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 …

Again good tropo to Spain

Today, there is good tropo propagation to Spain, again. Last time activity went up in FT8 on 144 MHz, this time stations also moved to 432 MHz FT8. Spain is a new DXCC for me on 432 MHz. Also one new grid already confirmed via LoTW on 144 (EA1MX in IN73). Loud signals from stations …
