Advice on VHF Transverter for SSB use

Hi Rudi,

in my opinion the transverters from Ukraine are good value for the money. They are OK to add new bands to your station, but you will not get a competitive VHF DX station for that price tag.

I have two of them (28MHz/70MHz and 28MHz/432MHz) and would buy them again. They are no high end products and you have to accept a number of weak points.

For me the oscillator stability was a real problem. The frequency drifts quite fast with the board heating up during transmission and cooling down during reception. Narrowband operation (e.g. FT8) was nearly impossible, so I added external OCXO controlled oscillators. If you want to use the transverter for SSB only, the drift is noticable, but in normal QSOs not really an issue.

Sorry for playing my own harp but as to frequency stabilisation, have a look at this discussion on the forum: 432/28 MHz transverter from transverters-store.com

As to the Anglian converters, they are good but parts may be an issue.

Keep in mind that for QO100 the dynamic range is limited. On WebSDR, the beacons are less than 20dB above the noise floor and stronger signals than that yield QSL's from LEILA. My suggestion is to focus on reciprocal mixing given the relatively high noise floor. In my experiments, I find that receivers that are quoted to have good LO's give me better signals.
