In this bulletin I send an excert of the manual of TFPCX 2.71 which shows how to work with your squelch open with TFPCX 2.71. EX.: When using Graphic Packet edit the config file and add a line with: TNCINI = @C25 This will activate the Soft-DCD. You should try other values, if you have problems. For more info, read the information below.

March 1998) Resident AX.25-Controller for PC and BayCom-Modem, SCC-Boards, PAR96, YAM96 PA0HZP-OptoPcScc Board, KISS with WA8DED-Hostmode-Interface and DRSI cards @C DCD-Working TFPCX has a Soft-DCD (software squelch). When using slow tranceivers (slow meaning a slow squelch cirquit) you can leave the squelch of the receiver fully open. TFPCX will determine for itself whether or not a packet signal is being received. The Soft-DCD can be controlled by means of the '@C' command, the given parameter controlls the noise-cancelling level. This parameter can be a number between 0 and 63. When using '@C0' the Soft-DCD is switched off (default)- all other values activate the Soft-DCD. The lower the value the more unstable and faster the Soft-DCD becomes, the higher the value, the more stable and slower it becomes. The ideal DCD should be both stable and fast. Therefore the best setting will good compromise between the two extremes. To simplify the job of finding the right value you can use the DCD indicator (see option '-C'). When using a small value you will see the unstable DCD indication, when using a large value you will see slow and inaccurate recognition of signals. The best way to set this correctly is to slowly increase the parameter value while listening to the signals on the PR QRG, until the indication is correct. A good start value is '@C25'. When using SCC, PAR96 or PICPAR ports an adjustment is not really needed, all values above 0 will activate the Soft-DCD and they all have the same meaning for the operational software. I was, however, annoyed by the constant flickering of the indicator, so you can still adjust the value to reduce the flicker. For the YAM96 modem the @C command will not work at all since it always uses a hardware DCD. IMPORTANT! The soft-DCD only recognises PR-Signals at the same baud rate. You can _not_ use the soft-DCD on packet QRGs which carry PR signals at different baud-rates. When using KISS, the TNC handles the DCD, and this command only defines the time (in 10ms-Units) after which the RX indication will be removed from the screen if no further data was received from the TNC. When you are connected to a DAMA station the DCD will be ignored for the used port. The DAMA station will regulate the traffic and will ensure a free QRG when it sends a DAMA-poll to you, so TFPCX doesn't need to double-check this. The advantage is a very fast response from TFPCX, which makes the DAMA handling better. This was introduced with TheFirmware TF2.7b, and is also used in TF2.7b based TNCs.
