[Elecraft] K2 - removal of Digital Filter board

I am trying to tace a 2 x S point loss in my receiver. I want to remove the digital filter to remove that as a possibility. What pins on the control board do I put the jumpers - I cannot find this in the manual. I am off on holiday to Spain tomorrow and will take the K2 with me so that I

I brought in the full package (K2/100 ATU100, DSP, 160M SSB). The Customs actually rung me up to find out what it was. The expensive package may have attracted their attention but it did reduce the shipping and postage. However it worked out that dollars in the States arrive as pounds

[Elecraft] K2 4817

I am pleased to tell you all that I made my first contact yeaterday for 15 years. I became deaf over night and immediately packed up Amateur Radio. One year ago I decided to try and start again and bought the K2 kit, with all the accessories (except Transeverters). My first contact was

Thanks Dudley - My mate carried out a series of test (when he heard I had gone deaf) and he reckons (surprisingly) that the thumb is the most sensitive spot. There are others places I can think of but unfortuneately some of them were damaged at the same time as my hearing nerves when

[Elecraft] Re: Elecraft Digest, Vol 20, Issue 22 Headphone for hard of hearing

I am interested in determining which earphone (or speaker) would have the highest physical movement. I am deaf and intend to read morse by feeling the vibration. Once I have found the earphone/speaker, I then have another problem. I suspect I will have to find the K2's best audio that

[Elecraft] Headphone for the hard of hearing

Thank you one and all for your prompt and helpful replies. To sum them up - 1. It will be bad news if I remove the paper from a loudspeaker - it will stop working. 2. A visual method of reading morse would be helpful but I would rather use vibration, but visual and vibration would probable

[Elecraft] K2/100 HI CUR

I have enjoyed reading the problems of others but now its 'the winter of my discontent' as they say. I've successfully built the K2, KSB, 160 converter, DSP and finished the ATU (needs testing and not connected). I am now finishing the K100 I have got to the end of the test where one fires

[Elecraft] Re: Elecraft Digest, Vol 18, Issue 25 - Stripping coil windings

I have a pair of wire strippers - they are shaped like nail clippers but are flexible and therefore limited the amount of pressure such that it cuts through the varnish but not the wire. However I also use heat - not enough to burn off but sufficient to make the varnish brittle. Withe the

Bear in mind that many of the chassis screws are used to secure 'earthing joints'. The use of a lubricating oil or copper slip will indeed reduce electolytic corrosion but may well also introduce some resistance, as all lubricating oils/greases will leave a thin skin even under pressure.
