Hello All, In my post on radio control and PC-ALE earlier I should has mentioned a few other items.
Obviously any can place their radio into SPLIT VFO when PC-ALE or any program (ScanCat, BeaconSee etc.) is directly controlling frequency scanning where you want the program to be under PC control to stop on a dime when a signal is detected for whatever purpose and yet you do not want to unduly tax the radios hardware. However, for ALE purposes, both VFO's need to be on the proper frequency when it comes time to transmit, thus when you are Scanning and a station calls you to establish an ALE link, only the RX VFO will have been updated and you will transmit back on the wrong frequency. Again, PC-ALE handles this for ICOM radios where it works, those not listed for selection can by used with the GENERIC ICOM interface. Having said that, the current PC-ALE does something with respect to Kenwood radios that make then a viable option Scanning with ALE and being on the correct frequency to transmit should you receive a call, it writes the channel frequency to both VFO A and B. Thus if you manually place the radio in SPLIT VFO for use with PC-ALE, any CAT Kenwood HF will be on the correct frequency for RX and TX when a link is achieved. However, all but the older Kenwood TS-440 work correctly, for that model the BPF relays are not disabled during RX Fo changes. The only two Yaesu radios that support QS/S are the FT-990 and FT-920, however the current PC-ALE does not write to both VFO's for either of these models or any others. In addition for monitoring only purposes a general coverage receiver can be used can be used instead of a transceiver (some receivers also have relay issues, but they are not as critical as in a transmit and some provide CAT commands to bypass) where RF power relays are not a consideration. I have a TCI 8174 DSP receiver that runs 24/7 here using MARS-ALE. Anyone can download and use MARS-ALE for monitoring with, it has support for lots of receivers as we use them for guard channel duty where a transceiver is not required. In addition, I will be marrying transceivers to work with receivers in a twins configuration in a future release of the tool for a number of reasons. /s/ Steve, N2CKH/AAR2EY www.n2ckh.com Need a Digital mode QSO?
