit is found there) save you headaches and money.

How can i delete this and inter my call letters ?

Re: IC7000 with ACLog

 

Can you give details on connecting through Rigrunner? I thought RR was just power distribution. What cables do I need? I'm just interested un using ACLog, not transmitting CW.

When I was a maintenance manager I also used Tiger Direct to buy a lot of computer equipment. Good prices and good service back a few years ago.

Yes.

USB to CIV converter - many on ebay.  This will provide rig control and TR switching.  Setup your software PTT control via CAT.  < $25

13 pin DIN to 3.5 mm audio cable - available from Hamdaptor, again on ebay < $15

USB sound card (dongle) - available from many places, < $15

WSJTX software - download for free; get on groups.io WSJTX mail list, great place for support.

I use this setup with my ASUS windows 10 laptop.  It works very well.

I have about $50 invested in this setup.  You could do it cheaper if you try.  There are also many other approaches, many of which will work well.  Some are a lot more expensive.  Each approach has its tradeoffs.

You will have a learning curve to get everything coordinated, but that's the point. You will learn what to do!

I have no financial interest in anything I've mentioned here.

Good luck,

Oggetto: [ic7000] Share my driver board PCB file (KiCAD + Gerber)

 

I recently fixed an IC-7000 with seriously burned driver. Due to lack of the outdated parts from ICOM support, I created the PCB and uploaded the files to github and oshpark, hope this may help who want's to fix the module themselfs.

https://github.com/sgub/ic7k-driver-pcb
https://oshpark.com/shared_projects/nPS2hozq

I reduced the pin spacing from 1.5mm to 1.27mm, for better availability of parts and easier mating with the PA board, and added a footprint for the resistor to suppress self oscillation.

While I (thankfully) don't need this at the moment, I want to thank you for putting this on GitHub - essentially in the public domain.  Creating a PWB is big step for a lot of people and you've just saved some unknowable number of people that effort.
