Re: [Elecraft] Filters for weak signal 160 meter CW and crowded contest bands
-Original Message- I wish I could vary the pitch of a signal directly while listening to it, instead of having the sidetone cover it up. 73, Drew AF2Z Me also. I use different pitches depending on what I'm doing. Higher for casual QSOs, lower for contesting pileups. It helps spread out closely packed stations. Ditto the sidetone volume. I require several volume settings depending on which speaker or headphones I'm using and by the time I realize that I have it wrong I'm in the middle of a QSO and can't change it without drowning out either myself or the other station. 73 thanks for listening Carl WS7L K3 #486 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I wish I could vary the pitch of a signal directly while listening to it, instead of having the sidetone cover it up. 73, Drew AF2Z Excellent suggestion Drew. My IC-765 has that feature (as do many rigs), and I recently forgot how much I depended upon it until I sent my K3 into Elecraft for upgrades, and started using the 765 again. It does fine tune in real time for the best CW audio/sig strength on the 765, much better than the K3's implementation for me. I wonder if the Elecraft folks can offer that feature in the future? 73 Gary NL7Y ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Dana Roode wrote: I've seen lots of discussion about K3 filters so here's my question. I've got the 400 hz 8 pole filter and it works well. During the ARRL 160 contest I had trouble running due to someone else doing so about 300 hz up the band. I was thinking about acquiring either the 250 8 pole or the 200 5 pole. Any thoughts? I have not seen any data on the 200 hz filter, but the 250 seems more like a 370 hz filter if you look at the filter plot. Which do I want? Probably the 200 Hz. You're correct about the 250 which is only ~65 Hz narrower than the 400 (which is actually ~435 Hz if my memory is correct). My 200 measures ~205 Hz at the 6 dB points so you would notice more of a difference with it even though it has wider shoulders (i.e. 5-pole instead of 8-pole). I have both a 500 and 200 and use both on 160. Normally I prefer the 500 but there are times when the 200 is very nice to have...such as in a large nearly simplex DX pileup with lots of strong stations calling. I would normally not want to use the 200 in a contest, because I would miss the guys calling off-frequency, but it's nice to have it available when necessary. Someone else asked about the filter plots on the Elecraft and Inrad websites. I believe all of these were made by George W2VJN before he sold Inrad to N5KO and AG9A. I hope Elecraft or Inrad might ask George to graph the missing filters (all 5-pole and some 8-pole) eventually (including the yet to be introduced variable bandwidth filters). If George cannot do it perhaps Jack K8ZOA could do this. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/Filters-for-weak-signal-160-meter-CW-and-crowded-contest-bands-tp2154048p2157401.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I was thinking about acquiring either the 250 8 pole or the 200 5 pole. Any thoughts? Dana, K6NR Hello Dana. At my noisy QTH in Fairbanks, I often use the 200 Hz filter at a BW of 100 to 200 on 160M. I have both the 500 and 200 filters, but to get the QRN down, and maybe improve the S/N, the narrow filter and setting is best on what is often weak DX for me. On my small city lot I use a rotatable receiving loop (Wellbrook), which can hear better than my Inv-L most times. Also play with the AGC Slope (~3), Threshold (~6-8), CW pitch (~450-600 Hz), and filter insertion loss compensation (~4-6 db) to peak the weak sigs. I put the AGC settings on the PF 1-2 buttons for ready access as changes are often required depending upon the condx. 73 Gary NL7Y ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
