Dear Martin, I've ordered some days ago... and received yesterday the 6Khz for AM & ESSB and the 1.8K for SSB. So I installed them yesterday evening. Considering my antenna, delta loop for 40m and the huge signals received for the ex-USSR side, 59+30 & up is common, the 1.8k in addition to the 2.8k is really helpful and I like the fact when moving the width knob it goes automatically from one filter to another. Just an example from yesterday as I made rx tests after installing the 1.8K, 2 x UA big guns were on 7.085 and 7.090 respectively and polluted the spectrum with very bad tuned amps with lot of splatters. With the K3 and the 8 pole filters I was able to distinguish and follow a qso on 7.088 performed by 2 M0 Hams. The shift was reduced on 1.00 and the bandwidth 1.6~1.7 with the 1.8K activated. Using the AFX for audio was also helpful. Considering my cw traffic, the 400Hz is perfect for general purpose. My actual config, all 8 poles filters Main FL1: 6K FL2: 2.8K FL3: 1.8K FL4: 400Hz Sub: FL2: 2.8 FL4: 400Hz Bst 73's & Happy New Year. Philippe A65BI (F5LTB) K3#3616
>>> Martin Schmiedel <hamra...@vr-web.de> 28-12-2009 4:00 >>> Elecrafters, i am about to order filters for my K3 and would like to hear from the group what filters i should go for. I am a ragchewer as well as a contester, ssb & cw. Rarely data modes. I do weak signal work on 160/80 cw. I have 2.8khz ssb in main & sub 400hz cw in main & sub Should i order the 200hz 5-pole filter for their narrower bandwith or the 250hz 8-pole with steeper skirts? Add 2.1khz or 1.8khz for ssb? What is your recommendation? Should i add filters for both rx's (-> diversity) ? If i go for the 5-pole filters,should they be matched by elecraft or is there a method to tweak it in the K3 ?
