    Ended up using an SI5351 module rather than a bare chip on a carrier due to a couple of issues. I figured out what was wrong in the end, but easier just to leave the module in place, it actually ended up saving a bit of space. Anyway, got the MC1496 receiver from SPRAT going.

    Stunning day for Cadair Berwyn, GW/NW-012. On air in 30-60 mins or so.

    Always a hazard having a shop at work and benefiting from staff discount!

    Had the parts to build a programmer to put the bootloader on ATmega 328s for quite a while. This afternoon I've built the programmer and successfully put the bootloader on a fresh chip. This is all to continue with N6QW MC1496 RX project.

    A bit more progress with the N6QW direct conversion receiver from SPRAT. I need to burn the bootloader to the ATmega328 and then load the sketch. I2C LCD is in the post along with a 3v3 regulator for the SI5351.

    Smoke tested my ugly N6QW DC receiver this evening. Still got to add a DDS VFO, but I'm receiving stuff using a sig gen as a LO.

    Hilltop 20 - I've swapped the mixers, now I have Philips SA612, the old ones were Signetics SA602. I've also swapped the op amp back to NE5532 from TL972. Will have to do another SOTA activation to test. In theory the modifications should not make a difference.

    I absolutely love cold, clear days. I can't wait to start collecting SOTA winter bonus points after last year's 'nil points' due to Covid lockdown. Image: this afternoon's view of Ingleborough and Whernside during my daily walk.

    Summited Pendle Hill G/SP-005 this morning in the dark at 0700. I activated on 20m with my MTR-3B, propagation was a bit weird with multi-path at times. Unfortunately no DX contacts but still 23 QSOs in the log (including one on 30m).

    So, if I buy a jacket from Go Outdoors, I have to also pay for membership to the discount scheme at £5/yr. However, if I buy the jacket at exactly the same price from Blacks, which is under the same company umbrella, I don't have to buy a membership, how does that work?

    Gave my HT20 a test drive on G/LD-052 Hutton Roof Crags this morning. I changed IF from 5.185 to 4.915MHz. Seems like I still have work to do, it's better but appears to need more gain. Oh, and the keyer hates me!

    Ordered some LM380 DIL chips from a private seller on ebay, the chips arrived in an envelope. 🤦‍♂️

    35 QSOs from Buckden Pike G/NP-009 this morning, including 2 on 160m. Reached the summit at 0705utc, trying to beat sunrise!

    Oh gosh, it looks as though I now have a power amp to build! I don't look for projects, projects find me!

    Planning to do SOTA on Saturday morning around 0900 - 1000 utc. I can't decide which HF bands to take. Haven't been on radio since September.

    Finished the 20m rig, working well. I used a 1SV149 varicap for frequency shift. (I'm saving my MV1662 and MVAM109 for now).
