RC 2000 - 0,1KHz step

[iw1rdz]

I'm using for some months the RC 2000 device, remotely controlling the Kenwood TS2000. I need help in configuring the RC2000 (and the TS2000) in the way to have a frequency step of the RC2000 rotary knob equal to 0,1KHz, that I like in SSB operations.
I am able to set 1KHz or 0,01KHz, but not 0,1KHz.

73, Steve.

up,

no one like me?

It is not possible to change :-(

very sad... I'll work on a homebrew panel with a big rotary knob and configurable steps... ;->

Hallo,

you can press the Main Dail on RC-2000 and swtich from Multi (1KHz) to Tun (0,1KHz).

In my RC2000 when I switch the vfo knob step changes from 1KHz to 0,01KHz and viceversa.

I am using homebrew board too:

tuningknop with 5 cm diameter and HEDS-5540 #A06, optical encoder, 500 CPR, 6,35mm axle (1/4") (look at E..ay.de) wired to the encoder inside the RC 2000 panel.
The encoder use 5 Volt DC from the RC 2000.

This evening I tested my new home-brew vfo rotary knob.

I keep the RC2000 connected and use the COM2 to connect an "Arduino uno" board with a level converter to comply to RS232.

I connected a 16x2 lcd display (useful now for debugging, don't know if in future I will keep it).

I used a DC motor as rotary knob, it is not precise, but it could be a good choice (at zero money...).
 
I programmed an analog input ADC to convert the voltage level that goes through motor (connected one side to 3,3v ref and the other side to arduino analog input).

If I turn the knob clockwise the voltage goes down and viceversa, so frequency has been programmed to go down and viceversa by 0,1khz steps.

Same problem here....

I bought a RC2000 mobile controller for my ts-2000 conected to the Remoterig and I found only one problem the dial step is always 0,001 in Fine Mode. It's a bit hard to get to 0,5 when you are in CW.
I like the way to tune on my ts-2000 but not on my rc-2000...

Is there any simple option to make it easy?

Thanks,

Hallo Willi,

Can you post some photos here how finally made it ?

Tnx

Hi Simon,

I send you some photos from my mechanical and electric solution with HEDS-5640

Hi, I modified an industrial encoder to work powered by 5V (I've just by-passed the 7805 internal circuit regulator) and connected to RC2000 according to Willi's suggestion.

I wanna say thanks to you Willi for your explanation; I tried a 20 pulses/rotation encoder and it is fine, perhaps it is too slow to work in fine mode, but surely better than the original RC2000 knob.

For those who look at my photos: attention that I used wires with different color compared to Willi's schema, but connections are obviously the same.

hi Willi,

Sorry for late response! lt looks great! Thanks for all details, it makes very fantastic, will need to make it one myself

Tnx again,

Hi there:

I want to modify my RC-2000 with an external encoder.

I've just ordered a 600 pulses/rotation two phases encoder. Can I use the same schematic as you?

I need some help.

Many Thanks

Hello Juan Carlos,

In the meantime I changed my Hedges Encoder to this one:
