Quantar Local Link

Postby geekguy15 » Fri Nov 01, 2019 9:20 am

Good morning everyone! I have a theoretical (at this time) project I would like to get some incite on. Our ham radio club is looking at the prospect of getting into P25 after our dissatisfaction over the performance of certain unnamed ham equipment.

Our current setup has 2 analog repeaters linked (UHF-VHF) via an Arcom RC210
Ultimately would like to have the same setup but with P25 mixed mode repeaters but we were told that this can't be done using the RC210.
However we were told that we could have 2 P25 mixed mode repeater using the RC210 but we could not link the P25 side, only the analog.
What kinda of linking equipment would we need to link both repeaters together in mixed mode? The purpose of keeping mixed mode is to allow
members to slowly migrate to P25 gear.

I appreciate any info on the issue, thanks!

Linking two Quantars on the same site in P25 mode is no more than 5 minutes work if you have (or have procured) the necessary V.24 interfaces. These can be genuine Moto boards, the P25NX style, or my own single chip breadboard type. The details of the connection and settings are in the Quantar station manual under the description RT-RT mode.

If you program the repeater for mixed mode and make an analog connection as well between the machines then yes. To be clear the digital connection doesn't carry analog and vice verse. There is no codec function in the Quantar.
