![]() You can put in any convenient place AmpMonitor on monitor - and control operation of the amplifier remotely.īoard size is x 92mm. To monitoring the amplifier on the monitor of the computer, is developed program AmpMonitor. Two programs developed for the PC that allow you to test the entire complex. The function of additional verification increases the reliability of the entire complex of amplifier control. If any measured parameter SWR, current, temperature exceeds the predetermined value, the switch on the power MOSFET turns off the power supply voltage of the amplifier. This solution the use of separate microprocessors allowed providing the maximum performance protection of the amplifier. Own microprocessor with high performance controls the operation of this board. Additionally, the microprocessor can switch the two connectors for the antenna. ![]() Control circuit of the amplifier.įigure 1 shows the interaction between the parts of the complex. The control output of 7 bands.Ĭombined m, m and m. Connection with computer via RS The control output of 10 bands. The best results are when I use 1 and 2 of your 3 ideas.Attention, check your spam folder in E-mail after registration and ordering. You are right about adding a check but I think that needs to be in the Band Voltage Routine. I wonder if you have any hints or ideas that might be worth me exploring. I was wondering if the BCD pins on the 20X2 might be getting changed due to the polling signals that N1MM is squirting onto the CI-V bus…and if so, is there anything I could try to stop that hapenning? Reading your code is a little beyond me a this point, but I could replace the internals of a Top-Ten band antenna-relay selector unit, AND have a BCD coded output for an Amp like the Quadra very neat. Should be simple but the hardware may not as straightforward as the simulation suggests Hi. It will be a simple Antenna selector to replace 4 x toggle elements. And maybe with a little antenna switching on the side. Is it standard radio write or read commands? I drive my Quadra with a Yaesu FT BCD control is not there. Along with the other connections to allow TUNE mentioned. I used a 10K resistor to the regulated 5 volt line. I switched to using CIV data which is working fine but anyone building this should know if they have no other CIV devices connected you will need to add a pullup resistor on the CIV line as the output from Icom is open collector. When using the converter in analog band voltage mode it would crash after 5 to 10 minutes, only a power cycle would bring it back. Thank you for posting this, it really makes the Quadra easy to operate. ![]() This allows me to use the tune button on the front of the Quadra if desired which keys my Icom automatically. It looks to me like pins 1 and 7 are swapped on the schematic diagram for J4 - the Yeasu band data connector. For example Elecraft uses it in the K3 for 60 meters. When the radio is switched on The BCD code 0x0 is not defined, but is used by some manufacturers. All we now do is for each band give a lower and upper limit for each ADC value accounting for rig variance and if the ADC value falls within a range then the appropriate band is chosen and BCD pins set accordingly. You then simply read the voltage as a function of ADC, 4. The code is split into 2 sections based on whether the CI-V is connected. ![]() Download the code, schematics and PCB layout here. ![]()
