After many years of owning a Yaesu FT-2000 a new transceiver arrived at my shack.
The Icom IC-7700 is big and weights approx 25 kilos.
Mine is in very good shape and i’m looking forward to make radio contacts on the hf bands with this new toy.

Acom 1000 Display replacement part 2
Within a week Val of Acom send me the ribbon cable.
I soldered the connector of the cable on the new display and also connect both anode and kathode wires to the little swtich board.
Now put everything back in reverse order (or you may clean the inside of the amp before close its cover)
Time to switch on some power and....
Looks great! Simple to replace a broken display on your Acom!

Acom 1000 display replacement. Part 1
Several years ago i bought my Acom 1000 from a local ham.
The only flaw was the display; some light bulbs failed but that was no show stopper for operate.
Because i planned to fix this issue i ordered a new display direct at the Icom factory.
These are no common displays also no common price!
A special bracket to hold the new type of display was also ordered as advised by Acom
For some reason the new display arrived directly on the shelf for some years....
But okay now in this Covid period i decided to fix the job.
First a safety warning : DUE TO HIGH VOLTAGES IN SUCH AN AMP, ASSURE THAT YOU WORK SAFE!!!
So convince yourself that the amplifier is safe to work on.
With a tin hobby knife remove the cover of the 3 knobs, do this very carefull.
Remove the knobs from the front pannel and remove the cover of the amp.
On top and bottom of the front pannel find the screws and take them out.
Gently pull the pannel from the case. Be aware of some connectors on the inside!
So now the first part is done. Remove the connectors from the frontpannel, note that 2 identical connectors exist so mark them before pulling them out.
Now unscrew the protection cover.
At this point you reached the display. The blue connector connects the display and the white the control knobs of the amplifier.
Unscrew both display and control board and pull both connectors gently!
At this point i had to stop; The display Acom sent me had not the ribbon cable and blue connector.
To desolder the connector from the old display is almost impossible without damage!
That was a mistake from Acom.
So i contact Acom and they send me a new ribbon cable with blue connector.
As soon as i got it i can continue this job.

Sommerkamp TS-780DX touched up!
Together with my radio friends Theo PA0KN and Edwin PA2LVD we saved a TS-780DX from scratch.
The Sommerkamp arrived from Belgium some weeks ago and had a few 🙃 flaws:
No audio on receive
No receive at all
No SSB transmit
Fault at 7 segment LED
Oscillating of PA after pressing ptt
Some knobs not original
Case scratched and damaged.
Enclosure was also repainted and original knobs where placed.
Very nice to have a working 40 year old Sommerkamp saved from scrap!
The result (and yes it works on 10 meter band)

ATU-100 (N7DDC) Antenna tuner kit
Bought a nice kit (ebay / Ali, etc) to build an automatic antenna tuner (design N7DDC) which can handle approx 100 watts.
Tuner is usable from 160 meter till 6 meter.
It has a small but very clear oled display that shows all information you need.
For 30 euro i had the smd presoldered version, so the only thing you need to do is wind the coils and solder some normal components on the board.
Complete kit, very well packed in a plastic box.
PCB with all smd components already soldered.
You have to wind the coils yourself
Tuner finished! Next step is a nice enclosure
