Vhf transverter

The converter store transverters (2/440) receive great, with 20db of receive gain. The transmit function is a whole "nother" problem. Using the K3s in 2 tone on 28 Mhz, I viewed the 2M transmit signal on my Rigol 815 at a range of input drive levels, through a 40db pickoff, and the IM products were less than optimum.

To answer my own question: This guy in Ukraine sells very reasonably priced transverter boards/boxes for individual ham bands to the top end of HF. Note there are several different models per band that use different oscillator frequencies (e.g. 144:148 => 28:32, 144:148 => 26:30, 146:150 => 26:30) and also models that have a more expensive TCXO rather than a. How to very easy and cheaply turn any of your HF 10m band transceiver or CB with 10m band in to a VHF/UHF radio. Especially a great idea for HF SDR's owners. The smaller one is for the VHF transverter, and the larger one is for the HF amplifier. The design is just a series of 1/4″x1/4″ grooves in the 3/8″ aluminum, with some extra material left at the bottom to tap in to for mounting in the case. The design works out nicely because the router bit that I used to cut the material was also 1/4″. The only "drawback" of the combination is the '7300 does not support a transverter frequency display, i.e. you can't set the display to show the end frequency like 144.300 MHz but will only see the IF frequency (28.300 MHz in this case).

The FlexRadio Systems FLEX-1500™ QRP Software Defined Radio is ideal for interfacing to VHF transverters. Papers have been presented on the subject (i) that covers various implementations in great detail. This article. This transistor energises a 10-volt relay, RA/2 having two changeover contacts. One contact set routes the VHF TX/RX antenna signal to the TX or RX mixers, as appropriate. The other contact routes the input 10-volts supply to the TX or RX mixers, as appropriate. The TX mixer +10-volt supply is also used to energise an external TX/RX relay. I use their transverters on 10 GHz, 24 GHz, 1.2 GHz and am very happy with them. The IF radios here are various HPSDR projects and they all work well with Kuhne and other transverters.

The LO performance of a HF radio with upconversion to a high IF should be slightly better than that of a 144 MHz LO because its frequency is a bit lower.
