FT225RD, FT902 repair

Old rigs of s.k. Eltje PA3CEE  here for check and repair The rig's looked like they have been working in a brown cafe for years He was a real smoker ... the "tank"  FT902DM  very heavy rig permeability tuning  very well build equipment. Plug-in modules.  The standard twin 6146 PA seen in most most older transceivers until 30 years or so ago shown under power with filaments on. Dangerous  be aware !  950V  and 350V are also present at the ACC  backside socket for external use  In the age of SSPA used to low voltages where  touching a working circuit is safe. Working with high voltages is extra dangerous nowadays. The socket board of the PA the brown C looks high-quality is a known issue of the FT902. This 100pf /1kV is to separate 350V  12BY7 driver ANODE  from the delicate  6146 grids -100 150 !  practical a wire direct from the driver anode is leadingto this C1   If shor...

N1MM Spectrum display with Hackrf1

N1MM does offer a Spectrum Display  that can display a panoramic view some  newer radio's support band data from the first broad m.f.  like the IC7300 Radios that connect to the PC using USB or WAN can offer a data stream to N1MM Spectrum Display so older types need an other solution. My K3 is connected with rs232 for CAT for low speed serial data  like frequency mode T/R CW keying  The Hackrf1 i recently got can be used  if your K3  has the Xverter I/O option. Hrf1 should already be working okay with SDR-console or SDR# before trying to connect with N1MM Spectrum Display Download ExtIO_HackRF.DLL  https://github.com/jocover/ExtIO_HackRF/releases This ExtIO_HackRF.dll   must be copied to the N1MM  program directory.    C:\Program Files (x86)\N1MM Logger+ Connect the  Hackrf1 with the IF out. Hrf1 USB should be pluged in , no other  SDR program must be running with it. Start N1MM like used to  t...

Hackrf 1

Now we are locked up in our houses as in a horror S.F. film The streets and sky are empty Just few weeks ago we where at our contest location PI4GN  IARU UHF contest at 23cm already the Airplane scatter was affected. We did not know that this would be our last contest . Saw Youtube Bill Gates warning. In 2015 he almost exact! pointed out what will happen when a Virus like Corona would spread out over the world.  "We" did not act to this serious warnings . Health authority's like in Taiwan Germany  did act direct in December and January last year so now when i see our "taskforce" i can't help thinking of that. Bill Gates said it all  I think of my child wood far travelling was only for few people. Our school organised a 50km day bus trip. The Greta generation is flying to Bali after having a well deserved ski holiday. Everywhere leaving a trail of plastic bottles and cans. The whole CO2 /energy transfer discussion is gone I hope the climate ch...
