[aprssig] Fwd: 220 band radio for Appalachian 9600 baud backbone? -SIG

[Brian Webster]

I believe TARPN is using Pi’s and one of two different HAT TNC’s. EastNet is all TNC2 clones with 6Pack firmware in the ERPOM and Flex as the node operating system.

 

Thank you,

Does that TARPN group or Eastnet group use dual port Kantronics 9612 TNCs in their networks?

The TARPN group has been testing various radios for packet links and their suitability. Tad Torborg is a good contact point with that group. I can give input from the NY and eastnet packet group.

This radio was suggested as an available 220 radio for this application:

 

BCM-220 1.25m Mobile Radio — BridgeCom Systems, Inc. <https://www.bridgecomsystems.com/collections/amateur-mobile-radios/products/bcm-220-1-25m-mobile-radio> 

 

Does anyone have one?  In use at 9600 baud? 

Do you have a KPC-9612 for testing?

Do you have quality attenuators for making weak signal tests using the 9600 port on the 9612?

Does the radio have a wideband access to the modulator and demodulator for such use?

Do you need a partner and/or another setup to make this test?

Do you know someone who does?  Or another packet radio user group you can ask?
