- Hi gang.
I have added Olivia modes to PocketDigi. PocketDigi is a multimode
terminal software for Pocket PCs. It is freely downloadable from
The software is discussed on hampocket group at yahoogroups. My
posting to this group follows.

This is a new version of PocketDigi. There are two new modems
implemented - Throb/ThrobX and Olivia/Contestia/RTTYM. Both of them
have not been optimized for best S/N yet, but seem to work well.
The Olivia modem has been adopted from the code by Pawel Jalocha, but
simplified. I have removed the receive input processor, which does
kind of channel equalization. I actually do not think that Olivia
decodes better than MFSK16, but Olivia is much more easier to tune. I
wonder whether anyone will ever use the Throb/ThrobX modems.
If the microphone input is overloaded, the waterfall line will be
marked by magenta stripes now. I did not know myself that my device
gets overloaded by the Warbler TRX until I added this feature. The
overload must have added considerable distortion to the signal. If you
experience it, add an external resistor divider to the microphone cable.
Please report the bugs, annoyances, whishes etc. If I do not know
about the bugs, I would not fix them. Thanks.
Excerpt from ChangeLog:
- Added OLIVIA/CONTESTIA/RTTYM modes. Initial implementation without
- The three new modes tested for compatibility against MULTIPSK 4.1.2
- Known issue of THROB: AFC does not work correctly
- Overload indication. Magenta stripes are drawn over the waterfall if
mic input is overdriven.
- Fixed <NULL> bug in RTTY
- Fixed CW TX speed setting problem.
- Fixed problem of hanging CW TX at slow speeds.
- RTTY filters changed from IIR to FIR, which are faster on a fixed
- Added THROB/THROBX modes
- Enabled reverse for MFSK16
- Premliminary port of Feld Hell. Only TX enabled, paper tabe control
is still missing for RX.
- Added setting of TX prefetch sound card buffers. If experiencing
rattling sound during TX, increasing number of prefetch buffers may help
- Adding error message boxes to report problems with sound card. It
shall clarify, whether some of the OEMs are lazy to support duplex

Thank you for making Olivia available on PocketDigi!
We have recently been successful with Pedestrian-Pedestrian QSOs
between Hong Kong and USA with CW. Now, I want to try some Pedestrian
Mobile operation with Olivia soon.
