LA-1K
Price: $3695.95Model#: 9005800
Introducting the new LA-1K RF Sensing Dual HF LDMOS 1000 Watt Amplifier. While the LA-1K will work with a wide variety of tuners and transceivers, Palstar custom-designed the LA-1K to work as the perfect match for our very popular HF-AUTO autotuner. MADE IN THE USA
New design for 2018 with gray front panel.
We are pleased to announce that the LA-1K far exceeded all standards in FCC testing at a FCC-certified laboratory and received certification for equipment authorization.

Customer Review of LA-1K:

"I received the LA-1K. Commissioning it was simple. Like the HF-AUTOs I have, it just does what it is supposed to do while looking pretty,
particularly as it sits on top of the tuner. Thank you for a great job again, Paul, and to your very good people. Vy 73, - W2BWL / M0IBD / V26WT |

[Updating the firmware requires a USB A to B Cable (not included).]
Document: LA-1K Fault and Display Notifications
LA-1K Firmware Summary:
-
V1.08S: Restrict the changing of the band or detecting a band error to a time window of about 20 ms after the PTT is energized.
When Operate mode is selected by the operator, a band cable input if any, results in the band selection to revert to the band as input through that cable.
If the remote computer control connection changes to the operate
mode, if the 4 bit band control cable is connected then the filter
will change to that selected filter, or if the ICOM voltage
control cable is connected the filter will change to that
selected filter. The AM1; command to select operate mode needs
to be sent twice when the band filter has been set to the wrong
value. (The second command to select operate mode then changes the mode)
Add the detection of additional band frequency changes that return
the amplifier to the standby mode when there is a change detected
going from one band to another band and also in direct keying mode.
The 160M 80M and 6M band changes are handled by the filter select
handling process already in effect. The Kenwood and four bit band
control will now include detection for changes between
30M, 40M, 20M, 17M, 15M, 12M, and 10M bands. The ICOM band control
cable will be able to control changes between 30M, 40M, and 20M bands.
The ICOM band control cable does not distinguish between the 10M and 12M
bands, or the 15m and 17M bands.
-
V1.08C: Allow the displayed frequency to show any changes for only 20 ms after the PTT is activated. Any changes in the frequency after that initial time window will not be displayed while the PTT remains activated.
-
V1.07M: Corrects an issue regarding false tripping of "TX Overdrive" on some units.
-
V1.07E: Allows hidden menu adjustment of transmit relay sequencing delay to correct false tripping when in direct keying mode, under certain operating conditions.Default relay sequencing delay is 1 ms. Max delay is 5 ms. The menu incorrectly indicates 2 ms through 6 ms for this setting. NOTE: LA-1Ks with serial number below 33728 should be left at a 2 ms default setting when this version is installed.
-
V1.07C: Correct occasional false high SWR tripping due to very short duration antenna disturbances such as corona discharge..
If the SWR is above 2.5:1,but less than 6:1, the SWR must be high for 50 milliseconds duration before the LA-1K trips and shows "Bypass SWR".
-
V1.07B: Increase the required raw power level required to update the frequency (avoiding problems that cause a transmission going into bypass).
-
V1.05K: Expand version 1.05E to test for the condition where the unit is transmitting only on antenna 2 or 3.
-
V1.05J: If a band change while in direct keying, change to Standby.
-
V1.05H: Expand keying status to include: 3= fault overdrive, 5= fault Id, 9= fault +Vd
Added Firmware version information to the end of the RS232 status message.
Added variable Displayed_Fault that extends the display of the condition that caused the bypass of the amplifier and that indication will now be sent as the keying status through the RS232 and will blink on the TFT display.
The indication on the display will be cleared on the next PTT or if the mode is changed.
Blank out the ALC display when displaying a fault condition.
Increase the size of the fault display, capitalize 'OVERDRIVE'.
-
V1.05E: Increase the delay switch timing when a frequency change is detected that causes an antenna change.
-
V1.05B: Allow 5MHz operation.
-
V1.04C: Remove low signal level SWR and frequency detect when in standby mode.
