@@rosscopeeco69 Yes and yes, two components are swapped out then two components removed Then an hf pcb with an SI4732 chip is installed. The firmware CEC_0.51hf is then installed...
hello my friend , i just had my uv-k5/8 from china, today, what do i need to do the mods ? i have the program cable as wel, do i need the egzumer for the software ? greetings from Bruges Belgium
@tennesseered586 drop me an email and i can send the schematic. PSU regulation , changed all the caps, all the resistors. re-aligned, re-wired the lamps and dimmer... g8ubj.io91uj@gmail.com
I haven't looked but its probably the same as the resistance. To be honest unless you already own a calibrated capacitance meter I would not attempt this. Peak offer a calibrated unit and assuming you buy one why would you then use the Owon?
@@Rex-G8UBJ Thank you, the problem is that it has stopped showing measurements, it only shows 0 and the calibration is totally different from the other measurements, it does not respond to the usual logic.
Oh wow, I had one of these back in the 80's, although I used it mainly on 2m AFSK at 50 baud. Lovely old machine, I even managed to get one of the private circuit control units to go with it, that had three 1000-type lever keys instead of the dial and pushbuttons used on telex. Sadly it all got destroyed in a house fire, and I never managed to get another one 😿
Sorry I have no information on that. I'm sure its just an approximate good / bad measurement. I would personally look up the diode spec and measure the forward voltage drop
Thanks for the Video.. Can you tell me what Version of Firmware you have running there and also which HF mod board is Installed in the radios.. Cheers Denis
I've noticed that even with a stable voltage source, the LSB bobbles +/- one or two counts meaning that OWon seems to be trying to provide more resolution then the meter is truly capable of providing. As a hobbyist the meter provides more resolution than I need but it would have been nice to know about the noisy LSB issue before I bought. Thanks for the instruction on calibration.
Short, but sweet. So nice to see how it used to be done with a Creed 444, or Siemens T100 in my case, a homebrew terminal unit and scope displaying a crisp lissajous figure. Sadly most of the RTTY videos on RU-vid I’ve viewed recently are put up by ‘aholes’ who know little and annoyingly keep referring to R T T Y as ritty! 👏👏👏
If you short the probes it should go to zero, its picking up the mains at 50Hz. You can do the same calibration set up procedure in frequency mode but its probably okay
That's normal, if you don't have the leads or connections grounded, then they will act as bad antennas, that will never-the-less pick up the ever-present "mains hum" frequency of your power grid that's pretty much everywhere in a house - 50Hz.
great video for two reasons: 1) did not know this unit had calibration options OR speed options; 2) your voltage reference. As to the latter: do you sell the boards/and or complete unit?
I'm meaning analog audio...Im connecting my amp to a vacuum tube and I want to have as much isolation as I can between them but still see the audio levels through it
No this is digital only. If you want analogue audio the other side you will need a PC sound card and drive it through the isolator. This solution is expressly for isolation when connecting a PC to a Ham transceiver over USB You can obtain high isolation 1:1 audio transformers which are a better option for removing ground loops and protecting equipment from RF or high voltages
I have the acom 04at and acom 1200s and I don't know what parameters to set for the coupler to work. And to put the 4 antennas in it. If you can tell me something
once it can see the tuner you can set up the antennas, assigning them to a port eg antenna port 4 10M Vertical etc.. then tune the antennas section by section
