The EMH powers up OK and is RXing on what appears to be default factory frequencies (136.45, 155.45, 173.65, 155.45 and 162.55 MHz)?? From channel 6 to 114, all channels are programmed on 150.00 MHz. I understand that the EMH can be programmed using either a DTMF mic or the usual PC and software (EMHedWin1_0_4). The Bendix King DTMF mic is a 6 pin RJ12 rather than a typical 8 pin RJ45 mic I have... Read more View article »

03-11-26 Interesting Readings From Larsen NMOQ2/70B Awhile ago I purchased on eBay a NOS Larsen NMOQ2/70B, an open coil 2m/70cm dual band NMO antenna (in theory an open coil version of the NMO2/70SH). With my NanoVNA* it... 03-11-26, 23:58 pm Awhile ago I purchased on eBay a NOS Larsen NMOQ2/70B, an open coil 2m/70cm dual band NMO antenna (in theory an open coil version of the NMO2/70SH). With my NanoVNA* it has a very sharp match right at 140MHz. I'm talking VSWR of ~1.1 that rises quickly to the point it's above 2.0 before the top of the 2m band. The remainder of the VHF band is totally unusable. It matches better in the 70cm band, but the match was actually best just below the band at around 428MHz. Different mounting...
