Re: [softrock40] Re: Softrock V9.0, Attiny85 V2.0 and HF BPF Problem
- Hi Bob & group,
Thanks bob for the explanation, only a small remarks.
>> If it is set up using the screens within Winrad to enable the AutoBand Pass Filter (ABPF) option
The ABPF option is by default enabled in the firmware with filter points
4, 8 & 16MHz, so V9 users can run the firmware with no change.
Users of the RXTX v6 will need to disable the ABPF to use the I/O lines
for the TX and CW key lines.

lines, smooth tune and ABPF (eg. using the 9V1AL motherboard for both
Rx and Tx BPF switching) etc. can consider using the UBW instead of
the ATTINY based USB-I2C controller. The UBW has more i/o lines.
Information and .hex file of the firmware for the UBW can be found in
Using the UBW with the UBW Emulator firmware, it emulates the
functions of the ATTINY controller with Fred's v15.8 firmware - thus
ABPF, smooth tune, calibration once in firmware, setting of cross over
points for the ABPF etc. can be done from the PC, as if the USB-I2C
Interface with Fred's firmware were there.
- Hi, Don! A colleague of mine's got the same problem with ATtiny85 and ABPF you wrote about. So as far as I understood he has to remove v.1.12.20, to istall v.1.12.1 following the instructions in the files section, G0BBL folder. If I'm not right, please correct me, because I'm the only one who can help him.
Thanks in advance,

- Hi there,
Not sure where this thread started, but the v2.0 firmware does NOT have the ABPF function, that is unique to the versions of the firmware written by Fred PE0FKO, v15.xx.
The only support for BPF switching using v2.0 firmware and PSDR is with a modified version of the SDR1kUSB.dll file, although I am not sure whether that actually works with PSDR-IQ v1.12.20 or not.
Even if it did work, the combination of v2.0 firmware and PSDR-IQ is not very good, as it suffers from tuning glitches at every step as there is no Si570 'smooth tuning' function.
It is far better to upgrade to one of Fred PE0FKO's versions of the firmware (v15.12), both for the ABPF filter control, and smooth tuning, implemented within the AVR firmware.
