[Elecraft] KSB2 INSTALL - RX LOST
Just throwing this out there while I start backtracking to figure it out. I have installed the K160RX, KAT2, KBT2 and now the KSB2. Prior to install I was able to hear activity on the bands. After install I could hear very few stations. On the ones that I could hear, it was barely so even with full AF gain and the SWR meter would barely deflect. This AM a friend tried to TX on 40m at 5, 10 and 50 Watts. So it seems I have induced a deafness problem. I have also installed the Elecraft mic with the Rbias resister and jumpers. I was missing one jumper but used one from my computer junk box. It was slightly different as it does not have a top like the ones Elecraft provided. I include this on the off chance this might mean something to those of you far more experienced and knowledgeable than I. I have attempted to TX into a dummy load and I get dot deflections on the SWR meter in the 5-7 range but a separate watt meter indicates well below the set power. Anyway, if anyone has any thoughts on tracking down this gremlin they are certainly welcome.

Re: [Elecraft] KSB2 INSTALL - RX LOST
Chris, Track down the receive problem first - it is not related to either the mic wiring or the transmit path. The problem is on the KSB2 board. First thing to check is the orientation of the diodes on the KSB2 board - all the cathodes (marked ends) should be mounted away from the board. The second thing to check is the windings of RFC1 and RFC2 - if you scraped the wire insulation on the core when winding the toroids, the bare wire can short to the crystal cans and ground out the signal. Take a thin strip of paper and insert it between the toroids and the crystals to check for that condition. Be certain you soldered all the pins of P2 and P3 (and the corresponding headers on the RF Board). As a check on the integrity of the receive path of the basic K2, try removing the KSB2 board and insert a wire jumper between pins 1 and 3 on both J9 and J10 on the RF board. The receiver should become functional - if not, you inadvertently disturbed something on the RF Board during the KSB2 installation. If one of those suggestions does not reveal the trouble, it is time for some in-depth troubleshooting. Get out the DMM and ask about it again. 73, Don W3FPR MTcja wrote: Just throwing this out there while I start backtracking to figure it out. I have installed the K160RX, KAT2, KBT2 and now the KSB2.

Hi Glenn: FB on all this. I LOVE the idea of a hard number of paid members such as 11 for club business. All I saw was a typo or two - checks for club rather than 'cub' business. HI Also you have two instances of the word 'next' in one sentence to describe the 2 readings. Change the last instance to 'following'. We may still want to define VE session member a bit further. I believe there was a YL that passed here Tech this last time from Humboldt - technically she is an RARC member by definition. We could simply send an email to those folks upon passage of their tech stating that they would need to be at X meetings to 'activate' such a membership, or maybe just the return of the email to signify they want this membership, or some variance in between. 73, Jamie WB4YDL -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of MTcja Sent: Thursday, May 15, 2008 12:27 PM To: elecraft@mailman.qth.net Subject: [Elecraft] KSB2 INSTALL - RX LOST Just throwing this out there while I start backtracking to figure it out.

Re: [Elecraft] KSB2 INSTALL - RX LOST
Have you checked the obvious things? I feel qualified offering the following suggestions as I've made all of these mistakes myself :-) - Make sure the antenna is plugged into the right connector. If your KAT2 is connected, use one of the Antenna Tuner connectors on the back side of the top panel. If the KAT2 is NOT connected, use the Antenna connector on the back of the bottom cover next to the power connector. - Make sure the KAT2 RF cable (J7) is connected to P6 on the RF board. (I don't know if it's changed, but it used to be that the RF connector (P6) and the battery connector (P3) were the same. There are warnings in the manual about getting them mixed up.) - Make sure the KAT2 control cable (J8) is plugged into P4 on the Control Board correctly. The green wire should be at the top. 73 -- Joe KB8AP On May 15, 2008, at 10:26 AM, MTcja wrote: Just throwing this out there while I start backtracking to figure it out.

Re: [Elecraft] KSB2 INSTALL - RX LOST
This sounds a lot like a problem I had installing the KNB2 (which still isn't solved, regrettably). The cables between the top cover and the main boards of the K2 have a variety of connections, and they can get flexed in taking the cover off. In my case, the ground shield broke at the KAT2 -- somehow this allowed strong signals to leak through anyway, giving a mostly deaf K2. Resoldering the shield and removing the KNB2 restored full receive. (I'm still slowly trying to figure out what's wrong with the KNB2). Tracking the complete receive path is hard. Look first for bad connections where signals go in or out of the added modules. And keep telling yourself you'll get it working perfectly someday ...

Re: [Elecraft] KSB2 INSTALL - RX LOST
Oh, forgot about rAnt. Make sure you didn't accidentally turn on rAnt (the receive-only antenna you get with the K160RX option) in the menu. It's right next to the CAL menu item and I've accidentally turned it on while calibrating the filters. 73 -- Joe KB8AP On May 15, 2008, at 11:34 AM, Joe Planisky wrote: Have you checked the obvious things?
