High quality measurements on a low-pass filter for a POCSAG transmitter. I use my favorite Vector Signal analyzer HP 8753B. #hp #agilent #keysight #hamradio #dapnet

The board even works on #Raspberry Pi Zero 1st generation. Could use some very old birds as #DAPNET transmitter controller. #hamradio #dapnet #pocsag

Made a little PCB for simple #DAPNET transmitters. Audio and PTT via GPIO port of #RaspberryPi. No extra connector for audio jack required. #hamradio #dapnet

Quick and dirtry creation of a small #RaspberryPi HAT PCB to overcome prototype setup with flying wires. This should enable #UniPager to deliver audio and PTT signal via 40pin header (instead of 3.5mm jack which RPi 0 does not have). #hamradio #DAPNET

Welcome to the future! I love these old Skypers and they have a new life in DAPNET! POCSAG is a great protocol for messages in one direction. #pocsag #dapnet #hamradio #amateurfunk

The festival of harmonic measurement after the power amplifier has begun. The power amplifier for 70 cm already has a low-pass filter built in. But I'm still missing 10 dB. #dapnet #pocsag #hp #agilent #keysight

I test an MMDVM_HS_HAT duplex for POCSAG in DAPNET. I check the signal and the harmonics. Later a 70cm amplifier should be connected with filter for the harmonics. #hamradio #hampager #dapnet

Personal messages stop being sent after a while, only after a service restart or a Pi reboot. However, the other RIGS messages are always sent. I've seen in the log that the message is coming from DAPNET but isn't being sent. #DAPNET #POCSAG #PiStar

I will build a transmitter for the #DAPNET. Material is ordered. An MMDVM with a 70cm band amplifier with 10 watts. Who has experience with it? #Pocsag

Testing a #Motorola GM1200 with #Raspberry Pi 4B and audio out on GPIO pin header. Just #Unipager does not want to steer a GPIO pin for PTT. Grmpf #dapnet #hamradio

Just worked OK/@DL6AP in Czech Republic 🇨🇿 (Gridsquare: JO60 / distance: 417.5 km) on SO-50 🛰️ (11.4° el / 327.9° az) using FM. Got alarmed by #DAPNET page. #APRS position seems a little outdated. Tnx QSO Andy 😎✌🏼 #hamr #wavelog #amsat

Home brewed a micro-USB OTG to USB-C cable directly connecting #RaspberryPi Zero 2 W to #DingleBop v0.6. No OTG adapter + separate cable needed. #hamradio #dapnet #svxlink #direwolf

Fixed the #DingleBop PCB and it’s working good now. Got the pager alarm for upcoming grid line activation by @N4AKV_ at 04:05 in the night 😂 #amsat #hamradio #dapnet

Guess I need to add a date to the pager messages. Almost went out to work @W8LR_Jerry until I noticed that it’s weeks later. 😂😂 #amsat #hamradio #dapnet

Getting https://t.co/otAeZftqYz posts/alarms on my #DAPNET pager. 🛰️. Think I need to implement a 2nd alert with some lead time prior to AOS to be able to reach the local SAT summit 😅😇 #amsat #hamradio #dapnet

Updated and compiled #UniPager on #Debian running on a #RaspberryPi. hidraw and alsa device names made static using an #udev rule. Some notes on the blog: https://t.co/NkXbyXPJGB #DingleBop #hamradio #dapnet

Finally made a new revision for #DingleBops. USB sound interface for #Motorola GM3x0 radios. This time new CM109 chip and interface refactored to USB-C. Works with #Svxlink and #direwolf. Hope to get it running with #Unipager for #DAPNET as well. #hamradio #diy
