[digitalradio] VOX Delay / Signalink interface ALE-400-ARQ-FAE
All, The ALE-400 ARQ mode uses a relatively fast transmit / receive turn around. Excessive PTT hang time will block incoming ACKS from the other station and results in an endless loop of TX/RX exchanges without any data passing through. The Cure: 1. If you have a Signalink interface, make sure the VOX delay is as short as possible using the delay button located on the front panel. 2. If you have a Kenwood TS2000, make sure the VOX delay is off by clicking FUNCTION KEY on the front panel. Many rigs use VOX delay so please change this setting to read OFF. Thanks, Tony -K2MO

Any suggestions for a amp vhf for SSTV I inquired with MFJ...and they said NO, for sstv on their line of amps. Any help appreciated... POB/K8LEN

Jaak, Overdriving your audio into the rig causes your intended transmitted audio in the passband to go non-linear and put images out all over the waterfall.

Re: [digitalradio] SSTV AMPLIFIER
Is this for a FM or SSB transmitter ? If FM then any amp should do. If you are using a SSB transmitter and feeding it the audio for SSTV then you need an amp that is linear. I would guess that most of your sstv transmissions are not too long (say less than 30 seconds) so the duty cycle should be low. - Original Message From: obie47165 obie47...@yahoo.com To: digitalradio@yahoogroups.com Sent: Mon, May 24, 2010 9:10:19 AM Subject: [digitalradio] SSTV AMPLIFIER Any suggestions for a amp vhf for SSTV I inquired with MFJ...and they said NO, for sstv on their line of amps.

[digitalradio] Re: What mean Too Wide?
An example of too wide will be too much audio (mike gain)drive on an SSB signal. This results in splatter over other signals which are near. The same in PSK, but here you can see the splatter as a wide signal. --- In digitalradio@yahoogroups.com, KB3FXI kb3...@... wrote: Jaak, Overdriving your audio into the rig causes your intended transmitted audio in the passband to go non-linear and put images out all over the waterfall.
