[Elecraft] K2/100 RS-232 Noise

Hi Pierre.. YES, I did leave the freq counter cable. Is that the problem? I'm at work right now and can't test it. Thanks.. David, W4SMT David, I just wanted to know if your cable was still in place before opening my K2. I have the same noise problem, especially on 20 m, and guessed that the

[Elecraft] K2/100 RS-232 Noise

From David W4SMT However I'mgetting some annoying noise from the RS-232. My software polls the K2 every 250ms (4 times per second) and it generates noise on all bands every time it's polled. Hello David, Did you left the frequency counter test cable connected to TP2 (BFO)? 73 de Pierre VE2PID

[Elecraft] K2/100 Final Berillium transistors

Hi to all, As mentionned in the KPA100 manual, Q1-Q2 2SC2879 contain Beryllia Ceramic. Do not break, cut, or crush them, since the dust or vapor can be dangerous. However, there is a new design, the 2SC2879A. The difference between the 2SC2879 and the 2SC2879A is that the "A" version is RoHS

[Elecraft] KPA100 RFC10 choke

Well, I think that the removal of RFC10 is adding a risk to this fine rig. To rely on external protection (at the antenna or at the transmission line is risky at best.. As far as I know, all major brands (Icom, Yaesu..) are providing the extra protection given by an appropriate choke inside the

[Elecraft] KPA100 RFC10 choke

Hi, I built the 100 W PA about 15 months ago. There was a choke across the antenna jack at J2, to prevent build-up of any static charge at the antenna jack. However, I see in the latest manual of the PA that this choke is not shown. Any reason for it? 73 de Pierre K2/100 # 5170

[Elecraft] Coaxial switch and two rigs

Hi Elecrafters.. maybe that question has already been posted, but I ask it again. I plan to use an IC-706 MKIIG for SSB/VHF operations and a K2 for CW only. I have a Daiwa CS-201 coax switch. The ''output'' of the switch will go to an ATU (LDG AT-100Pro), and the inputs to each of the rig. Tha

[Elecraft] KX1- 80m and random wire

Hi Elecrafters, For field operations with a KX/40.30.20m, I currently use a 28 feet random wire at the end of a 22 feet pole, and an single 16 feet radial on ground. The computed impedance is 89 - j 341 ohms at 7 MHz, matched by the KXAT1. However, at the low end of 80 m, it should be around 5

[Elecraft] DSP Filters

A question about DSP... I did not find any indication about the exact sequence of filters display in DSP. For instance, lets say that we select CF2 and the tap XFIL; then, the display shows an FL filter. But I am not sure that it is one. If I go through until I get FL1, it does'nt like the nor

[Elecraft] Noise Blanker gain

About the noise blanker: Mine is working fine on all bands except for a particular noise on 40 m. It is killed completly by the NB on all other bands. But it seems that the gain is not always (works some time) sufficient to trigger it at 7,050 MHz. That noise is rising to full strength in about

[Elecraft] BFO Test - CAL FCTR

Update: The problem was at L33. Resoldered and replaced the wires correctly and got back to a good 5 kHz BFO range. Maybe a loose contact or a short on the coil. BTW, I got a tip from another Elecrafter: Since the sole purpose of R116 is to retain L33, adding ''spaghetti" sleeving to the leads

[Elecraft] BFO Test - CAL FCTR

Hi to all Elecrafters I recently built K2/100 # 5170. At the BFO Test (page 62), using CAL FCTR, I got correct readings: Center at 4913,55 kHz, BFO High 4917,23 and BFO low at 4912,41 respectively. But something new is happening. The readings changed to 4913,85 (C), 4915.97 (H) and 4913,58 (L

I actually use that same setup (28' wire and 16' ground, BNC adapter). I get pretty good DX results, and the SWR is about 1:1 on all 3 bands. The end of that antenna is attached to a 22' fiberglass telescopic pole. I would be fine to know about your ''mixed results''? 72/73 de Pierre VE2PID K

The KXAT1 can match a wide range of impedances in steps, using latching relays. I would like to plot all the values using a 3D graph with L's and C's as X and Y axes to obtain Z as the dependant variable. It would be useful to have a spreadsheet or the formulas for the tuning networks (6 nodes m
