From 2c815cec02bd21c1adb25dd6fb0c6640c6671016 Mon Sep 17 00:00:00 2001 From: yuancheng Date: Wed, 22 Jul 2026 00:07:16 +0800 Subject: [PATCH] Revert 150-160MHz as "valid" for POCSAG frequency - hardware rejects it Confirmed on real hardware: setting POCSAG frequency to 155MHz makes MMDVMHost exit immediately with "Received a NAK to the SET_FREQ command from the modem" - the MMDVM_HS_Dual_Hat's ADF7021 chips are tuned for UHF and can't physically retune to VHF 150-160. Since MMDVMHost controls DMR/YSF/NXDN/P25/POCSAG through one process, this takes the whole modem down, not just POCSAG - matches the "DMR turns red after setting POCSAG" symptom reported. The earlier commit (that added this range as green/valid) was wrong; it gave false confidence for a frequency that hard-crashes the radio service. Back to the original 144-148/220-225/420-450/842-950 ranges. --- admin/configure.php | 2 +- functions.js | 1 - 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/admin/configure.php b/admin/configure.php index 57eec28..6032499 100644 --- a/admin/configure.php +++ b/admin/configure.php @@ -208,7 +208,7 @@ $MYCALL=strtoupper($configs['gatewayCallsign']); obj.style.height = numpix + 'px'; } - +
