Let me first say that it's a pleasure to have a conversation with you
for a change. That said... you are certainly entitled to you opinion on the SSB delay. A switchable delay is really quite subjective. If you really had a problem with the SSB delay... you could opt for no delay and use the SkyWave's multiplexed "hard" keying feature. This allows keying the amp when the mic is depressed (in any mode) and holding for as long as the mic is pushed. It requires a slight mod to the radio... but no extra wires between radio and amp. Many of the hams running the SkyWave are using this feature. www.telstar-electronics.com DrDeath wrote: "Telstar Electronics" wrote in message ups.com... You are correct... there is one delay for both modes. As the designer, my feeling is that a switchable AM to SSB delay is not necessary. As a consumer I feel it is a necessity. My experience has been that a reasonable delay can be chosen that is acceptable to both modes. I disagree. Maybe the average Joe Blow doesn't mind a slow AM delay or a SSB that chatters, but I do. Actually, a slight delay in all modes has a distinct advantage when the amplifier is mounted in a remote location such as the trunk of the vehicle. It allows the operator to confirm that the amplifer was pulled in on the last transmission by numbing the receive (during the delay) for a very short time after the mic button is released. Without this effect, the operator has no real way of confirming the amplifier is operating to some level, since the relay can't be heard. You add a LED to the remote switch tie it in with the COR circuit, problem solved. |

oups.com... Let me first say that it's a pleasure to have a conversation with you for a change. I would rather discuss technical issues instead of the constant nonsense that gets posted daily. We possibly could have gotten off on the right foot if you hadn't been spamming the group when there is a group just for listing your items. Your tag line is more in keeping with Usenet manners (as is bottom posting, but I'm not that anal). That said... you are certainly entitled to you opinion on the SSB delay. A switchable delay is really quite subjective. Let me pose this question. Why would most amp builders put a delay in if it were not necessary? From the old tube boat anchors of the past to the modern units of today. Last winter I built an EB63 and attempted to do the same thing and I ended up switching the delay as I could not find suitable middle ground. Maybe I'm just picky, but I like my equipment to respond in a certain way. If you really had a problem with the SSB delay... you could opt for no delay and use the SkyWave's multiplexed "hard" keying feature. This allows keying the amp when the mic is depressed (in any mode) and holding for as long as the mic is pushed. From what I see, your unit has a COR circuit, which means that it must sense the carrier. How is the relay operated in SSB mode with no modulation or carrier? Are you sending a modulated signal in SSB mode or are you adding a small amount of carrier to the SSB? Something is operating the COR circuit, how about pointing out what that is so I don't have to restudy the design. It requires a slight mod to the radio... Like???? Give me an example of what I need to modify in my 148. but no extra wires between radio and amp. A two pill really doesn't need to be remotely operated, I just gave that as an idea for those that might want it remotely mounted. Many of the hams running the SkyWave are using this feature. Most hams that buy your unit will never use it on AM. |

The only spammers are you and the dam tard and mope-a-dope! you couldn't change a tube much less build an amp you dumb cb'er! |

I'm certainly not saying that you don't need a delay on SSB... and you
sound like the length of the delay (for SSB and no delay on AM) is a priority for you. That's fine. That's why you would need to use SkyWave's mutiplexing keying feature. If you send me an email... I would be glad to send you the details of the mod for the radio. Keep in mind that this mod doesn't work for other brands of amplifiers. It allows the amp to key (in any mode) when the mic is pushed... no matter if modulation is present or not with no extra wires between radio and amp. www.telstar-electronics.com Let me pose this question.

ups.com... Email sent... I looked at it, my opinion is that making changes to my radio in the final output stage by adding a ferrite coil could compromise my outgoing signal. I nor most of your customer base own a spectrum analyzer. The parts you list cost no more that the switch and cap you could add to the amp for the delay. In fact, if were to own your unit, that's where I'm putting my $3 worth of parts. I'm not trying to slam your product in this thread, I just wanted to share my opinion as a consumer. If you think the consumer does not want an adjustable delay then by all means go with what you have. |

As far as compromising the output signal, hanging a choke plus a 1K
impedance on the output will change nothing. Many people are using this feature (along with myself) with no performance shift. I think your idea of a switchable delay is fine... I just think the extra cost of instituting it is unjustified... given the extra cost... and the lack of complaints of the current design. But thanks for your input... www.telstar-electronics.com DrDeath wrote: I looked at it, my opinion is that making changes to my radio in the final output stage by adding a ferrite coil could compromise my outgoing signal.
