[Elecraft] KXV3B preamp or preamps? K3BPF mods questions.

Does the KXV3B include a second preamplifier for the subreceiver or just one preamp for the main receiver? Is the antenna routing the same as before? If existent, can one use the preamplifier for the subreceiver together with the aux input of the subreceiver? Is the antenna routing the same a

[Elecraft] Wish to Elecraft: K3 CWT/Fine & SPOT/RIT

http://elecraft.mailman.qth.narkive.com/QwnNWqcg/k3-cwt-fine-spot-rit I discovered this question there and will join to it. Will the KX3 features: - CWT mode enables FINE tuning - SPOT with RIT enabled tunes RIT, not VFO A be ported to the K3? I liked these features at my KX3 a lot. An

[Elecraft] KSYN3A newest firmware : VCO:MD menu entry still there and delivers error

K3 SN 8887 MCU 5.14 / DSP 2.83 / FPF 1.19, 2/26/2015 Latest Production Release I still see CONFIG: VCO:MD -- and calibration started (digits count uwards) after leaving the menu but ends with an error after some time. I assume this can be ignored, as the KSYN3A does not need calibration? Or

Re: [Elecraft] K3 SUB-RX works , but not in diversity mode

Problem solved to my shame. I forgot to install the coax cable from J4 of the auxiliary KSYN3A to J2 of the main KSYN3A according to page 14 at the KSYN3A manual. Thanks to Wayne for pointing me to my failure. So not the antenna connection was lost but the SUBRX simply got no LO signal. Comp

[Elecraft] K3 SUB-RX works , but not in diversity mode

SUB-RX works (gets signals) but not in diversity mode. I assembled K3 serial# 8887 (FW-5.14) so far succesful but have a problem with the SUB RX and diversity. I plugged the coax from the BNC AUX-RX into the KRX3 at assembly time. When I switch on the SUB RX it gets its antenna input from ther

[Elecraft] KX3 Firmware 1.61 High Current / Low Power at 12m

I updated my KX3 with Firmware 1.61. Criticism: At 12m the output power gets reduced to 5W after the message "high current", sometimes even without this message. This happens with ATU tuned to a SWR of 1/1.2 as well as without ATU at an SWR 1/1.4 then. All other bands did not show this proble

Re: [Elecraft] KX3 AM-breakthrough

Again, thank you all for taking the time to contribute to the issue. Ken, there was a relay of Radio China in Albania but I don't know if it is actually active. Ralf, this morning I "measured" the vfo leakage with my second receiver a NRD-535 connected to a R&S active antenna positioned at abou

Re: [Elecraft] KX3 AM-breakthrough

Thank you all for taking the time to answer to this issue. I will respond to some of the arguments and tips .. Klaus, I already have current baluns at both ends of the coax cable. The KX3 is driven by an analog old PS30 power supply, not a switching power supply. I already mentioned the AM st

[Elecraft] KX3 AM-breakthrough

My KX3 when driven by a allband shortwave antenna shows am-breakthough at all bands above 30M depending on conditions. The source are far shortwave broadcast stations (relative to Germany), Iran, Pakistan, India and sometimes Deutsche Welle. The stations hearable then are different each time a
