These are
"old" links that I moved here to "de-clutter" the main page. They are
in no particular order:
Decreasing
Intermod on the Kenwood TM-733A dual-band mobile transceiver
- This describes a modification that can greatly reduce the
susceptibility
of this (otherwise fine) mobile rig to intermodulation response due to
strong signals.
Substituting
the
SRF7043
in the
Yaesu FT-100 - Unfortunately, one of the more
trouble-prone components in the Yaesu FT-100 is also one of the most
expensive and difficult-to-get: The VHF/UHF Final Amplifier
transistor. This page provides some details of a usable (but not
perfect) replacement device.
Programming the Pictiva OLED Display - This has some very basic information on how to "talk" to the Pictiva (tm) OLED (Organic LED) display - but ONLY the now-obsolete Osram OS128064PK16MY0A01 - which is the 128x64 serial version. Please read the disclaimer at the top of the page before you do anything!
Narrow-bandwidth TV IF filter for the Icom R-7000 receiver - If you use an R-7000 receiver for analog TV DXing (or are intested in TV DXing in general) you might be interested in how narrower-bandwidth signals can help pull out weak TV signals. Note that this applies only to analog video transmissions and is not applicable to digital.
The Utah T1 Modem page - This has a brief description of a T1-rate modem that I built some years ago, long before wireless internet devices such as those that used "802.anything" were available. Circuit description, theory of operation, and schematics are available online. This page also tells you were you can't get kits for this modem...Want to send email? Go here.
