8dtek Combo Jet TSM8800


I am looking for help: after trying different firmware for my meter, I ended up not having a backup of the original firmware. Now I am looking for a file like this:


If you have it, please contact me!

For general information: this meter is sold under different labels and know as

  • 8dtek Combo Jet TSM8800
  • SF610 Combo
  • DreamSky Combo
  • Openbox SF30
There are at least the following hardware/LCD combinations:
  • HW20 - LCD01
  • HW20 - LCD02
  • HW20 - LCD03
  • HW40 - LCD04
My meter uses HW20 with LCD01. Firmware files with LCD02 will not be usefull at all, but firmware files with HW20 - LCD03 can be used. However, the screen will look funny, as the firmware adresses the LCD in the wrong manner and an interlace effect happens.

This meter was tested by TELE-audiovision:

Thanks for any help finding the orginal firmware!

Sat-Kabel SPM22


I just received my latest meter: a SPM22 made by  Sat-Kabel. I got it at a fair price on eBay and it is working fine.

First thing I did, as usual, was to properly clean it, to make it look brand new - well, sort off, at least.

I thought you might find the inside interesting, so here are a few pictures.

First I disassembled the SPM22. This is easy to do, just unscrew 4 screws on the back and remove the front cover. Remember to first remove the rechargeable NiMH battery pack (5x AAA 1.2V cells).

Then you need to remove the metallic cover inside and remove the LCD screen. This gives access to further 4 screws. You can now remove the metallic case containing the PCB. It looks kind of empty...

..because all the logic is on the other side. To unveil it, remove the metallic cover. Interestingly this meter does not use regular tuners as most meters use. Instead Sat-Kabel seem to have developed their own tuning circuit, which by the way is driven by an ATMega32.

 Here is a close-up of the LCD display:

On the backside you can see the reference numbers (in case you need to buy a replacement screen):

My meter came with firmware 42.03 installed (I guess it is quite a new version, though the manufacture day on the PCB refers to 2007). On the PCB there is a prominent JTAG connector, but sadly I have never seen firmware files for the SPM22 available for download.

The meter itself is OK. First impression is not so good, as the meter is really basic. But after using it for a while, it is actually quite clever, as its small size makes it an omnipresent tool and for most quick jobs its functionality is really enough: to tune i.e. a DVB-T antenna it is easier to carry around a meter the size of a scientific calculator than a meter the size and weight of two bricks...

I think it is a good choice for technicians having to do repetitive installation tasks, without major fault fixing jobs.


My blog will be updated regularly again...

Hi there,

After a long time, I decided to update my blog again...

I stopped updating my blog when I started to collaborate with TELE-audiovision, formerly known as TELE-satellite. During almost 3 years I wrote reviews for professional equipments (meters, receivers, modulators, signal generators, etc.) and workshop articles.

Sadly, times move on and the demand for a printed magazine (even with free online PDF edition) stared to fade away and the publisher (who became a great friend of mine) decided to stop the publication of what probably was the best satellite TV related magazine.

The good news is that almost ALL EDITIONS EVER of the magazine will be soon available for free online view.

*** UPDATE ***

All magazines published are available for free!
