Good question :) you can use any of the modes on any of the bands , as long as the rx is set the same .... all are the same on/off keying , time is used to set the s/n level , I think the 30 second version is optimised for hf>vhf , but will work on the lower bands First option ) If you use the CAT option then the band and qrg is pre-loaded , this mainly applies to the VHF/ HF bands Second ) Use the nominated frequency and use audio drive SSB tx/rx , then the system is auto configured , ie , I set my exciter to 500.00 usb and the Rx to 500.00 usb and use audio drive. Third) If you need to select your TX frequency and use com-port ptt drive , then the normal operation is to use a carrier off set , based on the USB dial set frequency , this enables remote monitoring stations to be on frequency and intercept below the noise signals . Depending on OP8 or OP32 , the carrier needs to be off set to ensure the correct audio frequency range at the Rx But , yes as in Pete's test to day , monitoring stations can simply re-tune to accommodate fixed Tx tests. this also happens when Joe vo1na uses OP on 507.77 ( fixed allocation) Distance OP8 , well I think that may be held by Gary g4wgt and Joe vo1na at 3500 Kmts , on 136 Khz Gary using 400 watts to a 12 mtr top loaded vertical , later Gary also decoding Joe. Quite regular decodes from ra3agc into the uk have been reported with inter Russian decodes 100% over land using OP8 mode and more recently , OP32 is being used , adding another -6 dB to the minimum decode level , Op8 -32 dB (-38wspr) OP32 -38 dB (-44 wspr) 73-G. -------------------------------------------------- From: "Stefan Schäfer" Sent: Saturday, June 02, 2012 8:12 PM To: Subject: Re: LF: Re: Opera... > Hi G.., > > Am 02.06.2012 20:02, schrieb Graham: >> >> 136 is provided with two beacon speeds only , OP8 and OP32 , >> changing mode , changes the frequency band. monitoring is one >> speed only . > But if the PC simply keys the PTT then how does the program know on which > frequency i choose on the TX?
