K3 option questions
Locked
 
|
I am ordering my K3 sometime next week. I want to make certain that I order the suitable options when placing my order. The K3 will be factory assembled. I am not a contester. I enjoy RAG CHEWING on SSB and CW. I do not currently do any digital modes; not active on HF FM; do not normally listen to SWL; do not intend to work AM on the HF bands.
Currently own an ICOM IC-7800 and IC-756PROII. No need for a second RX in the K3 with optional filters for it. The IC-7800 already has this feature; the IC-756PROII has dual watch. I use two THP amps, HL-1.5KFX, one for each ICOM. I may switch one amp out to use with the K3. I can get the THP amp adapter cable from DX Engineering for $35. I also use a Palstar AT-AUTO ant. tuner with the IC-7800. (1) Do I need to order the TCXO-3? Is it necessary for greater stability? (2) Should I order the 2.8 8-pole SSB filter option instead of the standard 2.7 5-pole in the first RX? Will I notice much of a difference? I plan to order the KAT-3F, a 400 Hz CW filter KFL3A-400; KXV3A, K3/100-F, KFL-3A-1.8K SSB filter (8-pole); KUSB adapter; I may order KFL3A-2.8K 8-pole filter if recommended (order at the $109.95 swap out price when placing my order). I don't believe that there are any other filters that would help me operate based on my criteria above. Maybe the 250 Hz for CW, but with the great K3 PBT and high/lows cuts, it may only be another expense not needed. Since most new computers seem to have more USB ports than RS-232 ports, the USB adapter may be useful. Does Elecraft actually switch out the RS-232 jack for the USB or do they just send you an adapter cable? Any help, comments and suggestions would be most appreciated. The Elecraft Reflector seems to be a wealth of knowledge for the new or old Elecraft owner. Thanks to everyone who answered my previous post about the Heil HC-6 Pro Elite headset and the Yamaha CM-500 headset.

Note responses:
1. The TXCO-3 is not necessary. The basic TXCO is quite stable enough. 2. You will probably do fine with the 2.7 filter, but may have complications matching filters if you decide in the future to get the second Rx for diversity receive. 3. For other filters, you could get by in casual use with just the 2.7 or 2.8. Filter narrowing can happen with roofing filters or with DSP. The narrow roofing filters do a better job of filtering out noisy neighbors than DSP filtering. IF you are just casual and don't care about digging out a weak station in a crowded band, then you can save some money. That being said, having one or two of the narrow filters gives you the opportunity to test out this rig's true capability. That is worth the price of admission. 4. The KUSB is just an adapter cable. They are sold everywhere and you do not have to buy one from Elecraft. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Linda and Bob Sent: Friday, August 27, 2010 3:07 PM To: [hidden email] Subject: [Elecraft] K3 option questions I am ordering my K3 sometime next week.

If you do get the 2nd RX and do diversity, using a 5 pole filter, you
will need to order one with a matching offset. Elecraft will do that, for a small extra charge. 73, Guy. On Fri, Aug 27, 2010 at 6:44 PM, George A.
