Hi Steve, Our modem is much more robust than typical Ham data modems. If we get some interference the modem comes right back, you don't lose an over. HF data is tricky, you require high SNRs to overcome fades or interferers. DV is different (at least I treat it differently), the brain can error correct for occasional outages. Just like we do for SSB.
Key question here is - how would you test any changes?
