[Elecraft] K3 upgrade to K3S question

Hello list, I've purchased a used K3 S/N in the 3ks, and plan to apply some of the K3S upgrade options. Any experiences, hints or do's and don'ts to tell for me? I'm using the K3 mainly for HF contesting, VHF with an external transverter and some DX chasing. tu es 73 Gernot, DF5RF __

Re: [Elecraft] K3 upgrade to K3S question

There are two upgrade issues to consider: (1) The recommended modifications to bring your K3 up to the latest engineering level. Check for what you may need and how to install it. (2) The upgrades to install the new K3S upgrade boards. The big w

Re: [Elecraft] K3 upgrade to K3S question

Gernot, When changing the synthesizers, the major concern is dropping the lockwashers behind the existing mounting screws. To avoid that, loosen the screws almost all the way but not quite out of their threads. Then tilt the board toward the rear and push the lockwashers as far onto the screw

It is easy to do and well worth the small amount of time and the cost. Doug -- K0DXV On 3/11/2017 3:57 PM, g...@gmx.net wrote: Hello list, I've purchased a used K3 S/N in the 3ks, and plan to apply some of the K3S upgrade options. Any experiences, hints or do's and don'ts to tell for me? I'

The KIO3B has both RS232 and USB. All 3 upgrades are easy to do together.  Now takes me less than 30 minutes total for 2 KSYN3As, KXV3A and KIO3B. 73, Ed W0YK On Mar 11, 2017 4:41 PM, Bill Frantz wrote: > > There are two upgrade issues to consider: > > (1) The recommended modifications to brin

Re: [Elecraft] K3 upgrade to K3S question

I consider that a real bargain for upgrading a 2008 vintage radio (when the K3 was introduced) to a 2015 vintage radio. Compare that with the cost of upgrading a YaKenCOM rig -- buy a new one. 73, Jim K9YC On Sun,3/12/2017 8:48 AM, briancom wrote: and almost a kilobuck Sent from my iPad O

Re: [Elecraft] K3 upgrade to K3S question

When faced with the upgrade question, my choice for spending the money was to try out the IC-7300. I wouldn’t contend that the IC-7300 is equal to the K3S/P3, but the K3 and the IC-7300 combination may be more fun than the upgraded K3S for the same money. Jimmy Walker WA4ILO Macon, GA On Mar 1

Re: [Elecraft] K3 upgrade to K3S question

The synthesizer upgrade makes a huge improvement in any medium CW speed operation and gets rid of a slight irregularity in CW formation when keying slower tx/rx transition amps. That's in addition to the superb lowering and narrowing of phase noise. I have this half notion to get a single rx K3 w

Re: [Elecraft] K3 upgrade to K3S question

Bill, Good to know there is a DSP Update - didn't recognized it yet. Rev C is installed so the only difference to Rev D is the 4 kHZ Audio LPF. Did you encounter situations with a noticable enhancement using the LPF? 73 Gernot, DF5RF __

Re: [Elecraft] K3 upgrade to K3S question

Bill, thanks for pointing out to option (1). After reading all the suggestions I will very likely do the KSYN3A upgrades only. Regarding the USB/Sound card - I had to insert ground insulation for all the Audio/USB to PC connections to avoid ground loops. Does anybod know if this one is already

Re: [Elecraft] K3 upgrade to K3S question

Gernot, The DSP board upgrade did two things. It added a Low Pass Filter to reduce the high audio filter response which eliminated some high frequency 'hiss' that some operators objected to. Secondly, it changed some capacitor and resistor values which enhanced the low frequency response.

Re: [Elecraft] K3 upgrade to K3S question

According to the Elecraft website, the rev C DSP board introduced the low frequency improvements that were then carried over to the rev D board. So if you add the LPF module to a rev C (a simple addition), you have the equivalent of the rev D without the need for a board swap. > > > You can
