Using FT-847 as an oscillator for practice


Steven KC3DOW
 
Edited

Hello,

I will be learning Morse code and would like to use the FT-847 for practice as an oscillator before going live some day.
How do I use the radio as an oscillator without going over the air?

Thanks,
Steven/kc3dow.

Connect a 50 OHM dummy load and reduce power to min, bit of a waste, build and oscillator!

He needs to build an oscillator part of the self-training!

You can also use a 555 timer chip.

Hi Douglas,
I am not sure I understand about using a timer chip.
Is this something that needs to be added to the radio?
I get the impression that the FT-847 cannot be used for practice.
What if I directed the signal into a dummy load?

The 555 timer can be built? with small components? to build? an oscillator.?
Google? Morse code practice? oscillator? and 555 timer chip.
Good luck.

Yes you can use your rig.
You are correct in that you can use a dummy load.
Just be sure to connect it to the correct antenna port.
Be sure to turn the power all the way down.

Just to put my two pennies worth in!

? What key will you be using? Iambic, swipe or straight? If you going to use a DL then I like to use a 600hz side tone (menu 6) as it always felt nicer on the ear, just my preference. Find the monitor setting on the FT847 and use that to adjust your output volume (mine is at 25, side tone menu 8). Set the weight to something that resembles clear dashes and not long ones (maybe worth consulting the “fists” on that) but mines at 3.0 (menu 7). Adjust the delay..... that I would say is quite important. Longer the better for practice as you won’t be interested in QSK break in while practicing and I think 300ms is the longest the rig allows. When driving an transistorised amplifier I find the delay at 300ms still too short as I’m not really expecting break in and I’m not exactly fast so find the carrier dropping in and out in between sentences (menu 9 maximum 300ms). Im sure people will say the opposite and use 10ms as it doesn’t drive the PA as hard but at 5w into a DL I would rather not switch so often and I guess it’s driving my VL1000 and hearing the chattering relays..... sends a shiver down my spine..Naturally you have the speed on the front panel so adjust accordingly.

? Also don’t forget to use the monitor button on the front panel above RF/AF or you won’t hear your side tone and process/keyer button next to it or you won’t have control over the speed and automatic dots and dashes. I use an Iambic key (Kent) and the keyer button give me automatically generated dots and dashes..... lazy I know. Won’t make a difference on a straight key.

? ?These are my preferences and only a guide but you can adjust yours to suit.

Good luck and hope to catch you in my log soon.
