My iso tee / RF sampler arrived today. Is this a good way to measure & set the attenuation? I put the sampler on my KC901J. Then put a 50 ohm load on the bnc sample side. Then fully 2 port calibrated

Did you call RT systems support ? Bob

Hi, Does anyone know of a good resource to find WIN XP drivers for RT Systems cables? Tried their web site, however all options for downloads are not available. Thanks, Chad WI9HF

Even in Flat audio mode, the TX side begins to hard rolloff at about 2600 hz. At 3000 you're down 3db and it drops quickly from there. No external filters are needed. It's flat from 20-2600. Andy WJ9J

I've discovered that the RKR1225 / Specta series radio RSS setting allows you to select "post" or "pre" limiting for the TX audio path for flat inputs on the accessory port. Not familiar with the

Yes, reduce the notch depth of the 144.61 c2037. ?If you do want to tx on the 144.39, then you will need at least 2 Q cans on the 144.39 equipment side and 3 Q cans on the 144.61 to notch out each

The flat IOs are for data use....to use the tx flat input for voice, it needs to be limited and filtered externally to prevent overshoot of deviation and bandwidth on squelch noise / noisy signals. I

The "FLAT/EIA" setting is a Radio Wide Configuration feature. Each channel has provisions for bandwidth and deviation, but nothing for De-emphasis/pre-emphasis. Jim

Here is some info from my notes: You have to set each channel to flat audio (I cannot confirm this at the moment) Make sure you set in accessories TX Flat to Pre limiter for best response. Good luck.

IIRC, there are a few boxes you have to correctly set the audio. I ran into the same issue first time I did an R1225. Andy (TARRA) via groups.io <tarra@...> wrote:
