Is anyone able to get these outside of the US? Just curious...... Though I must admit that I think the FCC is dragging their feet!

General Discussion / Callsign list?
September 19, 2016, 09:27:16 PM
Is there a listing of callsigns for those who are on this forum? Now that I've been introduced to reverse beacon network, I thought I'd keep an eye out for people here and maybe make contact.

Antennas / 22g Polystealth?
July 07, 2016, 10:35:22 PM
I ordered an LNR MTR Endfed a while back which came with 22g polystealth. My cats recently chewed through about 2-3 ft near the matchbox. I've not been able to find any distributors who have the 22g. I'd rather not downsize to the 26g if possible. Any suggestions?

Technical Corner / Good deal on RG-174
July 06, 2016, 02:29:12 PM
I ordered this the other day and figure'd I'd pass along the link. It's 100' RG-174 with SMB connectors attached to each end. I'm not so sure I want to keep the SMB connectors attached on mine as I need BNC, but I figured for the price I couldn't go wrong. $4.99 plus free shipping. Not bad since wireman rg-174 is $0.23 per foot.

Antennas / Need antenna suggestions
June 26, 2016, 11:25:37 PM
I need a new setup... I just don't know what it is right now.

I currently have a ~285ft delta loop. It is suspended approximately 50 ft high with the lower corners being approximately 15 ft off the ground. The feed point is in the middle attached to a 4:1 balun. I believe it's fed with RG58, but I'm at work and can't check for sure. I use a MFJ-971 200W "qrp" tuner at this time. My problem is significant noise. Unless the signal is loud and strong, I get about s7 - s9 on the noise floor.

I'd rather have only one antenna, but based upon what I'm wanting to accomplish I understand that may not be the best route. This is what I'd like to accomplish; NVIS on 80 & possibly 40, DX capabilities when the bands are nice, I wouldn't mind having something mounted in the attic, but the attic's height is only about 12-15 ft, 200w max is all I really need at this time.

I'm open to all suggestions, so feel free to suggest anything.

Description: 
After building two mcHF radio's, and parting one out to help a friend, I've decided to sell the entire setup to fund other radio projects. The mcHF is a small, home-brewed amateur radio project. Firmware is released as open-source and most project files are released as well. Some of the features that the mcHF has are:
Standalone and compact embedded transceiverContinuous RX coverage 2-30 MHz0.5 - 15W output powerCW, SSB, AM and FM – transmit and receive. CW sidetone out without transmitting
300/500 Hz CW up to 10 kHz "extra wide" filters for SSB/AM reception and adjustable passband centeringAlso implemented are additional filtering options such as LPF & BPF specific filtering. Each selectable in all bands & modes.
SSB/AM Transmit Speech processorDSP noise reductionDSP automatic notch filterNoise Blanker & PeakBass & Treble specific values for better usability.SWR, PWR, and S meter.Split VFO operation
Spectrum scope with multiple color & display options
Waterfall Display with configuration options for speed, freq width, and more
Optional touchscreen integration is possible.Cat control & USB Audio functionality

Can someone recommend a good resource on learning how to properly use a radio? I'm still fairly new and without an elmer, learning on my own is slow going... I started playing around with the M0nka mcHF which was great as there weren't a lot of features to get lost in. After purchasing a Yaesu 857d, I'm a bit lost. I'm looking for info on what the Att function is, or dnf versus DNR, etc. The yaesu manual is a bit technical and while it describes the individual features, it's not very user friendly in the "this feature works like this" area.

I'm building a delta loop out back as the random wire in the attic really isn't functional. I'm considering using a couple of 30amp Anderson power connectors to connect each end of the wire to the balun as I'd like this setup to be as portable as possible. I plan on running no more than 150W through this setup and am using 14 or 16 awg for wire. Thoughts?

General Discussion / Intro and mcHF
July 15, 2015, 09:43:26 PM
Hello all. I've been lurking for a while reading all I could. Searching through Tapatalk for QRP led me here. I don't talk much, but will input on subjects that I have some knowledge.

I work for a career fire  department in western Kentucky. I've been EMS/Fire in  some form for 22 years.  I got my Tech class license almost two years now,but fell out of it for a while. I talk 2m & 70cm at work all the time so there was no novelty for me that I thought I would have.  I've been actively working for General now for a could months, and plan to have it soon. So I've never talked on HF yet, never had an elmer, and am learning from scratch.

My drive for General class came when I Googled QRP backpacking radio and found the Softrock SDR. But needing a laptop wasn't reasonable for me.... Then I found M0NKA's mcHF project and just had to build one.  Well, I built one over the past 3 weeks and have it "working", but I don't have an antenna and the three I've tried making all give me the same results.... A waterfall filled with static every the 5 hz or so. No worries, I'll get a known working antenna from a friend later this week; at least I hope so, not being able to talk is killing me. I've heard that with the mcHF, solder issues are usually the problem, so having a known good antenna will help me troubleshoot.

Anyway, my post was twofold, I'd seen someone here post about the mcHF before and figured I'd introduce myself and let everyone know I've built one if anyone has questions. In addition, I like the discussions here and wanted to intro so when I do eventually make a comment, you guys won't be thinking "who's this noob"! Also, typing on a tablet bites, laptop is updating now..... I usually don't make this many grammatical errors, but am too lazy to fix em all.
