The FT8 farmer
Did I already mention rule 1 till 3 if you transmit in digimodes? 1. Check your ALC 2. Check your ALC 3. Check your ALC Don’t be a farmer spreading out harmics on the complete spectrum like the guy below. Your ALC shout *not* come in red. Or even better: not giving a bar at …

Icom IC-9700 Inside Pictures
Today, Robin (G1MHU) posted some pictures on Facebook. Embedding the pictures doesn’t work but follow this link to see them. Looks like Icom already added a foam block on the TCXO for stability. But. There is enough room to add a heater, cooler, whatever inside the box.

Pluto SDR hack: Add a 2nd CPU core
The Pluto SDR is easily ‘hacked’ to extend the frequency range from 325-4000 MHz to 70-6000 MHz as described earlier. Another hack is to enable the 2nd CPU core on the ADALM Pluto. After logging in to the unit, ‘cat /proc/cpuinfo’ shows only one core. Now enter ‘fw_setenv maxcpus’ in the console and reboot the …

Icom IC-9700 and 10 MHz GPSDO lock
Many people are confused about the 10 MHz reference lock input on the IC-9700. And so was I. While all of us expected the VCXO was locked to the 10 MHz input (which in most cases will be locked to a GPSDO) it isn’t. Unlike the new IC-7610, which is locked, the 10 MHz input …

April 2019 NAC contest on 1296 MHz
Only worked for 1,5 hours. 8 QSO’s in 7 grids. ODX: SK7MW (617km). I had to run low power due to the IC-9700 Power Overshoot. 🙁

Icom IC-9700 Power overshoot
Damn you Icom. Again, and again, and again. Yes. Alse the IC-9700 is equipped with the famous ‘power overshoot’ or ‘ALC overshoot’ issue most modern Icom transceivers have. Apparently Icom can’t get a grip on this issue. Bad news for people using transistor based amplifiers (SSPA) in SSB mode. Since the IC-9700 had a ‘TX …

Icom IC-9700 frequency modification
The first IC-9700 frequency modification appeared online. Marcus (PA2DB) from HamShop.nl posted this. The modification only works on European models and by removing 2 diodes the frequency can be expanded by a few MHz to the USA market. That means 2 MHz extra from 146-148 MHz (which is a welcome modification for UK users since …

April 2019 NAC contest on 432 MHz
The most remarkable tonight were the very poor conditions. I was able to work Dan (OZ1BEF) as usual, but with 55 signals maximum, with the help of airplane scatter. Normaly his signal is always 59+. Another stations further away that should always be workable is SK7MW but tonight I didn’t hear the Swedish club station, …

EAntenna 5070OWA9
April. The Sporadic E season is about to start. And since my last antenne for 50 and 70 MHz didn’t survive a storm it is time for a new one. This time I bought the 5070OWA9 fom EAntenna at the local Hamshop. It is a 4-element antenna for 50 MHz and a 5-element antenna for …

Icom IC-9700 hidden telnet service
My Icom IC-9700 is connected to the network. And, as a freelance linux and infrastructure (security) engineer, I could not resist to do a port-scan on the box. The first result was port 23, used for the legacy telnet service. Loggin in was easy. No username and password required to get a shell. Quite shocking …

Icom IC-9700 and N1MM+
The problem with new transceivers is the lack of support for drivers in programs like Ham Radio Deluxe, WSJT-X (OmniRig), N1MM+ and MicroHam drivers. Just to name some programs I juse often. After playing around I found a way using the IC-9700 with N1MM+ by emulating an IC-7300 wich has about the same architecture. All …

The new Icom IC-9700 is in
The frst batch of the new IC-9700’s arrived today at Hamshop. I was the first one to collect mine, ordered back in September 2017 hours after the announcement during the Tokyo Hamfest. After unboxing I notice the DIN connector is missing. From all Icom transceivers I’ve bought in the past, the DIN connector for accessoires …

April 2019 NAC contest on 144 MHz
Only worked 2,5 hours. 25 QSO’s in 17 grids. ODX: SQ6POM (716km). My result: 4th place in the Netherlands. It could be the last NAC with the FT-817 since the IC-9700 will arrive today. If this Icom doesn’t have the ALC / Power overshoot like all Icom’s have, it should be safe to feed the …
