Re: Linearity eeprom setting
Hi, I am getting more confused now lol. I am talking about 0B and 0D *0B if the inductance line has a linear pitch 01 should be entered in the cell. The* *default value is 00.* And *0D if the

Re: Linearity eeprom setting
I think you misunderstood the manual. Linearity is a on/off switch. It disables a software formula that tries to overcome the lack of linearity of detection diodes. That should only be used if your

What about the IN34A diode used in the LDG AT100 ProII? This one has even lower junction capacitance. 1pF @ 1mhz

Linearity eeprom setting
There are 2 linearity settings for L and C. How do I interpret this? Linear is: 10pf, 20pf, 30pf, 40pf? Or 10pf, 20pf, 40pf, 80pf? How must I interpret this? 73 Bjorn de PD5DJ www.pd5dj.nl

Re: Max SWR
It depends upon your operating frequency and what type of load you're trying to tune. It's probably not the answer you're looking for. Al, K2ZN

Max SWR
Can anyone tell me what is the max VSWR that the AT100 (3.2 firmware) can generally tune? Thanks

Re: ATU-1000 SWR Bridge adjustment question
I have performed a "calibration" but I think it is harder then suggested. There are some factors playing in the ATU-1000 Situation. 1. When setting eeprom address 30 to 01, to activate highpower

Re: Programming & compiling from github source code
Kaz You must be using an early version of the firmware, the internal reference is set in version 3.2 with: ADCON1.B0 = 1;? ?// ADC with the internal reference ADCON1.B1 = 1;

Re: Programming & compiling from github source code
Hi, The ATU-100's power measurement issues have been resolved and are now tuned correctly. There was a problem on line 63 of pic_init.c. ADCON1 = 0xA0; This will supply the ADC reference

Re: Programming the PIC16F1938 with a MiniPro TL866-II Plus
It sounds like you've done your homework about the differences in the devices! There's an open source program to control the minipro boxes. You can probably add the changes you've discovered for the

Re: Programming the PIC16F1938 with a MiniPro TL866-II Plus
Yes, I was hoping that would be possible. Unfortunately it seems there is only a DLL file that contains all chips information. I've had a peek into it by disassembling it, and the infoIC2Plus.dll

Re: ATU-1000 SWR Bridge adjustment question
Get a wattmeter and dummy load. Feed power thru the tuner in the FWD direction and set the pot to give you the same power the wattmeter says it is. Now switch the in and out of the tuner and do
