[Elecraft] AF-1 audio filter

Hi, With all the chatter about the AF-1 audio filter lately I thought i would post how I mounted the AF1 and an audio amplifier in a small case to use with my K2. If anyone is interested you can find the pictures and comments on my web site at lawrenceingram.com. Click on the Ham Radio tab

Re: [Elecraft] AF-1 audio filter

Ron, Thanks for the complement; I enjoy seeing what I can do to make something fit my needs. I don't have a particularly noisy site but I have the radio sitting on a shelf with another shelf just above it which makes the top firing speaker in the K2 more difficult to hear. So I added the

Re: [Elecraft] AF-1 audio filter

Hisaahi, I have used both and find both useful. The thing I like about the AF-1 is the ability to shift the peak frequency. 73, Larry Ingram AG4NN At 12:34 PM 12/1/2010, you wrote: I wasn't paying enough attention lately. Does anyone have a comparison of the audio filter in the AF-1 vs the

[Elecraft] K3 - ATU Tune

Hi, Something curious has happened to my K3 SN 3975 - when I tap the ATU Tune button the power out shown on an external power meter is full power, a little over 100W. The K3 power out indicator also kicks up to full power. I have the unit set to 50W and when I key it normally (CW) it shows

Re: [Elecraft] K3 - ATU Tune

Well my indulgence at the Orlando hamfest arrived yesterday - a new K3. This means I need to find a new home for one of my K2s - or my wife may decide to find a new home for me. I have a K2/100 plus the external KAT100 for sale. The K2 serial number is 6405. The KPA100 is older but all the

Hi, I received a note from Don W3FPR and Hank K8DD about the problem I posted the other day where even when I just tapped the band up button on my recently built K2 it would sometimes go into the RCL mode. First I want to say thanks for the suggestions and then tell you what I found in

Hi, I recently build my second K2 sn 06405. Receiver and transmitter are working fine and I have enjoyed a number of QSOs on 40, 30 and 20 meters and the rest of the bands have been checked out with a signal generator and transmitting into a dummy load. However, occasionally when I go to

Re: [Elecraft] K2: Various Receive Problems

Jon, I wonder if you are tuning at the fastest rate - at that rate the signals would seem to jump in and out as you are describing and since they would not be in the center of the filter passband most of the time it might explaing the seeming lack of sensitivity. Larry Ingram AG4NN At

There have been several comments on enclosing (or not) the W1. I built one into a small metal enclosure to have something that looked nice on the shelf with the K2. I have put pictures on my web site (just getting that up and running) at http://www.lawrenceingram.com If you have any

[Elecraft] K2/K60XV problem

Hi, I installed the K60XV in my K2 and while checking the output I discovered that when I increase the power control the output follows the control until I reach about .85 mW out then the output jumps to 2.7mW and stays there. When I bring the control back down, the output remains at 2.7mW

Perhaps the enhancement could be a BFO that is adjusted by a front panel control? This would be nice, and I presume that you mean that the knob would maintain the location of the BFO in relation to the passband along with the sidetone pitch. Currently it's possible to adjust the pitch from
