Supporting the KC901V for bench operation

Whilst bench testing the KC901 I have noted a number of difficulties.

- The units light weight and size do not help its stability when a heavy cable is connected
- The display is not always at the ideal angle for you to view whilst using other equipment
- It can be dragged off the bench by cables or objects connected to it. (see below)




Two possible solutions are

1/ If you have the new Pelican design carry case, you can operate the unit whist it is sitting at an angle in the box and add stability by placing the cord placed over the lid.



2/ Build yourself a mount for the KC901V which has a wide base footprint, gives the instrument the right angle of operation for your purposes with weight added or with it fixed somehow to the bench to make it stable whilst it is being used, even when heavy leads are connected to it. My base was made from an old re-purposed 8 inch disc drive case that I had been previously using to store components. I had considered making a frame from metal clipped into the KC901V rear slots, but the plastic connections will not scratch the KC901 case and I can use the box to transport a suitable length of antenna cable and other accessories such as my circuit board log antennas when in the field, so it is useful as more than just a base. The angle I ended up with was the face tilted back 22 degrees from vertical which had the display and keyboard directly facing me at a comfortable arms length away.



I placed a reasonably heavy 150W attenuator behind the KC901V on the plastic base to add weight and improve stability.

The top edge of the KC901V is retained by two plastic taps slotting into the belt mount holes and the aluminium strip with a slight bend at the end captures the metal back edge of the case.

You can use whatever technique or approach you like to make a mount but the principle is establish the right angle and add weight for stability.

This shows the base mount side on and how the clip grabs and locks the metal top edge

    Lala land,
    OK, good observation and fair point. Ugly but functional works for me until I had something better.

    Post a picture of you wonderful workbench and you interesting testing with the KC901V and we will have something to talk about.

    cheers Noel

    Hi..i am a new user here. In my case i am using can unbalance and drag my KC901V off the work bench which is why I added ballast to my not so attractive home brew solution.

    Maximo,

    Actually they are second hand cables from upgraded transmitter sites, so yes they are high quality and used between VHF cavity filters and in equipment racks, but they not cost me much. Such cables are easily obtained at Australian "amateur radio white elephant sales".

    (I must admit I had to buy some really good quality low loss "armored" SMA cables to use on my 22GHz spectrum analyser)

    cheers Noel

    @VK3NH hahaha, that is because you use high high quality cables, "billionary cables".
    But for "poor man cables" works fine, hahaha.

    Maximo,

    Good to hear from you again.

    Yes the stand you suggested works very nicely.

    I still need to use my home brew case/stand because the heavy low loss cables tend to pull the unit over otherwise.

    cheers Noel

    @BG8NPK Nice to see my idea is now in your products accessories.

    Maximo,

    It certainly looks good. A much better angle for using the instrument on a bench.

    cheers Noel

    @BG8NPK For me works good. Cheap, light, folding.

    @EA1DDO

    this stander is exciting

    Maximo,

    Nice and compact stand. My issue was more the fact that the heavy low loss cables I am using can unbalance and drag my KC901V off the work bench which is why I added ballast to my not so attractive home brew solution. However for improving the working position of the unit in most circumstances this option looks good.

    regards Noel
