Galvanic isolated Sound Interface

Some time ago I already built some "loose" interfaces for my FT-817. I used these later on my FT-891. The CAT, respectively the FTDI USB to serial converter I needed at the FT-8x7, I don't need at the FT-891 anymore, because it already has CAT via USB integrated. The FT-891 simply uses a Silicon Labs CP2105-F01 USB/Serial UART converter internally. As with many other TRXs, this is not galvanically isolated, but the engineers thought of something. Apparently it works well anyway. I have had no problems at least in the last 2 years. In this article I show you my solution for this problem.

1000 points Mountain Goat

Some quick shots from this week while we did some SOTA in the in the northern Black Forest region. We started on Hohloh DM/BW-054 984m. The next day we went to Hornisgrinde DM/BW-019 1163m. After those 2 I had 994 SOTA Points, only 6 points short of the so hard wanted iceblock trophy.  We then drove one hour further south to the Brandenkopf 945m DM/BW-067. I was not prepared for this (battery-wise) and we hoped that somehow 4 QSOs would come into the log. It became then nevertheless even 10 QSO, until the device switched off from the low voltage. Now I am SOTA “Mountain Goat”. After 177 SOTA activations in 7 countries in 5.5 years. I already ordered the award and I applied for the trophy.

FL/VO-023 Le Donon

Last year in December I wanted to activate 2 mountains in the Vosges. These two are not too far from my home town. Both could be done from the same parking lot. That day it was below 0 degrees °C and we had freezing rain on the Petit Donon. But in return we got 3 points winter bonus each in addition to the 2 times 10 points. 26 points with only one parking stop is not too bad. I was already on the big Donon at the end of 2017, actually you have to go there more often. Simply very nice there. 13 QSO vom VO-023 on 40m and 20m SSB. Exactly 2 hours after the last QSO we logged the first one from VO-090. 16 QSO here on 40m and 20m SSB with best DX AE7KI in TN. Always great to work DX with 5W.

SOTA: EI/IS-127 Carhoo Hill

After EI/IS-050 Torc Mountain the day before we took EI/IS-127 Carhoo Hill 02/Jan/2019 with great condx. Worked a lot US and VE. Thank you GM6ZAK, EA2CKX, EA2DT, G0VWP, G4AFI, M7AFI, DL5AWI, G3OCA, IK2LEY, DG1NPM, F4HZR, S54KD, DL3KZA, AB4PP, N4EX, AA1VX, SV2RUJ/P, VE1WT, SP9ETA, KB9ILT, (18 MHz!). I can highly recommend Ireland. What a great landscape!

SOTA: EI/IS-050 Torc Mountain

Unfortunately, at the moment I don't always get the chance to publish everything up-to-date. Therefore now also with a delay of 1.5 years. Our hotel was in Killarney, so it was a good idea to activate EI/IS-050 Torc Mountain on New Year's Day, 01/Jan/2019. Condx sucked, but I wkd: 2E0WDX /M, IK2LEY, EI3KA/P (S2S), EA2CKX, EA2CE and SA4BLM.
We needed 4,5h from the parking lot to the top and back. Great to chat with EI3KA/p some 30km away on EI/IS-095 on 7 MHz, 14 MHz and 145 MHz.

BNetzA Amtsblatt Mitteilung Nr. 111/2020

Heute morgen staunte ich beim Frühstück nicht schlecht. Es gibt Änderungen bzgl. des 6m Bandes.
