This is the current state of our network. We're still trying to get the first few links in place.
The Diagram to the right represents where we are more or less currently. There is a link up between KF2HP and K7EK that operates at 1200 baud on 2 meters. We're working on getting another link up from K7EK to K4WDC via 70cm at hopefully 9600 baud also and then in the near future a link from either K4WDC or K7EK to N3XKD in south western Louisville.
Today these links are being made via NinoTNCs and re-purposed commercial radio gear Motorola and Kenwood sets. We have a stock of some Kenwood 70cm gear ~10-12 radios and other various bits and bobs. As we continue to grow the network we're willing to use gear that is in the common pool to help folks get onto the network.
The main hub at each QTH is comprised of a Raspberry Pi or other Single Board Computer to handle the TNC connection and the connection back into the shack via IP.
Hardware
Currently we're building out the network with NinoTNCs and Raspi's on the digital side as per the TARPN standards. We also have a stock of 440Mhz Kenwood radios to use for links. But we are not limiting ourselves to 440, if there is something that works better or is more appropriate, then we will use it. If there are situations where we have good line of sight, then there's no reason not to establish a link using a pair of ARDEN units as an example.
Bands and Frequencies for TARPN Usage
This list is based on what the recommendations that are listed in the SERA homepage
- 70 Centimeters should be preferred if a stable link can be made with it due to plentiful bandwidth and cheap existing gear.
2 Meters
- Note on 2 meters, This may be crowded with existing data, be cautious about utilizing frequencies that are commonly traditional packet. (145.030 145.050 145.070 145.090)
