Well what would be really useful before would be manuals, even preliminary ones being posted. I'd like to have the mod for power thru the RJ45 connector done so upon arrival it would be plug and play. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 6/9/2016 10:37 AM, Bill wrote: Only six

My experience with two [a small sample] of street lamps, both owned by the State of California [CALTRANS], is that the lamps don't really matter much, it's the controllers ... what we used to call ballasts but that's archaic now. One appeared to be a fairly old high-pressure sodium vapor

Re: [Elecraft] [OT] Street Lamps and RFI

Karl, It might interest them to know if the street lamps (or any other devices) create RFI to licensed radio services (Amateur Radio included), they must turn those devices off and rectify the problem. Of course, the FCC would be involved should that happen, but they must rectify the RFI

Check the connections on the BNC cable between your K3 and P3 and re-seat them. Also, if you have an extra BNC-BNC cable, try replacing this cable. Also, if this BNC is run near switching power supplies etc. it can pick up noise like this. 73, Eric /elecraft.com/ On 6/8/2016 7:22 AM, Sam

If you are using a K3 the K3 and P3 control screens in RUMLogNG are hard to beat on any platform. Also, if you are a DX’er it does a superior job of tracking and displaying DXCC slots and their status. RUMlogNG also has much better integration with LotW and doesn’t require you to use a 3rd
