Image transmission from the ICOM ID-52 to the IC-705 via D-STAR is a really nice feature. 😻 #meow

Bosco @boscomac.bsky.social · 26/09/2026

I’m experimenting with D-Star on my Icom radios the ID-52E, IC-705, and IC-9700. The repeater lists found online are all more or less flawed; sometimes repeaters are missing, or the frequencies are incorrect. I guess I’ll just have to create everything manually myself.

Perform final checks on the filters for the TETRA relay. The bandpass filter isn't 50-ohm compliant at 430.625 MHz :( #tetra #vna #hp #agilent #keysight #hamradio #amateurfunk

The TETRA diplexer shows good transmission and reflection characteristics. The SWR for RX and TX is 1.17:1, which is good. #hamradio #amateurfunk #hp #agilent #keysight #tetra

Bosco @boscomac.bsky.social · 30/08/2026

First, measure the TETRA repeater diplexer and check for any deviations. #hp8757c #hp8341B #hamradio #tetra #amateurfunk #keysight #agilent #hp

A quick trip to the station to check the TETRA signal. Power is fine, but the signal is poor. Taking the diplexer filters to the lab for tuning. #tetra #hamradio #amateurfunk #w34 #DM0WSF

I finally have the Yaesu rotator and the Yagi antennas up on the roof. Now satellite radio operations can begin. #hamradio #darc #amatuerfunk #satellite #amsat

Good evening from the shack. I’ve discovered that the IC-7610’s internal tuner on ANT-2 can operate independently, even while an external tuner is active on ANT-1. 🫣👍 #hamradio #icom #amateurfunk

Conversion to a new TETRA repeater.

Bosco @boscomac.bsky.social · 26/07/2026

This is a massive plastic tube. Very light, the antennas are also all very light. A counterweight is not necessary here. 👍

Bosco @boscomac.bsky.social · 26/07/2026

Yes, that could be the arrangement for 2m, 70cm, 23cm, and 13cm Yagis on the Yaesu rotator. Everything horizontal for direct SSB and space communications. Maybe EME? 🙈 #yaesu #icom #hamradio #amateurfunk #amateurradio #sat #eme #antenna

Ich überlege meine erste POTA Aktivierung zu machen. Erst mal mit FT8 und später SSB. Ich möchte aber auch ein Biosphärenreservat auf der Karte eintragen und dann aktivieren. Hat jemand Erfahrungen? #pota #amateurfunk

I had to take the IC-705 out of the bag it had overheated.

Das zweite CW QSO mit einer italienischen Station lief besser. 🫣

Mein erstes CW QSO … ich war so schlecht 🙈

Bosco @boscomac.bsky.social · 15/07/2026

Ich werde mich mal in CW probieren. Vielleicht bekomme ich heute Abend ein QSO zustande.

Bosco @boscomac.bsky.social · 15/07/2026

I spontaneously tested SDR Control with the IC-705. I think it's very good. FT8 works well. I'll be testing CW. #hamradio #amateurfunk #ft8 #ic705

Bosco @boscomac.bsky.social · 07/07/2026

80m is almost unusable at my QTH. I’m seeing a local noise floor of up to S9+20 dB, most likely caused by man-made interference from nearby. Weak signals are completely buried. #hamradio #amateurradio #HF #80m #EMI #RFI #QRM

The 70cm band Yagi has two arms and waves like Stan S. Stanman from Monkey Island. 😂 #hp8753B #hamradio #smithchart

I am investigating the thermal behavior of an MW LRS-350-12 without a fan and am trying to replace the original fan with a quiet one. #hamradio

For 23cm I have a IC-9700 and for 13cm I'm looking for an IC-905 😎

For the satellite radio operation I have almost everything together. Yagi antenna for 2m 70cm 23cm and 13cm. #hamradio #amateurfunk

I am looking for a CSN S.A.T. Tracker and a Yaesu 5500 DC rotor. The Sat Tracker is not available in Europe? The 5500 rotor is also hard to get. Who can help? #ic9700 #yaesu #hamradio

I test the clockwork uConsole with the ICOM IC-705 with FT8. That's a nice little setup. #hamradio #linux #ft8 #icom

Bosco @boscomac.bsky.social · 20/05/2026

Because the 80m band is so unusable still a bit of FT8 on 15m. #icom #ic7610

Bosco @boscomac.bsky.social · 19/05/2026

Absolutely fantastic the uconsole. I'll try a few things. #clockworkpi #hamradio

After 9 long months of waiting, the uConsole has finally arrived. #clockwork

One of my HP 3456A shows -9.0 in the self-test. Is there a reference list for the error codes?

010

Bosco @boscomac.bsky.social · 30/04/2026

From prototype to product. But somehow the product is still a prototype.

That would be a good candidate for a display replacement. A Fluke 5442A Direct Volts Calibrator. #fluke #voltnuts #hp3458a

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. #hp #agilent #keysight #rohdeschwarz
