K3 - Dead RX after TX
Locked
 
|
Hi All,
I have been experiencing a strange problem on my K3 where the receiver is sometimes 'dead' after transmit. This seems to be tied in with the MCU control of the DSP. To prove that this is either unique or not to my unit, I would be grateful if fellow K3 owners could try this quick test. In particular I would like to hear from Beta Testers as to whether they can replicate this problem with the next (unreleased) firmware. POWER 80m LSB 3780 NOR LO CUT=0.15 SAV ALT1 NOR TX ON/OFF ALT1 TX ON/OFF Receive may be dead at this point If not continue with Select USB ALT1 TX ON/OFF Receive dead Switching bands, modes or NOR always restores receiver. Many thanks in advance. 73 Stewart G3RXQ _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

K3 newbie here. Tried to test using your sequence, but stopped at the
SAV ALT1 command. My (USA Version) K3 does not have such button(s) or entries in MAIN or CONFIG, and the Operators manual does not even have an entry for that/those commands. Help.

It would be extremely helpful for those of us who yet received our K3s that any of these concrete problem-repro cases include: SN Firmware version And hardware versions of the peripherals used. Does the Config capabilities of the K3's firmware loader provide a way to "dump" the comphrensive "I am this version of K3" including SN/Firmware #, and hardware version of the peripheral? Are peripherals like the ATU or RX come with their own SN? I will be hoping that these problems (if they are persistent) are solved by revision to the hardware and firmware. It would be good for us to regress those bugs to have access to the characterization of the system where the potential bug is found. Does Elecraft use a Gnats like bug tracking system? Any ideas on exporting the High Priority, Critical Severity bugs on the list so we can see what "it's on the list" list is ? And, for those who post to the email list here, please consider posting your debug characteristics of your platform (K3 SN, firmware version, and hardware version of peripherals) Thanks. -jeff W7BRS Order Jan-11-08 Magic 8-ball says I'll get it before Field Day...;) >> Many thanks in advance. >> >> 73 >> Stewart G3RXQ _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi Jerry:
Check the firmware Release Notes for, I think, MCU v1.75. Tells you all about it there. 73,Ken K3IU ~~~~~~~~~~~~~~~~~~~~~ Jerry Flanders wrote: > K3 newbie here.

The output file from Save Configuration includes the K3's serial number, MCU version, and the version number of the K3 Utility that created the file. Options such as the KAT3 and KVX3 do not have individual serial numbers.

Many thanks to all who responded either on or off the reflector.
It would seem that no one else can replicate the problem of RX loss after TX. Not sure where to take this now, as although there have been whispers within the Elecraft inner circle that others have reported unexplained loss of receive, I can't get a straight answer. 73 Stewart G3RXQ >> -----Original Message----- >> From: [hidden email] >> [mailto:[hidden email]] On Behalf Of Stewart Baker >> Sent: Monday, April 28, 2008 1:30 PM >> To: Elecraft Reflector >> Subject: [Elecraft] K3 - Dead RX after TX >> >> >> Hi All, >> >> I have been experiencing a strange problem on my K3 where the >> receiver is sometimes 'dead' after transmit.
