KAT100 Query
Locked
 
|
G'Day Guys,
I've got a situation that I cannot find the answer to. I have a K2/100 that I now have ( was performing HF Serive only until recently ) interfaced with a XV50/XV144/XV432 and a KAT100 and Computer. As an HF performer, it was and still is great. As a stand alone K2/100 interfaced with the XV's it was and still is fine. Now...hooking up the whole shebang, with a load on Ant Term 2 on the KAT100, when I Tx on the XV's, the SWR LEDS light up on the KAT100. Switching to Ant Term 1 on the KAT100 ( No Load ) and the SWR LEDS light right up..the whole lot, as there is no load...but that is what has me stumped ! I thought that as I am using the original, low power output BNC Connector of the K2/100 to drive the Transverters, and the radio has been told that all XV selections are a max of 5 watt output, the K2 would only output RF from that BNC socket. I have the Power Control set to 5W when using the XV's. It would appear that RF is obviously coming out the Type N Socket ( I changed from an SO239 ) on the KPA100. The XV's appear to be getting enough drive, as they Tx normally and the LEDS on their repective front panels all light up to around the 20w mark. I have re read the KAT100 Manual, and no clues in there, and my menu selections appear to be OK. I want to use the radio from 3.5 Mhz right through to 432 Mhz, which I should be able to do. All appeared "normal" till I added the KAT100...or forgot to change some menu setting ??? 73 Glenn VK4TZL _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi, Glenn:
The Owner's Manual will show you to connect the transverters to the output of the KPA100, even if you're set to an output of 5 watts (see Figure 2 on page 6 of the Owner's Manual). When you set the power to 10 watts or less the KPA100 is in bypass, but the RF is still routed to the large connector on the KPA100, not to the BNC.

Oops...typing too fast and stumbled over my words, Hi.
Clearly the RF IS available at the BNC, but that's not where you're expected to attach the load. Ignore the BNC and use only the large Type N connector on KPA100.

Glenn,
Once the KPA100 is installed, you must connect all output to the KPA100 SO239 jack - do not use the BNC antenna jack anymore. That is what the boot for the BNC connector is all about - put it on that BNC jack and leave it there. The only way around avoiding changing the connecion path from the KAT100 input to the transverters is to install the K60XV and use the low power output from the K60XV. 73, Don W3FPR > -----Original Message----- > > I have a K2/100 that I now have ( was performing HF Serive only until > recently ) interfaced with a XV50/XV144/XV432 and a KAT100 and > Computer.
