Panadapter on a budget! Revival of the G4HUP PAT Board.

I recently acquired a shiny new Yaesu FT-450D. I knew almost immediately that I wanted to use one of my many RTL-SDR dongles to set up a pandapter. As luck would have it, all the hard work was done for me by Dave Powis, G4HUP. He had designed a compact, high-impedance IF tap for direct connection to any SDR. Unfortunately, with the passing of Dave came the end to all shipments of the PAT board, leaving me high and dry in the search for a cheap way to add a panadapter.

Updates & Wiki

Hi all!

It’s been a while since my last post. School and life has kept me plenty busy, but I’ve been trying to get a few new blog posts up. It’s hard to dedicate enough time to get quality content up – and that’s why I launched the W3AXL wiki earlier this year. I’ve learned quite a bit through my repairs and modifications of Motorola equipment, and instead of talking several hours writing a blog post, I’ve opted to instead update this wiki with information all about various Moto products.

Visit the wiki here!

You’ll be seeing new pages and updates as I add more. If you feel like contributing, shoot me an email and I’ll get you set up with an account for editing and creating pages.

That’s all for now. Sorry for the short post but like I said, free time is in short supply these days!

Building a No-drill Antenna Rack for Your Car

There comes a time in some hams’ lives when they’re faced with a dilemma. They can’t drill their car, the mag mounts are getting old very fast, and trunk lip mounts just won’t cut it. The misguided of the lot go towards glass-mount or fender-mount antennas, and settle for poor performance and high losses. The more adventurous, well, we get creative. So if you’re like me and you want to mount a whole bunch of antennas to your car but don’t want to drill the roof, this is the story you want to read.Read More

The Comet RS-720 NMO Mount – A Review

DISCLAIMER: I’m not paid for any reviews I write. Hell, I wish I was; it’d bring in more money for fun radio stuff. Be assured my reviews are 100% my own stream of consciousness.

There has never been a more controversial topic in ham radio than that of mobile antenna installations. Half of the world thinks that everything can be solved with a good hole saw through the roof. The other half is reasonable and understands that sometimes that isn’t an option. Let me preface this by saying that yes, in most situations a drilled and sealed NMO mount properly installed will outlast and outperform any temporary mounting method. However, for those of us who aren’t able to permanently change things about their vehicle, be it for rental or lease reasons, or maybe your significant other just doesn’t want any holes in the car. Regardless of the reason, just because you can’t drill doesn’t mean that you have to settle.Read More

The Motorola Railroad Spectra – part one

As well as being a ham radio operator, I also am a huge rail buff. As such, I had long wanted to add a railroad radio to my collection. Unfortunately, the only ones to be found for sale were either old radios from the 80’s with limited feature sets, or newer Astro radios from the big M that were way more than I was willing to pay for a radio.

Fortunately I was able to stumble on a for-parts Motorola Spectra on ebay for a very, very decent price with shipping. The radio was advertised as untested, but pulled from a working environment. I jumped on the item and within a week it was at my door.

So began a not-so-fun journey into the mystical ways of railroad-grade equipment and poor documentation.

Tytera MD-380 Initial Impressions

DMR is the hot new digital mode that everybody seems to want a piece of, even though it’s been around for several years. The real reason everyone’s been jumping aboard is the rise of inexpensive DMR portables, specifically ones like Tytera’s MD-380.

For $170 US you get a fully functional UHF digital radio that can do both conventional analog 70cm as well as DMR communication. Previously radios like the XPR line from the big M were going for upwards of $500 used, so this is a welcome price drop. It’s not unlike how Baofeng revolutionized entry-level radios a few years ago when they came out with a dual-band HT for $35. Now people with a modest budget will be able to get on DMR repeaters and talk to people all over the world, without a costly HF rig.

I was able to get my hands on one of the 380’s for cheap and have been playing around with it for the past few weeks.

Welcome to the site!

Hey everyone. My name’s Patrick, and this is my blog.

Alright, now that we’ve got that out of the way, let’s get down to business. This is going to be where I post all of my amateur radio ramblings, reviews, repair logs, build logs, and general bullshit that I feel like posting on any given day. Now this isn’t going to be a dumping ground, but it is by no means going to be a professional website about the technicalities of operating amateur radios.

Speaking of which, let’s talk about that a little bit more. I’m currently licensed as a technician in good ol’ Indiana, USA. I was licensed in July of 2015 and have been found all over the 2m and 70cm bands, and even on the 6m bands from time to time.

I’m currently stuyding electrical engineering at Purdue University and am an active member of the oldest club at Purdue – W9YB. Along with my friends, we do all sorts of neat stuff with amateur radio. Our new DMR repeater has been one of the most successful projects we’ve worked on, and it is currently the most-used DMR repeater in the whole state. We also have a 2m and a 6m repeater which are both used quite often, and we’ve got plenty of vintage radios and test gear in the shack to please even the most veteran ham.

So stay tuned for more posts, and hopefully I’ll remember to put things out at a somewhat reasonable pace.

Thanks for watching!
