Hi Skip, I am quoting here my reply to DAVE about his Anti-radiation missiles tuned to PACTOR PMBO frequencies for your information! That shows you exactly the attitude of some people against anything they dislike and how they act. If the Pactor PMBOs activated any DCD mechanism, people like Dave would sit there all day to deliberately cause QRM with their Anti-Radiation missiles tuned to the PACTOR PMBO frequencies, as he said, and cause havoc. Is this kind of QRM accepted by you? What about this Skip? Is this justified? Tell me what works perfectly on HF and if we manage to correct them all then PACTOR will follow and I believe the PMBOs will have no problem finding a way to implement a DCD mechanism. And just like Andy, our moderator, said previously: ------------------------- Aside from Pactor, I suspect that many ALE operations are not always under full manual control. Neither are some Propnet stations that use 300 baud packet or PSK31. Many DXpeditions act like they can transmit any place they want, and then there are also the folks at W1AW who send old news automatically at predetermined times via RTTY and CW. -------------------------- And I must add, what about the numerous nets on HF that deliberately cause QRM when anyone dares to use their frequency before they start their NET? What about AX25 BBS FORWARDING that still takes place on HF? (These are really the automatic ROBOTS, not the semi-automatic PACTOR PMBOs), what about HF APRS Digis? What are you going to do about all them? Fix the HF bands first and then blame PACTOR PMBOs and automatic operations. Forget about PACTOR 3 being the problem because it isn't. 73 de Demetre SV1UY ------QUOTED MESSAGE From Dave------------------------- Re: Questions on digital opposition, QRM on PACTOR PMBOS now from DAVE, Congrats --- In digitalradio@yahoogroups.com, "Dave Bernstein" <[EMAIL PROTECTED]> wrote: > >>>QRM from PMBOs and other deaf robots spoils the enjoyment of > amateur radio for many operators Demetre.

You see now why the PBMOs cannot install any DCD mechanism that detects QRM and they leave the busy detection to be the responsibility of the client? Because people like you would misuse such a mechanism and the PMBOs would be rendered useless. This is a VERY bad practice that you and your followers excercise and hence you should have your license revoked for this action you just admitted yourself. Anyway please comment to your daddy (the FCC) as you like, although you do understand you are wrong, and if you have a PACTOR MODEM and have not understood it's use yet then I am sorry for you because nothing comes even close to PACTOR 3 for emergency comms OM. > 73, > > Dave, AA6YQ > 73 de Demetre SV1UY ------END OF QUOTED MESSAGE-----------------------------------------
