Re: [Elecraft] What crystal filter do you use the most?

I am one of those folks who has the INRAD 700Hz filter (special-ordered by the guys at UNPCBs, http://www.unpcbs.com/). I use it exclusively for scanning the bands on CW. When I want to get tighter, I have the 400Hz filter below that. I've found that combination works wonderfully for me. For SSB,

Re: [Elecraft] What crystal filter do you use the most?

Bob, Good comments. I think those of us who have been in ham radio for many years still think of physical filters as doing the job of specifying the radio bandwidth and forget that today's radio often is digital or partially digital where DSP does the job and filters are only used

Re: [Elecraft] What crystal filter do you use the most?

Here 400 Hz on CW, 2800 Hz mostly on CW -- though I have the 1000 Hz filter for tuning on CW and one tighter one (2100 Hz) for more crowded SSB situations. If budget had been a concern, I'd have gone with 400 Hz and the stock 2700 Hz pair. 73, Phil W7OX On 9/28/15 12:35 PM, Dan Atchison

Re: [Elecraft] What crystal filter do you use the most?

Being 95% CW and only sometimes on SSB I use almost all the time 500Hz 5-pole filter. I have 200Hz but use it very rarely. This is just my experience since beginning of K3 history. 235 countries in QRP in 2 years, all States, all Oblasts. BennyOH9NB --- Avast Antivirus on tarkistanut tämän

Re: [Elecraft] What crystal filter do you use the most?

The advice I received was to try the radio stock then select what I needed. I didn't want to deal with offsets or aligning filters when I eventually get the sub RX. Because of this I opted to upgrade to the 2.8KHz and purchased the 400Hz on this list. When I get the sub rx I'll buy 250Hz x2,

Re: [Elecraft] What crystal filter do you use the most?

On my K3 I have an LP-Pan connected to my IF out on the main receiver and a FunCube Pro on the subreceiver IF out. The LP-Pan is setup to a Steinberg USB UR22 sound card. Therefore, I have two panadapters, one through Win4K3 for the main receiver, the second using NAP3 v5 to the funcube pro.

Re: [Elecraft] What crystal filter do you use the most?

The lineup here is: 2.7 & 1.9 for ssb, 500/8pole and 200/5pole for cw. I'm seldom on ssb, 95%+ on cw, so can't say anything useful for the first two filters. I use both of the cw filters as conditions and circumstances dictate. The 500cps filter is first choice and does most of the work here.

Re: [Elecraft] What crystal filter do you use the most?

I have 3 roofing filters, 400Hz for CW and digital, 2.8kHz for SSB and 13kHz for listening to broadcast stations. But I should have selected 500Hz 5-pole and 2.7kHz 5-pole instead of 400Hz and 2.8kHz. I have very strong local power line noise, often S3 to S5 level. Steep filter like 8-pole

[Elecraft] What crystal filter do you use the most?

This is an interesting discussion. Before I purchased my K3 in 2008, I had become addicted to narrow selectivity with my previous rigs, and was routinely tuning the bands with cascaded 250 Hz filters. Since I'm nearly 100 pct. CW, I purchased a range of crystal roofing filters to try out in

[Elecraft] What crystal filter do you use the most?

I'm with W4TV on the 5-pole 200 Hz filter as my overall go to on close in CW sigs. The 8-pole 250 Hz filter, which I also have, is actually about 350 Hz in width and way too wide for me. That said, I use either a 500 Hz or 400 Hz filter most of the time on CW/RTTY It is unfortunate that

Re: [Elecraft] What crystal filter do you use the most?

Again and again, we all encounter signal conditions where a very weak wanted signal is close to a very loud unwanted signal. For this the best filter setup is where BOTH the roofing and the DSP filters are at the desired operating bandwidth. That is why for CW contesting, in pure self-defense,

Re: [Elecraft] What crystal filter do you use the most?

> What filter do you find you use the most and why? The 400 Hz filter as it works well for both CW and RTTY. If I were not so concerned about RTTY, I would consider the *INRAD* 500 Hz (8 pole) filter for CW along with the 200 Hz (5 pole) Elecraft filter for times when adjacent signals are just

Re: [Elecraft] What crystal filter do you use the most?

Ken makes a pertinent comment; "the DSP does all the rest". Suggested filters are roofing filters and serve a function of signal path and how signals outside of the DSP bandwidth can affect the receive performance. Receiver selectivity is actually accomplished by the DSP engine. Regarding

Re: [Elecraft] What crystal filter do you use the most?

I would think it best to get the K3S and see how it performs before throwing money at a problem that may not actually exist. Adding filters if and as needed is rather simple. 73 Bob, K4TAX K3S s/n 10,163 On 9/28/2015 1:15 PM, David Cole wrote: Hi Mike, I understand it is a roofing filter...

Re: [Elecraft] What crystal filter do you use the most?

The filters you guys are discussing are roofing filters. The filtering you're thinking about is done digitally, and is continuously variable. The K3s isn't your Dad's analog rig. Here's an Elecraft article explaining roofing filters. http://www.elecraft.com/K3/Roofing_Filters.htm 73, Mike

Re: [Elecraft] What crystal filter do you use the most?

Hi to the Gang This is a subjective question but after using a 500 hz and 200 hz filter for 7 years I ordered a 400 filter for my K3s. The main reason is it works well for both CW and RTTY and of course the DSP does all the rest. I also ordered a 2.1 khz filter so if I go past 400 hz I get

Re: [Elecraft] What crystal filter do you use the most?

Hi, I use the 400 Hz filter for CW, and would enjoy a 1 KHz filter I believe... The 400 is just a touch to narrow for my tastes. It works well in crowded conditions, and I would not want to get rid of it, but a 1 KHz might get more use... -- Thanks and 73's, For equipment, and software setups
