The HP 8350B with the 83522A plugin is drifting. There's a setup to keep the frequencies stable. The HP 5343A and 5344A are available for this. I'll rebuild the setup.

A quick review of the multimeters HP 3455A and 3456A with my own highly accurate resistance standard. I will soon build some more to order.

Good night and sweet dreams. Greetings from the star destroyer.

I set up the first devices in the new laboratory. The electronics laboratory is now fully air-conditioned. Stable temperatures for calibration. Soon the work tables will be set up. #hp #agilent #keysight #tektronix #rohdeubdschwarz
I'm gradually replacing my HP and Supermicro servers with Dell servers. Today I put the first Dell R730 into operation with Proxmox.
My vintage computer collection is very large. Today I have outsourced a first part. I also need to reduce some of the Apple collection. #vintagecomputer
Ne too :)
RTTY Display on microHAM micro Keyer III and Icom IC-7610
Beautiful 😍

That's coming from the audio interface. I don't know why. The 7610 is much better than the 7300.
The microHam Micro Keyer III is now running on Linux. CAT control and audio are working fine so far. However, I'm still getting strange background noises when sending in digital mode.

I haven't found a PSK report yet either.
OpenHamClock as an alternative to HamClock! Completely new development, and it's being expanded with new features every hour.
I'm excited
it's going to be great!

An update on the lab floor renovation. The flooring is finished, and the lighting is installed. The door and electrical outlets are still missing. I could start planning the lab benches.
Soon the air conditioning will be installed.

I now have an IC-7610 and it exceeds my expectations.
Who has a 7610 with MicroHAM Micro Keyer 3?

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.

The new place is not ready yet but I am QRV. The new desk still needs to be built. #hamradio #amateurfunk #icom #ft8 #tetra
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
Our lab cat Peter is tired.
Brush your teeth, go pee, off to bed! #meow
I have now switched from Pi-Star to WPSD for DAPNET and POCSAG. I hope this runs more reliably.
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 finally made it. Switch the Cisco IP phones from SIP to SCCP firmware and operate with SCCP Manager on FreePBX 16 with Asterisk. It took me all day until I had a working version.
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
I got a CW paddle from my family for Christmas. Now I should learn CW, I'm thinking if there is learning software for Linux?
I am now also on 23cm QRV. With an X5000, the nearby relays are reachable. But I still have to use a better cable with less damping. #icom #hamradio
Oh very hot!
An HP 346B Noise Source for an HP 8970B Noise Figure Meter. The HP 8970B can only handle 10 MHz to 1600 MHz (2047 MHz Optional). The Noice Source goes up to 18 GHz.
I'm going to do a few experiments with it.

Ich war auf dem Fichtelberg 1214m im Erzgebirge. Dort gibt es ein Amateurfunkrelai DB0FIB. Die Funkrelaisstation bietet 70cm FM, DMR, C4FM und D-Star. Dazu noch 23cm FM und 2m Lineartransponder für Allmode. Das Relai ist im Sachsenlink Verbund. #fichtelberg #hamradio #amateurfunk
