Working on new features tonight for #QRV

Favorited callsigns will highlight recent spots (incl. multiple bands) on the Lookup page; tap into it for more detail. With a QRZ logbook subscription, searches will also show worked bands and confirmation status.

Finally ditched Windows on my gaming PC and installed CachyOS. I have plenty of experience with Linux (including my Steam Deck), but it still made me nervous! I'll probably have to use a VM for a few niche radio apps (DMR programming, etc).

#QRV 1.1 is out! I added power/voltage/current calculations and suggested wire gauge based on those numbers. Also a few bug fixes, of course. #AmateurRadio #HamRadio

I'm already working on v1.1 of #QRV. In addition to the usual bug-fixes and polish, I am also adding a Power/Current/Voltage calculator with wire gauge recommendations. The calculator also includes a chart to help you convert between AWG and mm^2. #AmateurRadio #HamRadio #iOSDev

Black Friday is great because it helps you unsubscribe from all of those marketing lists you forgot about.

#QRV has been submitted to the App Store for review… now we wait. As with all software, I had to feature-freeze myself lest I never get 1.0 out the door. Thank you to everyone who beta-tested and gave me feedback! #iOSDev #AmateurRadio #HamRadio

It's an incredible bind that these financiers put society in. You basically have to do a bailout, because to simply let the bubble pop would be even more devastating for the entire country.

There is no democratic input at any part of this process, whether bubble inflation or bailout.

One of my beta testers asked about DXCC, ITU zones, and CQ zones. Ask, and you shall receive (a reference page)! You scroll all or filter the view.

I'm targeting a 1.0 submission date of November 30th, so it's crunch time.

#QRV has widgets! Still tinkering with the design, as there's a lot of info to include. Let me know what y'all think, and remember that I'm still accepting beta testers: testflight.apple.com/join/4K2TBGSx

Really pleased with my latest work on #QRV. Behind the scenes, I'm tinkering with how to monetize the app without being a jerk.

Cooler though, I've done a first pass at adding filters to Live Spots. You can now see all spots, filter by continent, or by selected DXCC. #AmateurRadio #HamRadio #iOSDev

Things you don't consider when hosting your first API: what if Cloudflare goes down and you didn't set up a way to notify users?

Going to set up a simple status JSON on Github that can be fetched on app launch. I'll just add a note to that repo when needed.

Lots of #QRV news! While trying to implement more features in Live Spots, I ran into a lot of issues with the PSK Reporter API. The maintainer confirmed that it's not really designed for my use case. Instead, I was pointed here: mqtt.pskreporter.info.

Hey! Did you know that I'm beta-testing a new app for ham radio operators? It has call sign lookup, live spots, band conditions, and handy references. You can join the beta for free here: testflight.apple.com/join/4K2TBGSx

Tonight's #QRV update:
I've added a lot info and calculations around making 1/2-wave dipoles and EFHWs. I also cleaned up some of the UX in the calculator to make it more intuitive when you switch units, etc. The screenshot shows calculations for a 40m EFHW.

Not much progress on #QRV tonight, but I did add some reference material for HF. I'm still stuck about what to do for a repeater database, but I think there's a real need for something more open. If you want to help test my multitool for #HamRadio operators, sign up here! #AmateurRadio

Today’s #QRV update. I asked around on my club’s morning Net, and folks suggested that I add some reference material: phonetics, Q-codes, etc. So I’ll tackle that after work today. Maybe some other stuff like typical repeater offsets, too! #hamRadio #amateurRadio #iOSdev

Took a day off from #QRV development to build a new Guitar/Clone Hero controller. Today I'll tackle time filtering for live spots (15min, 30min, 45min, 60min) and start thinking about user onboarding. #hamRadio #amateurRadio #iOSDev

Tonight in #QRV:

I'm working on live spots with data from PSK Reporter and your grid square. My results are differing from those in HamClock, but it's possible that we use different approaches. The ratio of spots is what's really important, I guess. This one has been tough! #hamRadio #amateurRadio
November 7, 2025 at 11:40 PM
Today’s #QRV development update: the app now presents band conditions from HamQSL, and it gets your gridsquare from your current location.

I’m realizing now that all of my features are HF focused, so maybe VHF/UHF is for an update. We’ll see! #hamradio #amateurradio #iOSDev

An update on my iOS app for ham operators! I was able to pick the name QRV on the App Store. It now pulls call sign info from QRZ and HamQTH for quick lookups. The user can login to one or both. If both, they can set a preference, but it will always fall back to the result with more complete data.

I'm working on a multi-tool iOS app for #hamradio operators. What would you like to see? I already have quick callsign lookups and repeater info planned.
