NQ4T Field Day Setup

Due to the downfall of society and shit hitting the fan; I have been forced to operate Field Day as a Class D from home rather than going out and enjoying it with friends. I focused my anger in to getting a station setup:

iCom IC-725:

The good ol’ IC-725 I promised I’d never get rid of. After having to get rid of the 7300 it was a good decision as it still left me a radio. The radio sucks..it’s RX section is a total embarassment and it’s going to make FD so much more difficult since SSB stations 16khz each side of you bleed through.

TenTec 715:

This is an RF Speech processor…it’s just proving the screaming DX sound that boosts my average talk power.

$10 PC Headset:

I modified this PC headset to plug in to the TenTec; a second cable from the rigs headphone jack provides the audio. It’s cheap, but effective.

Clipper Foot Switch:

If I can’t make QSOs with it, I can bludgeon someone with it. A stupidly over-engineered footswitch…it’s cast iron body and heavy duty construction means it’ll put up with even the angriest of QSOs while fighing a pileup.

“Generic Sandwich Cookie” Interface:

This is the digital interface I built 5 years ago. Sound card, isolation transformers, opto isolator.

Simple Level Converter for CI-V

A simple 7404 based level converter that allows me to take an Arduino Uno board (sans ATM328) and do CAT/CI-V.

Software wise I’m running N1MM logging integrated with MMTTY, 2Tone, and WJST-X. This should allow me to oprerate both phone, RTTY, and FT8/4 during the contest.

I’m going to try and work all 24 hours. It was a tradition that I stay up and work the night shift for FD; I broke that last year along with everything else. But running solo as a Class D; well, it’s all on me.

Yes..this was a quick post; but FD starts in 30 minutes. I’m largely already set. Everything is wired; everything is configured. It’s hot…man is it hot. 90 degrees with humidity to match in an unairconditioned shack. I have a fan blowing on my legs and up my body…people are going to have to deal with the background noise. One person I did a QSO with already said they couldn’t hear it.

Oh well. Good luck everyone.

Upgrading Hotspot & MMDVM USB Tricks

I’ve been a fan of screwing around with the MMDVM hotspots ever since I picked up a ZumSPOT with my D74. Though I remember them being around when I got in to ham in 2015; they’ve gotten a lot cheaper and a lot more universal.

Anyway; I upgraded one of my hotspots and did a neat little trick with my now spare MMDVM HAT.
