Re: Used KX3 Advice, Please

Hi Ron, I saw your post. I own an older KX3 that I bought used from someone I knew. It has worked very well for me. I did not reply earlier, because I am not knowledgeable enough to answer your question. You might get a faster answer from the folks on Elecraft-KX@groups.io. They have active conversa...

Re: Introduction and....

Hey Folks-- glad to be joining the conversation DE KA0GZO (Rob). I am just starting a ham radio reboot as I will be retiring in January. I have acquired some basic kit (Xiegu X6100 and a tactical delta) and would like to get started with POTA and eventually get my CW chops back (or better). I am fe...

Re: 29.5 ft EFRW for QRP

being able to "load" or "tune" if you prefer does not mean efficient radiation a dummy load will "tune" just fine Hi Andrew, I will make no claim about this being optimized as an antenna. It is not. I do find it excellent for field use: it deploys easily, it takes up l...

Re: Long winded introduction from KB0WLF

Welcome, Chris, and thank you for your service. I am a recently retired (2021) newer radio amateur (2020), who also moved out into the sticks. I share your enjoyment of POTA, QRP, and CW. There are lots of good and knowledgeable folks on this site, and it is great to have another enthusiast among us...

Re: 29.5 ft EFRW for QRP

My home antenna is a 35.5/17 EFRW. It works pretty well on all bands, but tuning for 40m is very touchy. I'm thinking of going with a 33 or 35.5 foot counterpoise. Hi Mike, Joshua - N5FY (2nd post above) makes great portable QRP EFRW antennas that are sold at Tufteln.com. One available configuratio...

Re: 29.5 ft EFRW for QRP

This is a great configuration for the KX2! Great to hear good results. How long is your second counterpoise? I’m assuming you are using coax between the radio and 9:1. LOL! Second counterpoise was15 ft of RG316 in a bit of a curly-cue configuration. WX here kept me in the truck for my activations /...

29.5 ft EFRW for QRP

I built and tested an EFRW / 9:1 Unun antenna with 29.5 ft (9m) radiator and single 17 ft (5.2m) counterpoise. With Elecraft KX2 internal tuner, I can reliably tune 60m to 10m bands. I am using it for QRP CW field (POTA) operations, and have had a respectable number of contacts. Deploying it is very...

Re: 13 Colonies

It's been a challenge, but for the past two years I've successfully made clean sweeps of the event operating CW at 5 Watts. de K5UTM I managed to do so also running 5 watts with a wire antenna. I had to use all of my knowledge, skill, tricks, and persistence to pull it off. Use spotting and Hamaler...

Re: What do I need/what is available

Hi MedMan4040, Welcome! A few things in the low cost / no cost price range: 1. CWMorse.us makes and sells a variety of 3-D printed keys. They work adequately for practice and field use. They also sell code practice oscillators. You will need to decide on straight key or paddles, both for the key and...
