[K3PZN-List] Field Day from W3CAR

Wed Jun 26 08:04:42 EDT 2013

Bill

FB - glad you got plugged into a new gang there.  I was on 40m CW a little Sunday morning, but more likely it was AC2C who was the operator, Ron, who is a pillar of the SKCC but will do any kind of CW.  Yes he is running my K2/100 into a nice inverted V that Pete made.  Sunday morning I was running stations on 80m SSB, and amongst the callers was K4CGY operating with a club.  I was pleased to operate so many different fine rigs.  NY3A visited our site but decided not to seriously operate this time.  I will gladly think with you as you start building your new antenna farm in the fall.  A new member here AH6AX/W3 wants to install an antenna soon, so we are keeping antenna equilibrium in the County.  

73 Curt

To All,

I participated in FD with my new club  W3CAR (Chesapeake Radio Service)...had a good time but missed the gang back home. It sounds like you had a another great event...very good.

I worked K3PZN Sunday morning on 40  CW...don't know who the operator was but suspect it was Curt or Steve (Ny3A)... BTW I worked NY3A Saturday evening also on 40 CW.  We used a G5RV slopped...worked great.

Best 73's

> My positioning of the beams is to blame for the QRM.  I am suspicious the path may be sidelobes bouncing off the ground perhaps.  It is not 'normal' to have 2 rigs on the same band for most operating activities -- and adding two huge beams compounds the problem.

> If one is curious, one can look up the transmit noise floor of some different rigs in the QST review.  I suggest examining this at around 200 kHz offset since this is a typical spacing between SSB and CW in the 20m band (its actually pretty flat beyond 100 kHz).  But note older reviews do not have this data.  Its NOT a major 'selling point' for rigs as rarely do operators experience this problem -- well unless a 'big gun' lives about a mile or less from your station.

> Today, I returned the generators, two 40-foot masts, bandpass filters, Heil Prosets, coax, and extension cords to the barn and club station.

> Thanks to Mike, N3VOP, for disposition of the extra food left over from FD, and for helping me lower the two 40-foot masts.
> 
> I really enjoyed FD this year and actually worked a little 40 meter SSB.  Also liked watching Kerri make all those west-coast and Hawaii contacts on 20-meter SSB using my new rig.  Sorry the rig was responsible for jamming WX3B's efforts on 20-meter CW.  Next year we should try spacing the beams further apart and/or try a different rig if we still have the noise issue.
> 
> Andy:  When you get your new spectrum analyzer, I'd like to compare the broadband noise output of the FTdx3000 versus the K3, and/or any other rig we might want to compare.  Might save us more issues like this at FDs in the future.
> 
> Does anyone know where the manuals are for the two Honda generators?  The older generator still surges a bit at light loads.  I'd like to clean the carburetor before making mixture adjustments.  I checked the club's file cabinet and the manuals were not there.
